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().
