Please pull/merge a pile of x86 cleanups and fixes, most of which have been waiting for review/merge for quite some time. The only non-trivial changes that haven't been posted are the massaged version of the PMU cleanup patches. Note, the very last commit will fail spectacularly on kvm/queue due to a KVM bug: https://lore.kernel.org/all/20220607213604.3346000-4-seanjc@xxxxxxxxxx. Other than that, tested on Intel and AMD, both 64-bit and 32-bit. Thanks!
