arm64: KVM: fix build with CONFIG_ARM_PMU disabled
When CONFIG_ARM_PMU is disabled, we get the following build error: arch/arm64/kvm/sys_regs.c: In function 'pmu_counter_idx_valid': arch/arm64/kvm/sys_regs.c:564:27: error: 'ARMV8_PMU_CYCLE_IDX' undeclared (first use in this function) if (idx >= val && idx != ARMV8_PMU_CYCLE_IDX) ^ arch/arm64/kvm/sys_regs.c:564:27: note: each undeclared identifier is reported only once for each function it appears in arch/arm64/kvm/sys_regs.c: In function 'access_pmu_evcntr': arch/arm64/kvm/sys_regs.c:592:10: error: 'ARMV8_PMU_CYCLE_IDX' undeclared (first use in this function) idx = ARMV8_PMU_CYCLE_IDX; ^ arch/arm64/kvm/sys_regs.c: In function 'access_pmu_evtyper': arch/arm64/kvm/sys_regs.c:638:14: error: 'ARMV8_PMU_CYCLE_IDX' undeclared (first use in this function) if (idx == ARMV8_PMU_CYCLE_IDX) ^ arch/arm64/kvm/hyp/switch.c:86:15: error: 'ARMV8_PMU_USERENR_MASK' undeclared (first use in this function) write_sysreg(ARMV8_PMU_USERENR_MASK, pmuserenr_el0); This patch fixes the build with CONFIG_ARM_PMU disabled.
