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.
