David Rientjes 1b604d75bb oom: dump stack and VM state when oom killer panics 
The oom killer header, including information such as the allocation order
and gfp mask, current's cpuset and memory controller, call trace, and VM
state information is currently only shown when the oom killer has selected
a task to kill.

This information is omitted, however, when the oom killer panics either
because of panic_on_oom sysctl settings or when no killable task was
found.  It is still relevant to know crucial pieces of information such as
the allocation order and VM state when diagnosing such issues, especially
at boot.

This patch displays the oom killer header whenever it panics so that bug
reports can include pertinent information to debug the issue, if possible.
