From: Peter Griffin <peter.griffin@linaro.org>

The site specific OOM messages are unncessary, because they duplicate
messages from the memory subsystem which include dump_stack().

Removing these superflous messages makes the kernel smaller. A discussion
here http://patchwork.ozlabs.org/patch/324158/ found that all error paths
from kzalloc will print a error message, and that any error path which maybe
found which doesn't would be considered a bug in kzalloc.
