int the commit: https://android-review.googlesource.com/c/kernel/common/+/1699406/
When we build our vendor driver, report two errors:
1) Symbol too long "trace_android_vh_get_unmapped_area_from_anti_fragment_pool"
2) Symbol too long "trace_android_vh_get_unmapped_area_include_reserved_zone"
So, I shorten the function names:
android_vh_get_unmapped_area_from_anti_fragment_pool --> android_vh_get_from_fragment_pool
android_vh_get_unmapped_area_include_reserved_zone --> android_vh_include_reserved_zone

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.

When running 32-bit apps for a long time, virtual address becomes fragmented which can lead to allocation failures when a large virtually-contiguous area is requested.
Add hooks to implement pools to cluster together small-sized virtual address mappings.
Add hooks to implement reserved virtual address zone with usage restrictions controlled by vendor hooks.
These hooks help in controlling virtual address space fragmentation.

Remove macro versions of hooks that are no longer needed. The
macro versions are still needed when the _rcuidle version

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().
