From: Mark Salter <msalter@xxxxxxxxxx> 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. This patch changes the used_mask initialization to be runtime based on the actual size of the array.
