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

From: Kajol Jain <[email-masked]>
Date: Thu, 27 Jan 2022 12:49:53 +0530

From: Athira Rajeev <[email-masked]>

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
