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.

Commit e201260081 ("arm64: perf: Add userspace counter access disable
switch") introduced a new 'perf_user_access' sysctl file to enable and
disable direct userspace access to the PMU counters. Sadly, Geert
reports that on his big.LITTLE SoC ('Renesas Salvator-XS w/ R-Car H3'),
the file is created for each PMU type probed, resulting in a splat
during boot:

Introduce a state variable to track creation of the sysctl file and

Since internal_flags is only 8 bits, we can only have one
more internal flag. However, we can obviously never use all
of possible the combinations, in fact, we only use 14 of
them (including no flags).
Since we want more flags for MLO (multi-link operation) in
the future, refactor the code to use a flags selector, so
wrap all of the .internal_flags assignments in a IFLAGS()
macro which selects the combination according to the pre-
defined list of combinations.
When we need a new combination, we'll have to add it, but
again we will never use all possible combinations.

Some of the irq migration paths call chip set affinity, after
current CPU is marked offline in cpu_online_mask. These
chip set affinity calls do not invoke vendor trace hooks.
So, convert gic_v3_set_affinity() vendor hook to a restricted
hook, to allow trace hook to be called from these irq migration
paths.

In file included from <built-in>:1:
./usr/include/linux/icmp.h:100:3: warning: declaration does not declare
anything [-Wmissing-declarations]

^~~~~~
This is because Bionic defines __unused to expand to
__attribute__((__unused__)). Bionic pre-processes kernel headers and
redefines __unused to __linux_unused.
Do so here to avoid issues that only appear for Bionic based sysroot
UAPI header tests.

When a file-backed vma is being released, the userspace can have an
expectation that the vma and the file it's pinning will be released
synchronously. This does not happen when SPF is enabled because vma
and associated file are released asynchronously after RCU grace
period. This is done to prevent pagefault handler from stepping on
a deleted object. Fix this issue by synchronizing the file-backed
pagefault handler with the vma tear-down using notifier lock.
