No changes with git version of qemu-kvm
Only see when work guest cpu usage is out of range, about 120% - 150%

Print warning once if pin control bit is set in eventsel msr since
emulation does not support it yet.

If eventsel has EDGE, INV or CMASK set we should create raw counter for
it, but the check is done on a wrong variable. Fix it.

Currently pmu emulation emulates fixed counter 2 as bus cycles
architectural counter, but since commit 9c1497ea591b25d perf has
pseudo encoding for it. Use it.

We can know the guest is paniced when the guest runs on xen.
But we do not have such feature on kvm. This patch implemnts
this feature, and the implementation is the same as xen:
register panic notifier, and call hypercall when the guest
is paniced.
