82654b6b8e nvme: fix hang in remove path
We need to start admin queues too in nvme_kill_queues()
for avoiding hang in remove path[1].

This patch is very similar with 806f026f9b901eaf(nvme: use
blk_mq_start_hw_queues() in nvme_kill_queues()).

In a previous commit, tracepoints are added for PCM parameter processing.
As long as I know, this implementation increases size of relocatable

be4e31dab0 ALSA: pcm: tracepoints for refining PCM parameters
When working for devices which support configurable modes for its data
transmission or which consists of several components, developers are
likely to use rules of parameters of PCM substream. However, there's no
infrastructure to assist their work.

In old days, ALSA PCM core got a local 'RULES_DEBUG' macro to debug
refinement of parameters for PCM substream. Although this is merely a
makeshift. With some modifications, we get the infrastructure.

This commit is for the purpose. Refinement of mask/interval type of
PCM parameters is probed as tracepoint events as 'hw_mask_param' and
'hw_interval_param' on existent 'snd_pcm' subsystem.

d7f910bfed ALSA: timer: Wrap with spinlock for queue access
For accessing the snd_timer_user queue indices, we take tu->qlock.
But it's forgotten in a couple of places.

The one in snd_timer_user_params() should be safe without the
spinlock as the timer is already stopped.  But it's better for
consistency.

The one in poll is just a read-out, so it's not inevitably needed, but
it'd be good to make the result consistent, too.

890e2cb5d1 ALSA: timer: Improve user queue reallocation
ALSA timer may reallocate the user queue upon request, and it happens
at three places for now: at opening, at SNDRV_TIMER_IOCTL_PARAMS, and
at SNDRV_TIMER_IOCTL_SELECT.  However, the last one,
snd_timer_user_tselect(), doesn't need to reallocate the buffer since
it doesn't change the queue size.  It does just because tu->tread
might have been changed before starting the timer.

Instead of *_SELECT ioctl, we should reallocate the queue at
SNDRV_TIMER_IOCTL_TREAD; then the timer is guaranteed to be stopped,
thus we can reassign the buffer more safely.

This patch implements that with a slight code refactoring.
Essentially, the patch achieves:
- Introduce realloc_user_queue() for (re-)allocating the ring buffer,
  and call it from all places.  Also, realloc_user_queue() uses
  kcalloc() for avoiding possible leaks.
- Add the buffer reallocation at SNDRV_TIMER_IOCTL_TREAD.  When it
  fails, tu->tread is restored to the old value, too.
- Drop the buffer reallocation at snd_timer_user_tselect().

ba3021b2c7 ALSA: timer: Fix missing queue indices reset at SNDRV_TIMER_IOCTL_SELECT
snd_timer_user_tselect() reallocates the queue buffer dynamically, but
it forgot to reset its indices.  Since the read may happen
concurrently with ioctl and snd_timer_user_tselect() allocates the
buffer via kmalloc(), this may lead to the leak of uninitialized
kernel-space data, as spotted via KMSAN:

d11662f4f7 ALSA: timer: Fix race between read and ioctl
The read from ALSA timer device, the function snd_timer_user_tread(),
may access to an uninitialized struct snd_timer_user fields when the
read is concurrently performed while the ioctl like
snd_timer_user_tselect() is invoked.  We have already fixed the races
among ioctls via a mutex, but we seem to have forgotten the race
between read vs ioctl.

This patch simply applies (more exactly extends the already applied
range of) tu->ioctl_lock in snd_timer_user_tread() for closing the
race window.

875becf841 ALSA: firewire: process packets in 'struct snd_pcm_ops.ack' callback
In recent commit for ALSA PCM core, some arrangement is done for
'struct snd_pcm_ops.ack' callback. This is called when appl_ptr is
explicitly moved in intermediate buffer for PCM frames, except for
some cases described later.

For drivers in ALSA firewire stack, usage of this callback has a merit to
reduce latency between time of PCM frame queueing and handling actual
packets in recent isochronous cycle, because no need to wait for software
IRQ context from isochronous context of OHCI 1394.

If this works well in a case that mapped page frame is used for the
intermediate buffer, user process should execute some commands for ioctl(2)
to tell the number of handled PCM frames in the intermediate buffer just
after handling them. Therefore, at present, with a combination of below
conditions, this doesn't work as expected and user process should wait for
the software IRQ context as usual:
 - when ALSA PCM core judges page frame mapping is available for status
   data (struct snd_pcm_mmap_status) and control data
   (struct snd_pcm_mmap_control).
 - user process handles PCM frames by loop just with 'snd_pcm_mmap_begin()'
   and 'snd_pcm_mmap_commit()'.
 - user process uses PCM hw plugin in alsa-lib to operate I/O without
   'sync_ptr_ioctl' option.

Unfortunately, major use case include these three conditions.

Russell King says:

====================
net: Add phylib support for MV88X3310 10G phy

This patch series adds support for the Marvell 88x3310 PHY found on
the SolidRun Macchiatobin board.

The first patch introduces a set of generic Clause 45 PHY helpers that
C45 PHY drivers can make use of if they wish.

Patch 2 ensures that the Clause 22 aneg_done function will not be
called for incompatible Clause 45 PHYs.

Patch 3 fixes the aneg restart to be compatible with C45 PHYs - it can
currently only cope with C22 PHYs.

Patch 4 moves the "gen10g" driver into the Clause 45 code, grouping all
core clause 45 code together.

Patch 5 adds the phy_interface_t types for XAUI and 10GBase-KR links.
As 10GBase-KR appears to be compatible with XFI and SFI, XFI and SFI,
I currently see no reason to add XFI and SFI interface modes.  There
seems to be vendor code out there using these, but they all alias back
to the same hardware settings.

Patch 6 adds support for the MV88X3310 PHY, which supports both the
copper and fiber interfaces.  It should be noted that the MV88X3310
automatically switches its MAC facing interface between 10GBase-KR
and SGMII depending on the negotiated speed.  This was discussed with
Florian, and we agreed to update the phy interface mode depending on
the properties of the actual link mode to the PHY.

v2:
- update sysfs-class-net-phydev documentation
- avoid genphy_aneg_done for non-C22 PHYs
- expand comment about 0x30 constant
- add comment about lack of reset
- configure driver using MARVELL_10G_PHY

20b2af32ff net: phy: add Marvell Alaska X 88X3310 10Gigabit PHY support
Add phylib support for the Marvell Alaska X 10 Gigabit PHY (MV88X3310).
This phy is able to operate at 10G, 1G, 100M and 10M speeds, and only
supports Clause 45 accesses.

The PHY appears (based on the vendor IDs) to be two different vendors
IP, with each devad containing several instances.

This PHY driver has only been tested with the RJ45 copper port, fiber
port and a Marvell Armada 8040-based ethernet interface.

It should be noted that to use the full range of speeds, MAC drivers
need to also reconfigure the link mode as per phydev->interface, since
the PHY automatically changes its interface mode depending on the
negotiated speed.

10GBASE-KR is a single lane Serdes backplane ethernet connection method
with autonegotiation on the link.  Some PHYs use this to connect to the
ethernet interface at 10G speeds, switching to other connection types
when utilising slower speeds.

10GBASE-KR is also used for XFI and SFI to connect to XFP and SFP fiber
modules.

41408ad519 net: phy: avoid genphy_aneg_done() for PHYs without clause 22 support
Avoid calling genphy_aneg_done() for PHYs that do not implement the
Clause 22 register set.

Clause 45 PHYs may implement the Clause 22 register set along with the
Clause 22 extension MMD.  Hence, we can't simply block access to the
Clause 22 functions based on the PHY being a Clause 45 PHY.

f3b7eaae1b Revert "ACPI / sleep: Ignore spurious SCI wakeups from suspend-to-idle"
Revert commit eed4d47efe (ACPI / sleep: Ignore spurious SCI wakeups
from suspend-to-idle) as it turned out to be premature and triggered
a number of different issues on various systems.

That includes, but is not limited to, premature suspend-to-RAM aborts
on Dell XPS 13 (9343) reported by Dominik.

The issue the commit in question attempted to address is real and
will need to be taken care of going forward, but evidently more work
is needed for this purpose.

abb2ea7dfd compiler, clang: suppress warning for unused static inline functions
GCC explicitly does not warn for unused static inline functions for
-Wunused-function.  The manual states:

	Warn whenever a static function is declared but not defined or
	a non-inline static function is unused.

Clang does warn for static inline functions that are unused.

It turns out that suppressing the warnings avoids potentially complex
#ifdef directives, which also reduces LOC.

Suppress the warning for clang.

a7049de1e8 drm/amdgpu/gfx9: new queue policy, take first 2 queues of each pipe
Instead of taking the first pipe and giving the rest to kfd, take the
first 2 queues of each pipe.

Effectively, amdgpu and amdkfd own the same number of queues. But
because the queues are spread over multiple pipes the hardware will be
able to better handle concurrent compute workloads.

amdgpu goes from 1 pipe to 4 pipes, i.e. from 1 compute threads to 4
amdkfd goes from 3 pipe to 4 pipes, i.e. from 3 compute threads to 4

gfx9 was missed when this patch set was rebased to include gfx9.

1361f45531 drm/amdgpu/gfx9: allocate queues horizontally across pipes
Pipes provide better concurrency than queues, therefore we want to make
sure that apps use queues from different pipes whenever possible.

Optimize for the trivial case where an app will consume rings in order,
therefore we don't want adjacent rings to belong to the same pipe.

gfx9 was missed when these patches were rebased.
