To analyze the hcalls with perf, we need the hcall related tracepoints information to be exported. This patch adds hcall tracepoints "kvm_hv:kvm_hcall_enter" and "kvm_hv:kvm_hcall_exit" to kvm_perf.h. So, perf will now know as to what tracepoints to look for if we are using "perf kvm stat record" to collect guest hcall statistics.
