From 67a8a20fe1eec43ebfa7f2b83e988dbdb4c16271 Mon Sep 17 00:00:00 2001 From: Nick Piggin Date: Mon, 9 Aug 2010 17:19:02 -0700 Subject: avr32: 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.
