That oops_begin() in generic code is such a layering violation, grrr.

So looking at:

arch/arm/kernel/traps.c:die()

it does call oops_begin() ... oops_end() just like the x86 version of
die().

I'm wondering if we could move the code to do die() in a prepatch? My
assumption is that all the arches should have die()... A quick grep does
show a bunch of other arches having die()...
