[S390] perf: add support for s390x CPU counters
Add a perf PMU to access the CPU-measurement counter facility CPUM CF. CPUM CF provides multiple counter sets for measuring generic, problem-state, and crypto activaties. Also an extended counter set for the IBM System z10 and IBM z196 mainframes is available. Counters from the basic and problem-state counter set are mapped to generic perf hardware events. Other counters are accessible through raw events. For a list of available counter sets and counters, see: - The Load-Program-Parameter and the CPU-Measurement Facilities (SA23-2260) - The CPU-Measurement Facility Extended Counters Definition for z10 and z196 (SA23-2261) Reviewed-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Hendrik Brueckner <brueckner@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
