Vince Weaver	2cc9e588b0	arc, perf: Use common PMU interrupt disabled code ... Transition to using the new generic PERF_PMU_CAP_NO_INTERRUPT method for failing a sampling event when no PMU interrupt is available.

Mischa Jonker	230c4aadcc	ARC: perf: ARC 700 PMU doesn't support sampling events ... The ARC 700 does not have an interrupt associated with it, and as such it cannot trigger when a counter overflows. As the counters are 48 bit, it will usually take at least 100 days before a counter overflows, so for mere counting of events, there is no problem. Sampling is not supported though.

Mischa Jonker	0dd450fe13	ARC: Add perf support for ARC700 cores ... This adds basic perf support for ARC700 cores. Most PERF_COUNT_HW* events are supported now.
