This patch introduces a new default FIQ handler that is structured in a similar way to the existing ARM exception handler and result in the FIQ being handled by C code running on the SVC stack (despite this code run in the FIQ handler is subject to severe limitations with respect to locking making normal interaction with the kernel impossible).
This default handler allows concepts that on x86 would be handled using NMIs to be realized on ARM.

This patch is a near complete re-write of a patch originally provided by Anton Vorontsov. Today only a couple of small fragments survive, however without Anton's work to build from this patch would not exist. Thanks also to Russell King for spoonfeeding me a variety of fixes during the review cycle.I've send this patch to the your patch tracker as complete respin (#8150/2).
If you'd rather handle it as a follow on patch please let me know and I will prepare it as one.
Thanks, as you will see, I've merged this patch, along with my two patches, one removing do_unexp_fiq() and the newline removal in show_regs(). They should be appearing in a linux-next rsn.
