Linus Torvalds 152d32aa84 ARM:
- Stage-2 isolation for the host kernel when running in protected mode
 
 - Guest SVE support when running in nVHE mode
 
 - Force W^X hypervisor mappings in nVHE mode
 
 - ITS save/restore for guests using direct injection with GICv4.1
 
 - nVHE panics now produce readable backtraces
 
 - Guest support for PTP using the ptp_kvm driver
 
 - Performance improvements in the S2 fault handler
 
 x86:
 
 - Optimizations and cleanup of nested SVM code
 
 - AMD: Support for virtual SPEC_CTRL
 
 - Optimizations of the new MMU code: fast invalidation,
   zap under read lock, enable/disably dirty page logging under
   read lock
 
 - /dev/kvm API for AMD SEV live migration (guest API coming soon)
 
 - support SEV virtual machines sharing the same encryption context
 
 - support SGX in virtual machines
 
 - add a few more statistics
 
 - improved directed yield heuristics
 
 - Lots and lots of cleanups
 
 Generic:
 
 - Rework of MMU notifier interface, simplifying and optimizing
 the architecture-specific code
 
 - Some selftests improvements

Pull kvm updates from Paolo Bonzini:
 "This is a large update by KVM standards, including AMD PSP (Platform
  Security Processor, aka "AMD Secure Technology") and ARM CoreSight
  (debug and trace) changes.

  ARM:

   - CoreSight: Add support for ETE and TRBE

   - Stage-2 isolation for the host kernel when running in protected
     mode

   - Guest SVE support when running in nVHE mode

   - Force W^X hypervisor mappings in nVHE mode

   - ITS save/restore for guests using direct injection with GICv4.1

   - nVHE panics now produce readable backtraces

   - Guest support for PTP using the ptp_kvm driver

   - Performance improvements in the S2 fault handler

  x86:

   - AMD PSP driver changes

   - Optimizations and cleanup of nested SVM code

   - AMD: Support for virtual SPEC_CTRL

   - Optimizations of the new MMU code: fast invalidation, zap under
