From 0c3b96e44739cdba7a75030107a2b47a15ee5f60 Mon Sep 17 00:00:00 2001 From: "npiggin@suse.de" Date: Fri, 7 May 2010 14:34:33 -0700 Subject: [PATCH] [IA64] invoke oom-killer from page fault As explained in commit 1c0fe6e3bd, we want to call the architecture independent oom killer when getting an unexplained OOM from handle_mm_fault, rather than simply killing current.
