Linus, The following changes since commit 4c07e2ddab5b6b57dbcb09aedbda1f484d5940cc: Merge tag 'mfd-next-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd (2019-09-23 19:37:49 -0700) are available in the git repository at: https://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/for-linus for you to fetch changes up to fd3edd4a9066f28de99a16685a586d68a9f551f8: KVM: nVMX: cleanup and fix host 64-bit mode checks (2019-09-25 19:22:33 +0200) ---------------------------------------------------------------- x86 KVM changes: * The usual accuracy improvements for nested virtualization * The usual round of code cleanups from Sean * Added back optimizations that were prematurely removed in 5.2 (the bare minimum needed to fix the regression was in 5.3-rc8, here comes the rest) * Support for UMWAIT/UMONITOR/TPAUSE * Direct L2->L0 TLB flushing when L0 is Hyper-V and L1 is KVM * Tell Windows guests if SMT is disabled on the host * More accurate detection of vmexit cost * Revert a pvqspinlock pessimization ---------------------------------------------------------------- Jim Mattson (3): kvm: x86: Add Intel PMU MSRs to msrs_to_save[] kvm: x86: Add "significant index" flag to a
