72488b3be4 ANDROID: mm, oom: add vendor hook to prevent oom panic 
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.

dc5241048f ANDROID: vendor_hooks: Add hooks for reducing virtual address fragmentation 
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.

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().
