  KVM: x86/mmu: Fix per-cpu counter corruption on 32-bit builds (2021-08-05 03:33:56 -0400)

----------------------------------------------------------------
Mostly bugfixes; plus, support for XMM arguments to Hyper-V hypercalls
now obeys KVM_CAP_HYPERV_ENFORCE_CPUID.  Both the XMM arguments feature
and KVM_CAP_HYPERV_ENFORCE_CPUID are new in 5.14, and each did not know
of the other.
