Set of fixes to KVM's handling of the exception level event filtering in the PMU event type registers. I dropped the PMU+NV disablement this time around as we need a complete fix for that problem. At the same time, I want to get a rework of our sysreg masks upstream soon to avoid any negative interaction with new PMU features going in on the driver side of things. Additionally, I added a fix for the non-secure filtering bits that Suzuki had spotted (thanks!)
