  "message": "x86/mm: Introduce pte_accessible()\n\nWe need pte_present to return true for _PAGE_PROTNONE pages, to indicate that\nthe pte is associated with a page.\n\nHowever, for TLB flushing purposes, we would like to know whether the pte\npoints to an actually accessible page.  This allows us to skip remote TLB\nflushes for pages that are not actually accessible.\n\nFill in this method for x86 and provide a safe (but slower) method\non other architectures.\n\nSigned-off-by: Rik van Riel \u003criel@redhat.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nFixed-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLink: http://lkml.kernel.org/n/tip-66p11te4uj23gevgh4j987ip@git.kernel.org\n[ Added Linus\u0027s review fixes. ]\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\n",
