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.

10fc8b2584 ANDROID: simplify vendor hook definitions 
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).

62e32cf8f3 ANDROID: mm: Create vendor hooks to control ZONE_MOVABLE allocations 
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().
