Subject: [RFC PATCH v2 1/7] tools include: sync head files of mmap flag encodings about hugetlb
Date: Thu, 25 Feb 2021 13:59:34 +0800	[thread overview]
Message-ID: <20210225055940.18748-2-wangyanan55@huawei.com> (raw)
In-Reply-To: <20210225055940.18748-1-wangyanan55@huawei.com>

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.
