Subject: linux-next: build failure after merge of the akpm-current tree

Hi all,

After merging the akpm-current tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

ld: lib/ioremap.o: in function `.ioremap_huge_init':
ioremap.c:(.init.text+0x3c): undefined reference to `.arch_ioremap_p4d_supported'

Caused by commit

  749940680d0b ("mm/ioremap: probe platform for p4d huge map support")

I have reverted that commit for today.
