Currently in validate_group(), there is a static initializer
for fake_pmu.used_mask which is based on CPU_BITS_NONE but
the used_mask array size is based on CCI_PMU_MAX_HW_EVENTS.
CCI_PMU_MAX_HW_EVENTS is not based on NR_CPUS, so CPU_BITS_NONE
is not correct and will cause a build failure if NR_CPUS
is set high enough to make CPU_BITS_NONE larger than used_mask.

Arnd, Olof, are you happy to take this via arm-soc?

My (broken) patch went via Will's tree because of a perf dependency, but
other CCI patches have gone via you guys.

Yeah, arm-soc is the best place for this. You should resend to
arm@xxxxxxxxxx as a new patch with the relevant acks.
Mark

Could you please send this to arm-soc as suggested by Will, with the relevant acks/reviews ?

Thanks
Suzuki
