    Linus Torvalds authored
    Pull KVM updates from Radim Krčmář:
       - Improved guest IPA space support (32 to 52 bits)
       - RAS event delivery for 32bit
       - PMU fixes
       - Guest entry hardening
       - Various cleanups
       - Port of dirty_log_test selftest
       - Nested HV KVM support for radix guests on POWER9. The performance
         is much better than with PR KVM. Migration and arbitrary level of
         nesting is supported.
       - Disable nested HV-KVM on early POWER9 chips that need a particular
         hardware bug workaround
       - One VM per core mode to prevent potential data leaks
       - PCI pass-through optimization
       - merge ppc-kvm topic branch and kvm-ppc-fixes to get a better base
       - Initial version of AP crypto virtualization via vfio-mdev
       - Improvement for vfio-ap
       - Set the host program identifier
       - Optimize page table locking
       - Enable nested virtualization by default
       - Implement Hyper-V IPI hypercalls
       - Improve #PF and #DB handling
       - Allow guests to use Enlightened VMCS
       - Add migration selftests for VMCS and Enlightened VMCS
       - Allow coalesced PIO accesses
       - Add an option to perform nested VMCS host state consistency check
         through hardware
       - Automatic tuning of lapic_timer_advance_ns
       - Many fixes, minor improvements, and cleanups"
