Revert "ARM: mach-virt: Select PMUv3 driver by default"
This reverts commit 3b16f6268e660f15aed0bb97aefe87e893eb8882. Selecting a Kconfig option that has its own set of dependencies tends to end badly, and in this case 'randconfig' builds blew up on 32-bit ARM where ARM_PMUV3 was being selecting with HW_PERF_EVENTS=n: | drivers/perf/arm_pmuv3.c:68:5: error: use of undeclared identifier 'DTLB' | [C(DTLB)][C(OP_READ)][C(RESULT_ACCESS)] = ARMV8_PMUV3_PERFCTR_L1D_TLB, | ^ | fatal error: too many errors emitted, stopping now [-ferror-limit=] | 20 errors generated. | | Kconfig warnings: (for reference only) | WARNING: unmet direct dependencies detected for ARM_PMUV3 | Depends on [n]: PERF_EVENTS [=y] && HW_PERF_EVENTS [=n] && (ARM [=y] && CPU_V7 [=y] || ARM64) | Selected by [y]: | - ARCH_VIRT [=y] && ARCH_MULTI_V7 [=y] && PERF_EVENTS [=y] As suggested by Marc, just drop the 'select' clause altogether by reverting the patch which introduced it.
