For some reason v1 didn't make it to linux-mm; let's see if the problem
persists.

Let's clean up the gfp flags handling, and support __GFP_ZERO, such that we
can finally remove the TODO in memtrace code.

I did some alloc_contig_*() testing with virtio-mem and hugetlb; I did not
test powernv/memtrace -- I cross-compiled it, though.

v1 -> v2:
* "mm/page_alloc: forward the gfp flags from alloc_contig_range() to
   post_alloc_hook()"
