Subject: perf: Make EVENT_ATTR global
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2663960c159f23cbfb8e196c96e9fc9f3b5f1a8d;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

perf: Make EVENT_ATTR global

Rename EVENT_ATTR() to PMU_EVENT_ATTR() and make it global so it is
available to all architectures.

Further to allow architectures flexibility, have PMU_EVENT_ATTR() pass
in the variable name as a parameter.

Changelog[v2]
	- [Jiri Olsa] No need to define PMU_EVENT_PTR()
