(cherry picked from commit 878e0caa77)
Provide a vendor hook to skip cma-pages to add in pcplist when
free_unref_page_commit.
The patch is revelant to skip drain_all_pages in alloc_contig_range,
the revelant hooks is android_vh_cma_drain_all_pages_bypass
which is to avoid to delay in drain pcppages when drain_all_pages.
In most case, pcp->high is small so that free-pages with other mt_types
can also fill with pcplist full.

Provide a vendor hook to allow drain_all_pages to be skipped
during alloc_contig_range in some cases to avoid delays caused by
it in cases when the benefits of draining pcp lists are known
to be small.

When vendor hooks are added to a file that previously didn't have any
vendor hooks, we end up indirectly including linux/tracepoint.h. This
causes some data types that used to be opaque (forward declared) to the
code to become visible to the code.
Modversions correctly catches this change in visibility, but we don't
really care about the data types made visible when linux/tracepoint.h is
included. So, hide this from modversions in the central vendor_hooks.h file
instead of having to fix this on a case by case basis.
This change itself will cause a one time CRC breakage/churn because it's
fixing the existing vendor hook headers, but should reduce unnecessary CRC
churns in the future.
To avoid future pointless CRC churn, vendor hook header files that include
vendor_hooks.h should not include linux/tracepoint.h directly.

In some cases we would like to bypass oom panic and give the system more
time to cleanup memory. Add vendor hook to allow skipping the oom panic.

Remove macro versions of hooks that are no longer needed. The
macro versions are still needed when the _rcuidle version
of the hook is used (as in include/trace/hooks/debug.h).

Create a vendor hook inside of gfp_zone() to modify which allocations
get to enter ZONE_MOVABLE, by zeroing out __GFP_HIGHMEM inside of the
trace hook based on certain conditions.
Separately, create separate trace hooks in the swap-in and readahead
paths to affect the behavior of the tracehook in gfp_zone().
