Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull kvm updates from Paolo Bonzini:
"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"

However, as we are about to support additional hypercalls, factor out
this functionality into a separate hypercall handler file.
