Subject: [PATCH v2 1/3] perf kvm: Introduce evsel as argument to perf_event__preprocess_sample
This patch changes prototype of perf_event__preprocess_sample() with
additional argument evsel added at last.
This change is required because perf_event__preprocess_sample()
function will use evsel to determine cpumode of samples for powerpc
architecture.
Signed-off-by: Ravi Bangoria <ravi.bangoria@...ux.vnet.ibm.com>
