Chris Goldsworthy 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().
