[PATCH v6 2/2] perf,kvm/powerpc: Add hcall related info to kvm_perf.h

From: Hemant Kumar
Date: Mon Aug 31 2015 - 02:48:17 EST

To analyze the hcalls with perf kvm stat, we need the hcall related
tracepoint 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 to look
for these tracepoints if "perf kvm stat record" is invoked to collect
guest hcall statistics.
