KVM: x86/pmu: Use different raw event masks for AMD and Intel
stable inclusion from stable-v5.10.137 commit 2ba1feb14363fd311f2cc912b58e5bb0b2b73662 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I60PLB Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=2ba1feb14363fd311f2cc912b58e5bb0b2b73662 -------------------------------- [ Upstream commit 95b065bf ] The third nybble of AMD's event select overlaps with Intel's IN_TX and IN_TXCP bits. Therefore, we can't use AMD64_RAW_EVENT_MASK on Intel platforms that support TSX. Declare a raw_event_mask in the kvm_pmu structure, initialize it in the vendor-specific pmu_refresh() functions, and use that mask for PERF_TYPE_RAW configurations in reprogram_gp_counter().
