Peter Zijlstra 2565711fb7 perf: Improve the perf_sample_data struct layout
This patch reorders fields in the perf_sample_data struct in order to
minimize the number of cachelines touched in perf_sample_data_init().
It also removes some intializations which are redundant with the code
in kernel/events/core.c
