[PATCH 01/20] selftest/powerpc/pmu: Include mmap_buffer field as part of struct event

[Kajol Jain]

From: Athira Rajeev <atraj...@linux.vnet.ibm.com>

To enable the capturing of samples as part of perf event,
add a new field "mmap_buffer" to "struct event". This
field is a place-holder for sample collection
