Linus Torvalds 1ebdbeb03e ARM:
- Proper emulation of the OSLock feature of the debug architecture
 
 - Scalibility improvements for the MMU lock when dirty logging is on
 
 - New VMID allocator, which will eventually help with SVA in VMs
 
 - Better support for PMUs in heterogenous systems
 
 - PSCI 1.1 support, enabling support for SYSTEM_RESET2
 
 - Implement CONFIG_DEBUG_LIST at EL2
 
 - Make CONFIG_ARM64_ERRATUM_2077057 default y
 
 - Reduce the overhead of VM exit when no interrupt is pending
 
 - Remove traces of 32bit ARM host support from the documentation
 
 - Updated vgic selftests
 
 - Various cleanups, doc updates and spelling fixes
 
 RISC-V:
 
 - Prevent KVM_COMPAT from being selected
 
 - Optimize __kvm_riscv_switch_to() implementation
 
 - RISC-V SBI v0.3 support
 
 s390:
 
 - memop selftest
 
 - fix SCK locking
 
 - adapter interruptions virtualization for secure guests
 
 - add Claudio Imbrenda as maintainer
 
 - first step to do proper storage key checking
 
 x86:
 
 - Continue switching kvm_x86_ops to static_call(); introduce
   static_call_cond() and __static_call_ret0 when applicable.
 
 - Cleanup unused arguments in several functions
 
 - Synthesize AMD 0x80000021 leaf
 
 - Fixes and optimization for Hyper-V sparse-bank hypercalls
 
 - Implement Hyper-V's enlightened MSR bitmap for nested SVM
 
 - Remove MMU auditing
 
 - Eager splitting of page tables (new aka "TDP" MMU only) when dirty
   page tracking is enabled
 
 - Cleanup the implementation of the guest PGD cache
 
 - Preparation for the implementation of Intel IPI virtualization
 
 - Fix some segment descriptor checks in the emulator
 
 - Allow AMD AVIC support on systems with physical APIC ID above 255
 
 - Better API to disable virtualization quirks
 
 - Fixes and optimizations for the zapping of page tables:
 
   - Zap roots in two passes, avoiding RCU read-side critical sections
     that last too long for very large guests backed by 4 KiB SPTEs.
 
   - Zap invalid and defunct roots asynchronously via concurrency-managed
     work queue.
 
   - Allowing yielding when zapping TDP MMU roots in response to the root's
     last reference being put.
 
   - Batch more TLB flushes with an RCU trick.  Whoever frees the paging
     structure now holds RCU as a proxy for all vCPUs running in the guest,
     i.e. to prolongs the grace period on their behalf.  It then kicks the
     the vCPUs out of guest mode before doing rcu_read_unlock().
 
 Generic:
 
 - Introduce __vcalloc and use it for very large allocations that
   need memcg accounting
