Note that this is for warnings, not oopses.

This comment in oops_enter threw me off of using it:

        debug_locks_off(); /* can't trust the integrity of the kernel
	anymore */

Since we can very well depend on the integrity of the kernel when it's
just doing a __WARN().

do_warn_slowpath() doesn't use oops_enter() either.
