[PATCH 04/10] oom: move sysctl declarations to oom.h

[KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com>]

From: David Rientjes <rientjes@google.com>

The three oom killer sysctl variables (sysctl_oom_dump_tasks,
sysctl_oom_kill_allocating_task, and sysctl_panic_on_oom) are better
declared in include/linux/oom.h rather than kernel/sysctl.c.
