[PATCH v2] ARM: perf: add guest vs host discrimination

Add minimal guest support to perf, so it can distinguish whether
the PMU interrupt was in the host or the guest, as well as collecting
some very basic information (guest PC, user vs kernel mode).

This is not feature complete though, as it doesn't support backtracing
in the guest.

Based on the x86 implementation, tested with KVM/ARM.

Hi Will,

This is v2 of this patch, based on your perf/updates branch.
If you don't have any additional comment, can you please merge it?

Cheers Marc, I've applied this on top of the same branch and will likely
get it queued for 3.8 (I've already got a fair amount pending for 3.7).

Looking forward to the guest backtracer :)

Will
