Subject: [patch 10/14] parisc: invoke oom-killer from page fault
Date: Fri, 23 Apr 2010 02:06:23 +1000	[thread overview]
Message-ID: <20100422161224.322033236@suse.de> (raw)
In-Reply-To: 20100422160613.723698029@suse.de

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.
