Wei Huang	b6bb424b40	KVM: x86/vPMU: Fix unnecessary signed extension for AMD PERFCTRn ... According to AMD programmer's manual, AMD PERFCTRn is 64-bit MSR which, unlike Intel perf counters, doesn't require signed extension. This patch removes the unnecessary conversion in SVM vPMU code when PERFCTRn is being updated.

Wei Huang	25462f7f52	KVM: x86/vPMU: Define kvm_pmu_ops to support vPMU function dispatch ... This patch defines a new function pointer struct (kvm_pmu_ops) to support vPMU for both Intel and AMD. The functions pointers defined in this new struct will be linked with Intel and AMD functions later. In the meanwhile the struct that maps from event_sel bits to PERF_TYPE_HARDWARE events is renamed and moved from Intel specific code to kvm_host.h as a common struct.
