This patch syncs contents of tools/include/asm-generic/hugetlb_encode.h and include/uapi/asm-generic/hugetlb_encode.h. Arch powerpc supports 16KB hugepages and ARM64 supports 32MB/512MB hugepages. The corresponding mmap flags have already been added in include/uapi/asm-generic/hugetlb_encode.h, but not tools/include/asm-generic/hugetlb_encode.h.
