mm/hugetlb: fix build failure with HUGETLB_PAGE but not HUGEBTLBFS
[ Upstream commit bb297bb2de517e41199185021f043bbc5d75b377 ]
When CONFIG_HUGETLB_PAGE is set but not CONFIG_HUGETLBFS, the following
build failure is encoutered:
In file included from arch/powerpc/mm/fault.c:33:0:
include/linux/hugetlb.h: In function 'hstate_inode':
include/linux/hugetlb.h:477:9: error: implicit declaration of function 'HUGETLBFS_SB' [-Werror=implicit-function-declaration]
return HUGETLBFS_SB(i->i_sb)->hstate;
^
include/linux/hugetlb.h:477:30: error: invalid type argument of '->' (have 'int')
return HUGETLBFS_SB(i->i_sb)->hstate;
^
Gate hstate_inode() with CONFIG_HUGETLBFS instead of CONFIG_HUGETLB_PAGE.
Fixes: a137e1cc6d6e ("hugetlbfs: per mount huge page sizes")
