From 21e1c93631e027136ea4070e7bca600c4ad4f391 Mon Sep 17 00:00:00 2001 From: Nick Piggin Date: Fri, 23 Apr 2010 02:06:21 +1000 Subject: [PATCH] microblaze: 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.
