A patch upstream landed on 2011-12-6 that reduces the mmap_sem hold time, which is crucial during OOM killer invocation. It would be very beneficial if this patch could get pulled into all supported arm precise kernels.
See http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=7178/1 for details on the patch. The upstream git commit is http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=8878a539ff19a43cf3729e7562cd528f490246ae
I have attached the raw patch as well for review.
