[PATCH v2 1/3] perf kvm: Introduce evsel as argument to perf_event__preprocess_sample

From: Ravi Bangoria
Date: Fri Jan 22 2016 - 00:59:46 EST


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.
