Subject: [PATCH v5 1/2] perf,kvm/ppc: Add kvm_perf.h for powerpc
To analyze the exit events with perf, we need kvm_perf.h to be added in
the arch/powerpc directory, where the kvm tracepoints needed to trace
the KVM exit events are defined.
This patch adds "kvm_perf_book3s.h" to indicate that the tracepoints are
book3s specific. Generic "kvm_perf.h" then can just include
"kvm_perf_book3s.h".
Signed-off-by: Hemant Kumar <hemant@...ux.vnet.ibm.com>

Changes:
- Not exporting the exit reasons compared to previous patchset (suggested by Paul)
