  "message": "[PATCH] KVM: fix bogus pagefault on writable pages\n\nIf a page is marked as dirty in the guest pte, set_pte_common() can set the\nwritable bit on newly-instantiated shadow pte.  This optimization avoids\na write fault after the initial read fault.\n\nHowever, if a write fault instantiates the pte, fix_write_pf() incorrectly\nreports the fault as a guest page fault, and the guest oopses on what appears\nto be a correctly-mapped page.\n\nFix is to detect the condition and only report a guest page fault on a user\naccess to a kernel page.\n\nWith the fix, a kvm guest can survive a whole night of running the kernel\nhacker\u0027s screensaver (make -j9 in a loop).\n\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
