From adbf6e6952e80ae42a403442dcae21438cae94b3 Mon Sep 17 00:00:00 2001 From: Nick Piggin Date: Fri, 23 Apr 2010 02:06:20 +1000 Subject: [PATCH] m68k: 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.
