Currently perf-kvm uses string literals for kvm event names, but it works only for x86, because other architectures may have other names for those events. To reduce dependence on architecture, we add <asm/kvm_perf.h> file with defines for: - kvm_entry and kvm_exit events, - exit reason field name in kvm_exit event, - length of exit reasons strings, - vcpu_id field name in kvm trace events, and replace literals in perf-kvm.
