Subject: [RFC PATCH v4 1/9] tools headers: sync headers of asm-generic/hugetlb_encode.h
Date: Tue, 2 Mar 2021 20:57:43 +0800 [thread overview]
Message-ID: <20210302125751.19080-2-wangyanan55@huawei.com> (raw)
In-Reply-To: <20210302125751.19080-1-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.
