The patch titled hugetlb-add-map_hugetlb-for-mmaping-pseudo-anonymous-huge-page-regionspatch-in-mm-fix has been removed from the -mm tree. Its filename was hugetlb-add-map_hugetlb-for-mmaping-pseudo-anonymous-huge-page-regionspatch-in-mm-fix.patch This patch was dropped because it is obsolete The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: hugetlb-add-map_hugetlb-for-mmaping-pseudo-anonymous-huge-page-regionspatch-in-mm-fix From: Eric B Munson <ebmunson@xxxxxxxxxx> The patch hugetlb-add-map_hugetlb-for-mmaping-pseudo-anonymous-huge-page-regions.patch used the value 0x40 for MAP_HUGETLB which is the same value used for various other flags on some architectures. This collision causes unexpected use of huge pages in the best case and mmap to fail with ENOMEM or ENOSYS in the worst. This patch changes the value for MAP_HUGETLB to a value that is not currently used on any arch. This patch should be considered a fix to hugetlb-add-map_hugetlb-for-mmaping-pseudo-anonymous-huge-page-regions.patch.
