ARM: 7424/1: update die handler from x86
Robustify ARM's die() handling with improvements from x86:
- Fix for a deadlock (before panic in the case of panic_on_oops) if we
oops under a spinlock which is also used from interrupt handler,
since the old code was unconditionally enabling interrupts.
- Usage of arch spinlock so lockdep etc doesn't get involved while
we're trying to dump out oopses.
- Deadlock prevention in the unlikely event that die() recurses.
The changes all touch the same few lines of code, so they're done
together in one patch.
