From f76f5d71048e116f76d2eb02226b01d50890e2f4 Mon Sep 17 00:00:00 2001 From: Nick Piggin Date: Fri, 4 Jun 2010 14:14:51 -0700 Subject: xtensa: invoke oom-killer from page fault As explained in commit 1c0fe6e3bd ("mm: invoke oom-killer from page fault") , we want to call the architecture independent oom killer when getting an unexplained OOM from handle_mm_fault, rather than simply killing current.
