Subject: [patch 02/14] avr32: invoke oom-killer from page fault
Date: Fri, 23 Apr 2010 02:06:15 +1000	[thread overview]
Message-ID: <20100422161222.953856396@suse.de> (raw)
In-Reply-To: 20100422160613.723698029@suse.de

[-- Attachment #1: avr32-pagefault-use-oom.patch --]
[-- Type: text/plain, Size: 911 bytes --]

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.
