      "message": "[PATCH] Enable mprotect on huge pages\n\n2.6.16-rc3 uses hugetlb on-demand paging, but it doesn_t support hugetlb\nmprotect.\n\nFrom: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\n\n  Remove a test from the mprotect() path which checks that the mprotect()ed\n  range on a hugepage VMA is hugepage aligned (yes, really, the sense of\n  is_aligned_hugepage_range() is the opposite of what you\u0027d guess :-/).\n\n  In fact, we don\u0027t need this test.  If the given addresses match the\n  beginning/end of a hugepage VMA they must already be suitably aligned.  If\n  they don\u0027t, then mprotect_fixup() will attempt to split the VMA.  The very\n  first test in split_vma() will check for a badly aligned address on a\n  hugepage VMA and return -EINVAL if necessary.\n\nFrom: \"Chen, Kenneth W\" \u003ckenneth.w.chen@intel.com\u003e\n\n  On i386 and x86-64, pte flag _PAGE_PSE collides with _PAGE_PROTNONE.  The\n  identify of hugetlb pte is lost when changing page protection via mprotect.\n  A page fault occurs later will trigger a bug check in huge_pte_alloc().\n\n  The fix is to always make new pte a hugetlb pte and also to clean up\n  legacy code where _PAGE_PRESENT is forced on in the pre-faulting day.\n\nSigned-off-by: Zhang Yanmin \u003cyanmin.zhang@intel.com\u003e\nCc: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nCc: \"David S.
