Subject: Re: [PATCH 7/8] Use GFP_OTHER_NODE for transparent huge pages

This fixes build with CONFIG_NUMA=n for patch 7 (noticed on my
laptop which isn't NUMA yet ;).

Subject: thp: add extra_gfp in alloc_hugepage non NUMA

From: Andrea Arcangeli <aarcange@...hat.com>

Add extra_gfp to avoid build failure with CONFIG_NUMA=n.
