[PATCH] powerpc: Make hugepage mappings respect hint addresses
Currently, the powerpc version of hugetlb_get_unmapped_area() entirely
ignores the hint address. The only way to get a hugepage mapping at a
specified address is with MAP_FIXED, in which case there's no way
(short of parsing /proc/self/maps) for userspace to tell if it will
clobber an existing mapping. This is inconvenient, so the patch below
makes hugepage mappings use the given hint address if possible.
