I think this patch should be ok. There are few direct users of __GFP_HIGH
and some of them are borderline silly (e.g. mm/shmem.c specifying
__GFP_HIGH|__GFP_NOMEMALLOC) while others just look questionable (
drivers/md/raid10.c seems to assume __GFP_HIGH guarantees allocation
success). Xen appears to be the worst abuser of __GFP_HIGH.
