HWPOISON: Add poison check to page fault handling Bail out early when hardware poisoned pages are found in page fault handling. Since they are poisoned they should not be mapped freshly into processes, because that would cause another (potentially deadly) machine check This is generally handled in the same way as OOM, just a different error code is returned to the architecture code. v2: Do a page unlock if needed (Fengguang Wu) Signed-off-by: Andi Kleen <ak@linux.intel.com>
