Linus Torvalds 36824f198c ARM:
- Add MTE support in guests, complete with tag save/restore interface
 
 - Reduce the impact of CMOs by moving them in the page-table code
 
 - Allow device block mappings at stage-2
 
 - Reduce the footprint of the vmemmap in protected mode
 
 - Support the vGIC on dumb systems such as the Apple M1
 
 - Add selftest infrastructure to support multiple configuration
   and apply that to PMU/non-PMU setups
 
 - Add selftests for the debug architecture
 
 - The usual crop of PMU fixes
 
 PPC:
 
 - Support for the H_RPT_INVALIDATE hypercall
 
 - Conversion of Book3S entry/exit to C
 
 - Bug fixes
 
 S390:
 
 - new HW facilities for guests
 
 - make inline assembly more robust with KASAN and co
 
 x86:
 
 - Allow userspace to handle emulation errors (unknown instructions)
 
 - Lazy allocation of the rmap (host physical -> guest physical address)
 
 - Support for virtualizing TSC scaling on VMX machines
 
 - Optimizations to avoid shattering huge pages at the beginning of live migration
 
 - Support for initializing the PDPTRs without loading them from memory
 
 - Many TLB flushing cleanups
 
 - Refuse to load if two-stage paging is available but NX is not (this has
   been a requirement in practice for over a year)
 
 - A large series that separates the MMU mode (WP/SMAP/SMEP etc.) from
   CR0/CR4/EFER, using the MMU mode everywhere once it is computed
   from the CPU registers
 
 - Use PM notifier to notify the guest about host suspend or hibernate
 
 - Support for passing arguments to Hyper-V hypercalls using XMM registers
 
 - Support for Hyper-V TLB flush hypercalls and enlightened MSR bitmap on
   AMD processors
 
 - Hide Hyper-V hypercalls that are not included in the guest CPUID
 
 - Fixes for live migration of virtual machines that use the Hyper-V
   "enlightened VMCS" optimization of nested virtualization
 
 - Bugfixes (not many)
 
 Generic:
 
 - Support for retrieving statistics without debugfs
