[GIT PULL] ARM perf updates for 3.3

[Russell King - ARM Linux]

Tony,

Can you please treat this with the utmost urgency.  If I don't get a
reply from you within the next two hours, then I'm committing this
merge resolution whether or not it's correct for you - as I have other
stuff which needs to be committed to my tree and I can't wait any
longer for your reply.

Thanks.
