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.
