Subject: linux-next: slab tree build failure

Hi all,

Today's linux-next build (powerpc ppc64_defconfig) failed like this:

mm/slqb.c:75: error: 'SLAB_GFP_BOOT_MASK' undeclared here (not in a function)

Caused by commit df548b0bbaf2d4d16ce52d2f5ccdc1cfded70e06 ("SLQB: Fix
early boot allocations") from the slab tree interacting with commit
dcce284a259373f9e5570f2e33f79eca84fcf565 ("mm: Extend gfp masking to the
page allocator") that entered Linus' tree today.

I have applied this patch for today:

From: Stephen Rothwell <sfr@...b.auug.org.au>

Subject: [PATCH] slqb: fix for macro name change
