[Intel-gfx] [PATCH v4 7/9] parisc/perf: open access for CAP_SYS_PERFMON privileged process

[Alexey Budankov]

Open access to monitoring for CAP_SYS_PERFMON privileged processes.
For backward compatibility reasons access to the monitoring remains open
for CAP_SYS_ADMIN privileged processes but CAP_SYS_ADMIN usage for secure
monitoring is discouraged with respect to CAP_SYS_PERFMON capability.
