There\u0027s just a misleading comment\nfor the __range_not_ok() macro - which this patch fixes as well.\n\nThe last page of the user-space address range is a guard page and\nBrian Gerst observed that the guard page itself due to an erratum on K8 cpus\n(#121 Sequential Execution Across Non-Canonical Boundary Causes Processor\nHang).\n\nHowever, the test code is using the last valid page before the guard page.\nThe bug is that the last byte before the guard page can\u0027t be read\nbecause of the off-by-one error. The guard page is left in place.\n\nThis bug would normally not show up because the last page is\npart of the process stack and never accessed via syscalls.\n\nSigned-off-by: Jiri Olsa \u003cjolsa@redhat.com\u003e\nAcked-by: Brian Gerst \u003cbrgerst@gmail.com\u003e\nAcked-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: \u003cstable@kernel.org\u003e\nLink: http://lkml.kernel.org/r/1305210630-7136-1-git-send-email-jolsa@redhat.com\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "2f19e06ac30771c7cb96fd61d8aeacfa74dac21c", "tree": "00a13ef37681e1f983a40680b17c850ce035fb87", "parents": [ "057e05c1d6440117875f455e59da8691e08f65d5" ], "author": { "name": "Fenghua Yu", "email": "fenghua.yu@intel.com", "time": "Tue May 17 15:29:18 2011 -0700" }, "committer": { "name": "H.
