Juergen Gross	bb7645c338	mm, page_alloc: fix build_zonerefs_node() ... commit e553f62f10d93551eb883eca227ac54d1a4fad84 upstream. Since commit 6aa303defb ("mm, vmscan: only allocate and reclaim from zones with pages managed by the buddy allocator") only zones with free memory are included in a built zonelist. This is problematic when e.g. all memory of a zone has been ballooned out when zonelists are being rebuilt. The decision whether to rebuild the zonelists when onlining new memory is done based on populated_zone() returning 0 for the zone the memory will be added to. The new zone is added to the zonelists only, if it has free memory pages (managed_zone() returns a non-zero value) after the memory has been onlined. This implies, that onlining memory will always free the added pages to the allocator immediately, but this is not true in all cases: when e.g. running as a Xen guest the onlined new memory will be added only to the ballooned memory list, it will be freed only when the guest is being ballooned up afterwards. Another problem with using managed_zone() for the decision whether a zone is being added to the zonelists is, that a zone with all memory used will in fact be removed from all zonelists in case the zonelists happen to be rebuilt. Use populated_zone() when building a zonelist as it has been done before that commit. There was a report that QubesOS (based on Xen) is hitting this problem. Xen has switched to use the zone device functionality in kernel 5.9 and QubesOS wants to use memory hotplugging for guests in order to be able to start a guest with minimal memory and expand it as needed. This was the report leading to the patch.

Alistair Popple	a74bb0eeab	mm/pages_alloc.c: don't create ZONE_MOVABLE beyond the end of a node ... commit ddbc84f3f595cf1fc8234a191193b5d20ad43938 upstream. ZONE_MOVABLE uses the remaining memory in each node. Its starting pfn is also aligned to MAX_ORDER_NR_PAGES. It is possible for the remaining memory in a node to be less than MAX_ORDER_NR_PAGES, meaning there is not enough room for ZONE_MOVABLE on that node. Unfortunately this condition is not checked for. This leads to zone_movable_pfn[] getting set to a pfn greater than the last pfn in a node. calculate_node_totalpages() then sets zone->present_pages to be greater than zone->spanned_pages which is invalid, as spanned_pages represents the maximum number of pages in a zone assuming no holes. Subsequently it is possible free_area_init_core() will observe a zone of size zero with present pages. In this case it will skip setting up the zone, including the initialisation of free_lists[]. However populated_zone() checks zone->present_pages to see if a zone has memory available. This is used by iterators such as walk_zones_in_node(). pagetypeinfo_showfree() uses this to walk the free_list of each zone in each node, which are assumed to be initialised due to the zone not being empty. As free_area_init_core() never initialised the free_lists[] this results in the following kernel crash when trying to read /proc/pagetypeinfo: BUG: kernel NULL pointer dereference, address: 0000000000000000 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: 0000 [#1] PREEMPT SMP DEBUG_PAGEALLOC NOPTI CPU: 0 PID: 456 Comm: cat Not tainted 5.16.0 #461 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.14.0-2 04/01/2014 RIP: 0010:pagetypeinfo_show+0x163/0x460 Code: 9e 82 e8 80 57 0e 00 49 8b 06 b9 01 00 00 00 4c 39 f0 75 16 e9 65 02 00 00 48 83 c1 01 48 81 f9 a0 86 01 00 0f 84 48 02 00 00 <48> 8b 00 4c 39 f0 75 e7 48 c7 c2 80 a2 e2 82 48 c7 c6 79 ef e3 82 RSP: 0018:ffffc90001c4bd10 EFLAGS: 00010003 RAX: 0000000000000000 RBX: ffff88801105f638 RCX: 0000000000000001 RDX: 0000000000000001 RSI: 000000000000068b RDI: ffff8880163dc68b RBP: ffffc90001c4bd90 R08: 0000000000000001 R09: ffff8880163dc67e R10: 656c6261766f6d6e R11: 6c6261766f6d6e55 R12: ffff88807ffb4a00 R13: ffff88807ffb49f8 R14: ffff88807ffb4580 R15: ffff88807ffb3000 FS: 00007f9c83eff5c0(0000) GS:ffff88807dc00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000000 CR3: 0000000013c8e000 CR4: 0000000000350ef0 Call Trace: seq_read_iter+0x128/0x460 proc_reg_read_iter+0x51/0x80 new_sync_read+0x113/0x1a0 vfs_read+0x136/0x1d0 ksys_read+0x70/0xf0 __x64_sys_read+0x1a/0x20 do_syscall_64+0x3b/0xc0 entry_SYSCALL_64_after_hwframe+0x44/0xae Fix this by checking that the aligned zone_movable_pfn[] does not exceed the end of the node, and if it does skip creating a movable zone on this node.

Charan Teja Reddy	f47b852faa	ANDROID: implement wrapper for reverse migration ... Reverse migration is used to do the balancing the occupancy of memory zones in a node in the system whose imabalance may be caused by migration of pages to other zones by an operation, eg: hotremove and then hotadding the same memory. In this case there is a lot of free memory in newly hotadd memory which can be filled up by the previous migrated pages(as part of offline/hotremove) thus may free up some pressure in other zones of the node. Upstream discussion: https://lore.kernel.org/all/ee78c83d-da9b-f6d1-4f66-934b7782acfb@codeaurora.org/ Change-Id: Ib3137dab0db66ecf6858c4077dcadb9dfd0c6b1c Bug: 201263307 Signed-off-by: Charan Teja Reddy <quic_charante@quicinc.com>	2022-03-17 21:15:46 +00:00
Suren Baghdasaryan	f03e0cb77b	FROMGIT: mm: count time in drain_all_pages during direct reclaim as memory pressure ... When page allocation in direct reclaim path fails, the system will make one attempt to shrink per-cpu page lists and free pages from high alloc reserves. Draining per-cpu pages into buddy allocator can be a very slow operation because it's done using workqueues and the task in direct reclaim waits for all of them to finish before proceeding. Currently this time is not accounted as psi memory stall. While testing mobile devices under extreme memory pressure, when allocations are failing during direct reclaim, we notices that psi events which would be expected in such conditions were not triggered. After profiling these cases it was determined that the reason for missing psi events was that a big chunk of time spent in direct reclaim is not accounted as memory stall, therefore psi would not reach the levels at which an event is generated. Further investigation revealed that the bulk of that unaccounted time was spent inside drain_all_pages call. A typical captured case when drain_all_pages path gets activated: __alloc_pages_slowpath took 44.644.613ns __perform_reclaim took 751.668ns (1.7%) drain_all_pages took 43.887.167ns (98.3%) PSI in this case records the time spent in __perform_reclaim but ignores drain_all_pages, IOW it misses 98.3% of the time spent in __alloc_pages_slowpath. Annotate __alloc_pages_direct_reclaim in its entirety so that delays from handling page allocation failure in the direct reclaim path are accounted as memory stall.

Andrey Konovalov	bb88568de2	BACKPORT: FROMGIT: kasan, page_alloc: allow skipping memory init for HW_TAGS ... (Backport: adapt the patch to account for added GFP flags and __GFP_BITS_SHIFT definition changes; don't try to pack all flags to avoid macro mess.) Add a new GFP flag __GFP_SKIP_ZERO that allows to skip memory initialization. The flag is only effective with HW_TAGS KASAN. This flag will be used by vmalloc code for page_alloc allocations backing vmalloc() mappings in a following patch. The reason to skip memory initialization for these pages in page_alloc is because vmalloc code will be initializing them instead. With the current implementation, when __GFP_SKIP_ZERO is provided, __GFP_ZEROTAGS is ignored. This doesn't matter, as these two flags are never provided at the same time. However, if this is changed in the future, this particular implementation detail can be changed as well.

The logical condition for calling this function is: - If a software KASAN mode is enabled, we need to mark shadow memory. - Otherwise, HW_TAGS KASAN is enabled, and it only makes sense to set tags if they haven't already been cleared by tag_clear_highpage(), which is indicated by init_tags. This patch concludes the changes for post_alloc_hook().

Andrey Konovalov	55edf5da76	FROMGIT: kasan, page_alloc: deduplicate should_skip_kasan_poison ... Patch series "kasan, vmalloc, arm64: add vmalloc tagging support for SW/HW_TAGS", v6. This patchset adds vmalloc tagging support for SW_TAGS and HW_TAGS KASAN modes. About half of patches are cleanups I went for along the way. None of them seem to be important enough to go through stable, so I decided not to split them out into separate patches/series. The patchset is partially based on an early version of the HW_TAGS patchset by Vincenzo that had vmalloc support. Thus, I added a Co-developed-by tag into a few patches. SW_TAGS vmalloc tagging support is straightforward. It reuses all of the generic KASAN machinery, but uses shadow memory to store tags instead of magic values. Naturally, vmalloc tagging requires adding a few kasan_reset_tag() annotations to the vmalloc code. HW_TAGS vmalloc tagging support stands out. HW_TAGS KASAN is based on Arm MTE, which can only assigns tags to physical memory. As a result, HW_TAGS KASAN only tags vmalloc() allocations, which are backed by page_alloc memory. It ignores vmap() and others. This patch (of 39): Currently, should_skip_kasan_poison() has two definitions: one for when CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled, one for when it's not. Instead of duplicating the checks, add a deferred_pages_enabled() helper and use it in a single should_skip_kasan_poison() definition. Also move should_skip_kasan_poison() closer to its caller and clarify all conditions in the comment.

Baoquan He	e363ab3357	mm/page_alloc.c: do not warn allocation failure on zone DMA if no managed pages ... commit c4dc63f0032c77464fbd4e7a6afc22fa6913c4a7 upstream. In kdump kernel of x86_64, page allocation failure is observed: kworker/u2:2: page allocation failure: order:0, mode:0xcc1(GFP_KERNEL|GFP_DMA), nodemask=(null),cpuset=/,mems_allowed=0 CPU: 0 PID: 55 Comm: kworker/u2:2 Not tainted 5.16.0-rc4+ #5 Hardware name: AMD Dinar/Dinar, BIOS RDN1505B 06/05/2013 Workqueue: events_unbound async_run_entry_fn Call Trace: <TASK> dump_stack_lvl+0x48/0x5e warn_alloc.cold+0x72/0xd6 __alloc_pages_slowpath.constprop.0+0xc69/0xcd0 __alloc_pages+0x1df/0x210 new_slab+0x389/0x4d0 ___slab_alloc+0x58f/0x770 __slab_alloc.constprop.0+0x4a/0x80 kmem_cache_alloc_trace+0x24b/0x2c0 sr_probe+0x1db/0x620 ...... device_add+0x405/0x920 ...... __scsi_add_device+0xe5/0x100 ata_scsi_scan_host+0x97/0x1d0 async_run_entry_fn+0x30/0x130 process_one_work+0x1e8/0x3c0 worker_thread+0x50/0x3b0 ? rescuer_thread+0x350/0x350 kthread+0x16b/0x190 ? set_kthread_struct+0x40/0x40 ret_from_fork+0x22/0x30 </TASK> Mem-Info: ...... The above failure happened when calling kmalloc() to allocate buffer with GFP_DMA. It requests to allocate slab page from DMA zone while no managed pages at all in there. sr_probe() --> get_capabilities() --> buffer = kmalloc(512, GFP_KERNEL | GFP_DMA); Because in the current kernel, dma-kmalloc will be created as long as CONFIG_ZONE_DMA is enabled. However, kdump kernel of x86_64 doesn't have managed pages on DMA zone since commit 6f599d8423 ("x86/kdump: Always reserve the low 1M when the crashkernel option is specified"). The failure can be always reproduced. For now, let's mute the warning of allocation failure if requesting pages from DMA zone while no managed pages.

Baoquan He	240e8d331a	mm_zone: add function to check if managed dma zone exists ... commit 62b3107073646e0946bd97ff926832bafb846d17 upstream. Patch series "Handle warning of allocation failure on DMA zone w/o managed pages", v4. **Problem observed: On x86_64, when crash is triggered and entering into kdump kernel, page allocation failure can always be seen. --------------------------------- DMA: preallocated 128 KiB GFP_KERNEL pool for atomic allocations swapper/0: page allocation failure: order:5, mode:0xcc1(GFP_KERNEL|GFP_DMA), nodemask=(null),cpuset=/,mems_allowed=0 CPU: 0 PID: 1 Comm: swapper/0 Call Trace: dump_stack+0x7f/0xa1 warn_alloc.cold+0x72/0xd6 ...... __alloc_pages+0x24d/0x2c0 ...... dma_atomic_pool_init+0xdb/0x176 do_one_initcall+0x67/0x320 ? rcu_read_lock_sched_held+0x3f/0x80 kernel_init_freeable+0x290/0x2dc ? rest_init+0x24f/0x24f kernel_init+0xa/0x111 ret_from_fork+0x22/0x30 Mem-Info: ------------------------------------ ***Root cause: In the current kernel, it assumes that DMA zone must have managed pages and try to request pages if CONFIG_ZONE_DMA is enabled. While this is not always true. E.g in kdump kernel of x86_64, only low 1M is presented and locked down at very early stage of boot, so that this low 1M won't be added into buddy allocator to become managed pages of DMA zone. This exception will always cause page allocation failure if page is requested from DMA zone. ***Investigation: This failure happens since below commit merged into linus's tree. 1a6a9044b9 x86/setup: Remove CONFIG_X86_RESERVE_LOW and reservelow= options 23721c8e92 x86/crash: Remove crash_reserve_low_1M() f1d4d47c58 x86/setup: Always reserve the first 1M of RAM 7c321eb2b8 x86/kdump: Remove the backup region handling 6f599d8423 x86/kdump: Always reserve the low 1M when the crashkernel option is specified Before them, on x86_64, the low 640K area will be reused by kdump kernel. So in kdump kernel, the content of low 640K area is copied into a backup region for dumping before jumping into kdump. Then except of those firmware reserved region in [0, 640K], the left area will be added into buddy allocator to become available managed pages of DMA zone. However, after above commits applied, in kdump kernel of x86_64, the low 1M is reserved by memblock, but not released to buddy allocator. So any later page allocation requested from DMA zone will fail. At the beginning, if crashkernel is reserved, the low 1M need be locked down because AMD SME encrypts memory making the old backup region mechanims impossible when switching into kdump kernel. Later, it was also observed that there are BIOSes corrupting memory under 1M. To solve this, in commit f1d4d47c58, the entire region of low 1M is always reserved after the real mode trampoline is allocated. Besides, recently, Intel engineer mentioned their TDX (Trusted domain extensions) which is under development in kernel also needs to lock down the low 1M. So we can't simply revert above commits to fix the page allocation failure from DMA zone as someone suggested. ***Solution: Currently, only DMA atomic pool and dma-kmalloc will initialize and request page allocation with GFP_DMA during bootup. So only initializ DMA atomic pool when DMA zone has available managed pages, otherwise just skip the initialization. For dma-kmalloc(), for the time being, let's mute the warning of allocation failure if requesting pages from DMA zone while no manged pages. Meanwhile, change code to use dma_alloc_xx/dma_map_xx API to replace kmalloc(GFP_DMA), or do not use GFP_DMA when calling kmalloc() if not necessary. Christoph is posting patches to fix those under drivers/scsi/. Finally, we can remove the need of dma-kmalloc() as people suggested. This patch (of 3): In some places of the current kernel, it assumes that dma zone must have managed pages if CONFIG_ZONE_DMA is enabled. While this is not always true. E.g in kdump kernel of x86_64, only low 1M is presented and locked down at very early stage of boot, so that there's no managed pages at all in DMA zone. This exception will always cause page allocation failure if page is requested from DMA zone. Here add function has_managed_dma() and the relevant helper functions to check if there's DMA zone with managed pages. It will be used in later patches.

If CMA pages are utilized poorly, non-movable allocations may end up getting starved if all regular movable pages are allocated and the only pages left are CMA. Always using CMA pages first creates unacceptable performance problems. As a midway alternative, use CMA pages for certain userspace allocations. The userspace pages can be migrated or dropped quickly which giving decent utilization. Additionally, add a fall-backs for failed CMA allocations in rmqueue() and __rmqueue_pcplist() (the latter addition being driven by a report by the kernel test robot); these fallbacks were dealt with differently in the original version of the patch as the rmqueue() call chain has changed).

Yang Shi	eac96c3efd	mm: filemap: check if THP has hwpoisoned subpage for PMD page fault ... When handling shmem page fault the THP with corrupted subpage could be PMD mapped if certain conditions are satisfied. But kernel is supposed to send SIGBUS when trying to map hwpoisoned page. There are two paths which may do PMD map: fault around and regular fault. Before commit f9ce0be71d ("mm: Cleanup faultaround and finish_fault() codepaths") the thing was even worse in fault around path. The THP could be PMD mapped as long as the VMA fits regardless what subpage is accessed and corrupted. After this commit as long as head page is not corrupted the THP could be PMD mapped. In the regular fault path the THP could be PMD mapped as long as the corrupted page is not accessed and the VMA fits. This loophole could be fixed by iterating every subpage to check if any of them is hwpoisoned or not, but it is somewhat costly in page fault path. So introduce a new page flag called HasHWPoisoned on the first tail page. It indicates the THP has hwpoisoned subpage(s). It is set if any subpage of THP is found hwpoisoned by memory failure and after the refcount is bumped successfully, then cleared when the THP is freed or split. The soft offline path doesn't need this since soft offline handler just marks a subpage hwpoisoned when the subpage is migrated successfully. But shmem THP didn't get split then migrated at all.

David Hildenbrand	4b09700244	mm: track present early pages per zone ... Patch series "mm/memory_hotplug: "auto-movable" online policy and memory groups", v3. I. Goal The goal of this series is improving in-kernel auto-online support. It tackles the fundamental problems that: 1) We can create zone imbalances when onlining all memory blindly to ZONE_MOVABLE, in the worst case crashing the system. We have to know upfront how much memory we are going to hotplug such that we can safely enable auto-onlining of all hotplugged memory to ZONE_MOVABLE via "online_movable". This is far from practical and only applicable in limited setups -- like inside VMs under the RHV/oVirt hypervisor which will never hotplug more than 3 times the boot memory (and the limitation is only in place due to the Linux limitation). 2) We see more setups that implement dynamic VM resizing, hot(un)plugging memory to resize VM memory. In these setups, we might hotplug a lot of memory, but it might happen in various small steps in both directions (e.g., 2 GiB -> 8 GiB -> 4 GiB -> 16 GiB ...). virtio-mem is the primary driver of this upstream right now, performing such dynamic resizing NUMA-aware via multiple virtio-mem devices. Onlining all hotplugged memory to ZONE_NORMAL means we basically have no hotunplug guarantees. Onlining all to ZONE_MOVABLE means we can easily run into zone imbalances when growing a VM. We want a mixture, and we want as much memory as reasonable/configured in ZONE_MOVABLE. Details regarding zone imbalances can be found at [1]. 3) Memory devices consist of 1..X memory block devices, however, the kernel doesn't really track the relationship. Consequently, also user space has no idea. We want to make per-device decisions. As one example, for memory hotunplug it doesn't make sense to use a mixture of zones within a single DIMM: we want all MOVABLE if possible, otherwise all !MOVABLE, because any !MOVABLE part will easily block the whole DIMM from getting hotunplugged. As another example, virtio-mem operates on individual units that span 1..X memory blocks. Similar to a DIMM, we want a unit to either be all MOVABLE or !MOVABLE. A "unit" can be thought of like a DIMM, however, all units of a virtio-mem device logically belong together and are managed (added/removed) by a single driver. We want as much memory of a virtio-mem device to be MOVABLE as possible. 4) We want memory onlining to be done right from the kernel while adding memory, not triggered by user space via udev rules; for example, this is reqired for fast memory hotplug for drivers that add individual memory blocks, like virito-mem. We want a way to configure a policy in the kernel and avoid implementing advanced policies in user space. The auto-onlining support we have in the kernel is not sufficient. All we have is a) online everything MOVABLE (online_movable) b) online everything !MOVABLE (online_kernel) c) keep zones contiguous (online). This series allows configuring c) to mean instead "online movable if possible according to the coniguration, driven by a maximum MOVABLE:KERNEL ratio" -- a new onlining policy. II. Approach This series does 3 things: 1) Introduces the "auto-movable" online policy that initially operates on individual memory blocks only. It uses a maximum MOVABLE:KERNEL ratio to make a decision whether a memory block will be onlined to ZONE_MOVABLE or not. However, in the basic form, hotplugged KERNEL memory does not allow for more MOVABLE memory (details in the patches). CMA memory is treated like MOVABLE memory. 2) Introduces static (e.g., DIMM) and dynamic (e.g., virtio-mem) memory groups and uses group information to make decisions in the "auto-movable" online policy across memory blocks of a single memory device (modeled as memory group). More details can be found in patch #3 or in the DIMM example below. 3) Maximizes ZONE_MOVABLE memory within dynamic memory groups, by allowing ZONE_NORMAL memory within a dynamic memory group to allow for more ZONE_MOVABLE memory within the same memory group. The target use case is dynamic VM resizing using virtio-mem. See the virtio-mem example below. I remember that the basic idea of using a ratio to implement a policy in the kernel was once mentioned by Vitaly Kuznetsov, but I might be wrong (I lost the pointer to that discussion). For me, the main use case is using it along with virtio-mem (and DIMMs / ppc64 dlpar where necessary) for dynamic resizing of VMs, increasing the amount of memory we can hotunplug reliably again if we might eventually hotplug a lot of memory to a VM. III. Target Usage The target usage will be: 1) Linux boots with "mhp_default_online_type=offline" 2) User space (e.g., systemd unit) configures memory onlining (according to a config file and system properties), for example: * Setting memory_hotplug.online_policy=auto-movable * Setting memory_hotplug.auto_movable_ratio=301 * Setting memory_hotplug.auto_movable_numa_aware=true 3) User space enabled auto onlining via "echo online > /sys/devices/system/memory/auto_online_blocks" 4) User space triggers manual onlining of all already-offline memory blocks (go over offline memory blocks and set them to "online") IV. Example For DIMMs, hotplugging 4 GiB DIMMs to a 4 GiB VM with a configured ratio of 301% results in the following layout: Memory block 0-15: DMA32 (early) Memory block 32-47: Normal (early) Memory block 48-79: Movable (DIMM 0) Memory block 80-111: Movable (DIMM 1) Memory block 112-143: Movable (DIMM 2) Memory block 144-275: Normal (DIMM 3) Memory block 176-207: Normal (DIMM 4) ... all Normal (-> hotplugged Normal memory does not allow for more Movable memory) For virtio-mem, using a simple, single virtio-mem device with a 4 GiB VM will result in the following layout: Memory block 0-15: DMA32 (early) Memory block 32-47: Normal (early) Memory block 48-143: Movable (virtio-mem, first 12 GiB) Memory block 144: Normal (virtio-mem, next 128 MiB) Memory block 145-147: Movable (virtio-mem, next 384 MiB) Memory block 148: Normal (virtio-mem, next 128 MiB) Memory block 149-151: Movable (virtio-mem, next 384 MiB) ... Normal/Movable mixture as above (-> hotplugged Normal memory allows for more Movable memory within the same device) Which gives us maximum flexibility when dynamically growing/shrinking a VM in smaller steps. V. Doc Update I'll update the memory-hotplug.rst documentation, once the overhaul [1] is usptream. Until then, details can be found in patch #2. VI. Future Work 1) Use memory groups for ppc64 dlpar 2) Being able to specify a portion of (early) kernel memory that will be excluded from the ratio. Like "128 MiB globally/per node" are excluded. This might be helpful when starting VMs with extremely small memory footprint (e.g., 128 MiB) and hotplugging memory later -- not wanting the first hotplugged units getting onlined to ZONE_MOVABLE. One alternative would be a trigger to not consider ZONE_DMA memory in the ratio. We'll have to see if this is really rrequired. 3) Indicate to user space that MOVABLE might be a bad idea -- especially relevant when memory ballooning without support for balloon compaction is active. This patch (of 9): For implementing a new memory onlining policy, which determines when to online memory blocks to ZONE_MOVABLE semi-automatically, we need the number of present early (boot) pages -- present pages excluding hotplugged pages. Let's track these pages per zone. Pass a page instead of the zone to adjust_present_page_count(), similar as adjust_managed_page_count() and derive the zone from the page. It's worth noting that a memory block to be offlined/onlined is either completely "early" or "not early". add_memory() and friends can only add complete memory blocks and we only online/offline complete (individual) memory blocks.

After recent updates to freeing unused parts of the memory map, no architecture can have holes in the memory map within a pageblock. This makes pfn_valid_within() check and CONFIG_HOLES_IN_ZONE configuration option redundant. The first patch removes them both in a mechanical way and the second patch simplifies memory_hotplug::test_pages_in_a_zone() that had pfn_valid_within() surrounded by more logic than simple if. This patch (of 2): After recent changes in freeing of the unused parts of the memory map and rework of pfn_valid() in arm and arm64 there are no architectures that can have holes in the memory map within a pageblock and so nothing can enable CONFIG_HOLES_IN_ZONE which guards non trivial implementation of pfn_valid_within(). With that, pfn_valid_within() is always hardwired to 1 and can be completely removed. Remove calls to pfn_valid_within() and CONFIG_HOLES_IN_ZONE.

Dave Hansen	79c28a4167	mm/numa: automatically generate node migration order ... Patch series "Migrate Pages in lieu of discard", v11. We're starting to see systems with more and more kinds of memory such as Intel's implementation of persistent memory. Let's say you have a system with some DRAM and some persistent memory. Today, once DRAM fills up, reclaim will start and some of the DRAM contents will be thrown out. Allocations will, at some point, start falling over to the slower persistent memory. That has two nasty properties. First, the newer allocations can end up in the slower persistent memory. Second, reclaimed data in DRAM are just discarded even if there are gobs of space in persistent memory that could be used. This patchset implements a solution to these problems. At the end of the reclaim process in shrink_page_list() just before the last page refcount is dropped, the page is migrated to persistent memory instead of being dropped. While I've talked about a DRAM/PMEM pairing, this approach would function in any environment where memory tiers exist. This is not perfect. It "strands" pages in slower memory and never brings them back to fast DRAM. Huang Ying has follow-on work which repurposes NUMA balancing to promote hot pages back to DRAM. This is also all based on an upstream mechanism that allows persistent memory to be onlined and used as if it were volatile: http://lkml.kernel.org/r/20190124231441.37A4A305@viggo.jf.intel.com With that, the DRAM and PMEM in each socket will be represented as 2 separate NUMA nodes, with the CPUs sit in the DRAM node. So the general inter-NUMA demotion mechanism introduced in the patchset can migrate the cold DRAM pages to the PMEM node. We have tested the patchset with the postgresql and pgbench. On a 2-socket server machine with DRAM and PMEM, the kernel with the patchset can improve the score of pgbench up to 22.1% compared with that of the DRAM only + disk case. This comes from the reduced disk read throughput (which reduces up to 70.8%). == Open Issues == * Memory policies and cpusets that, for instance, restrict allocations to DRAM can be demoted to PMEM whenever they opt in to this new mechanism. A cgroup-level API to opt-in or opt-out of these migrations will likely be required as a follow-on. * Could be more aggressive about where anon LRU scanning occurs since it no longer necessarily involves I/O. get_scan_count() for instance says: "If we have no swap space, do not bother scanning anon pages" This patch (of 9): Prepare for the kernel to auto-migrate pages to other memory nodes with a node migration table. This allows creating single migration target for each NUMA node to enable the kernel to do NUMA page migrations instead of simply discarding colder pages. A node with no target is a "terminal node", so reclaim acts normally there. The migration target does not fundamentally _need_ to be a single node, but this implementation starts there to limit complexity. When memory fills up on a node, memory contents can be automatically migrated to another node. The biggest problems are knowing when to migrate and to where the migration should be targeted. The most straightforward way to generate the "to where" list would be to follow the page allocator fallback lists. Those lists already tell us if memory is full where to look next. It would also be logical to move memory in that order. But, the allocator fallback lists have a fatal flaw: most nodes appear in all the lists. This would potentially lead to migration cycles (A->B, B->A, A->B, ...). Instead of using the allocator fallback lists directly, keep a separate node migration ordering. But, reuse the same data used to generate page allocator fallback in the first place: find_next_best_node(). This means that the firmware data used to populate node distances essentially dictates the ordering for now. It should also be architecture-neutral since all NUMA architectures have a working find_next_best_node(). RCU is used to allow lock-less read of node_demotion[] and prevent demotion cycles been observed. If multiple reads of node_demotion[] are performed, a single rcu_read_lock() must be held over all reads to ensure no cycles are observed. Details are as follows. === What does RCU provide? === Imagine a simple loop which walks down the demotion path looking for the last node: terminal_node = start_node; while (node_demotion[terminal_node] != NUMA_NO_NODE) { terminal_node = node_demotion[terminal_node]; } The initial values are: node_demotion[0] = 1; node_demotion[1] = NUMA_NO_NODE; and are updated to: node_demotion[0] = NUMA_NO_NODE; node_demotion[1] = 0; What guarantees that the cycle is not observed: node_demotion[0] = 1; node_demotion[1] = 0; and would loop forever? With RCU, a rcu_read_lock/unlock() can be placed around the loop. Since the write side does a synchronize_rcu(), the loop that observed the old contents is known to be complete before the synchronize_rcu() has completed. RCU, combined with disable_all_migrate_targets(), ensures that the old migration state is not visible by the time __set_migration_target_nodes() is called. === What does READ_ONCE() provide? === READ_ONCE() forbids the compiler from merging or reordering successive reads of node_demotion[]. This ensures that any updates are *eventually* observed. Consider the above loop again. The compiler could theoretically read the entirety of node_demotion[] into local storage (registers) and never go back to memory, and *permanently* observe bad values for node_demotion[]. Note: RCU does not provide any universal compiler-ordering guarantees: https://lore.kernel.org/lkml/20150921204327.GH4029@linux.vnet.ibm.com/ This code is unused for now.

Mike Rapoport	c803b3c8b3	mm: introduce memmap_alloc() to unify memory map allocation ... There are several places that allocate memory for the memory map: alloc_node_mem_map() for FLATMEM, sparse_buffer_init() and __populate_section_memmap() for SPARSEMEM. The memory allocated in the FLATMEM case is zeroed and it is never poisoned, regardless of CONFIG_PAGE_POISON setting. The memory allocated in the SPARSEMEM cases is not zeroed and it is implicitly poisoned inside memblock if CONFIG_PAGE_POISON is set. Introduce memmap_alloc() wrapper for memblock allocators that will be used for both FLATMEM and SPARSEMEM cases and will makei memory map zeroing and poisoning consistent for different memory models.

Mike Rapoport	c3ab6baf6a	mm/page_alloc: always initialize memory map for the holes ... Patch series "mm: ensure consistency of memory map poisoning". Currently memory map allocation for FLATMEM case does not poison the struct pages regardless of CONFIG_PAGE_POISON setting. This happens because allocation of the memory map for FLATMEM and SPARSMEM use different memblock functions and those that are used for SPARSMEM case (namely memblock_alloc_try_nid_raw() and memblock_alloc_exact_nid_raw()) implicitly poison the allocated memory. Another side effect of this implicit poisoning is that early setup code that uses the same functions to allocate memory burns cycles for the memory poisoning even if it was not intended. These patches introduce memmap_alloc() wrapper that ensure that the memory map allocation is consistent for different memory models. This patch (of 4): Currently memory map for the holes is initialized only when SPARSEMEM memory model is used. Yet, even with FLATMEM there could be holes in the physical memory layout that have memory map entries. For instance, the memory reserved using e820 API on i386 or "reserved-memory" nodes in device tree would not appear in memblock.memory and hence the struct pages for such holes will be skipped during memory map initialization. These struct pages will be zeroed because the memory map for FLATMEM systems is allocated with memblock_alloc_node() that clears the allocated memory. While zeroed struct pages do not cause immediate problems, the correct behaviour is to initialize every page using __init_single_page(). Besides, enabling page poison for FLATMEM case will trigger PF_POISONED_CHECK() unless the memory map is properly initialized. Make sure init_unavailable_range() is called for both SPARSEMEM and FLATMEM so that struct pages representing memory holes would appear as PG_Reserved with any memory layout.

However, the actual migratetype is preserved in the page and should not be changed to MIGRATE_MOVABLE or the page may end up on the wrong free_list.

Chuck Lever	061478438d	mm/page_alloc: further fix __alloc_pages_bulk() return value ... The author of commit b3b64ebd38 ("mm/page_alloc: do bulk array bounds check after checking populated elements") was possibly confused by the mixture of return values throughout the function. The API contract is clear that the function "Returns the number of pages on the list or array." It does not list zero as a unique return value with a special meaning. Therefore zero is a plausible return value only if @nr_pages is zero or less. Clean up the return logic to make it clear that the returned value is always the total number of pages in the array/list, not the number of pages that were allocated during this call. The only change in behavior with this patch is the value returned if prepare_alloc_pages() fails. To match the API contract, the number of pages currently in the array/list is returned in this case. The call site in __page_pool_alloc_pages_slow() also seems to be confused on this matter. It should be attended to by someone who is familiar with that code.

The page owner code could be audited to strip GFP flags that allow sleeping but it'll impair the functionality of PAGE_OWNER if allocations fail. The bulk allocator could add a special case to release/reacquire the lock for prep_new_page and lookup PCP after the lock is reacquired at the cost of performance. The pages requiring prep could be tracked using the least significant bit and looping through the array although it is more complicated for the list interface. The options are relatively complex and the second one still incurs a performance penalty when PAGE_OWNER is active so this patch takes the simple approach -- disable bulk allocation of PAGE_OWNER is active. The caller will be forced to allocate one page at a time incurring a performance penalty but PAGE_OWNER is already a performance penalty.
