    Subject[PATCH v12 01/16] perf/x86/intel: Fix the comment about guest LBR support on KVM
    Date
    From: Like Xu <like.xu@linux.intel.com>

    Starting from v5.12, KVM reports guest LBR and extra_regs support
    when the host has relevant support. Just delete this part of the
    comment and fix a typo incidentally.
