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

[Stephen Rothwell]

Hi Andrew,

After merging the akpm tree, today's linux-next build (arm multi_v7_defconfig)
produced this warning:

In file included from include/linux/mm.h:52:0,
                 from mm/gup.c:7:
arch/arm/include/asm/pgtable.h:184:0: warning: "pgd_huge" redefined
 #define pgd_huge(pgd)  (0)
 ^
In file included from mm/gup.c:6:0:
include/linux/hugetlb.h:183:0: note: this is the location of the previous definition
 #define pgd_huge(x) 0
 ^

Introduced by commit fee025d5dd4e ("mm: update generic gup
implementation to handle hugepage directory").
