I will test this patch, but it doesn't apply cleanly to the version of Xen I'm 
currently using, so I need to update that first.

I also looked at whether it would be possible to set the CNTFRQ register in the 
other cores when they come up. Eventually, I think we should do this in the 
(platform-specific) PSCI code. There doesn't seem to be a suitable hook in the 
platform-specific Xen code - it looks like all the code there related to 
bringing up secondary cores runs on the primary.
