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

Pull kvm updates from Paolo Bonzini:
"RISCV:

- Use common KVM implementation of MMU memory caches

- SBI v0.2 support for Guest

- Initial KVM selftests support

- Fix to avoid spurious virtual interrupts after clearing hideleg CSR

- Update email address for Anup and Atish

ARM:

- Simplification of the 'vcpu first run' by integrating it into KVM's
'pid change' flow

- Refactoring of the FP and SVE state tracking, also leading to a
simpler state and less shared data between EL1 and EL2 in the nVHE
case

- Tidy up the header file usage for the nvhe hyp object

- New HYP unsharing mechanism, finally allowing pages to be unmapped
from the Stage-1 EL2 page-tables

- Various pKVM cleanups around refcounting and sharing

- A couple of vgic fixes for bugs that would trigger once the vcpu
xarray rework is merged, but not sooner

- Add minimal support for ARMv8.7's PMU extension

- Rework kvm_pgtable initialisation ahead of the NV work

- New selftest for IRQ injection

- Teach selftests about the lack of default IPA space and page sizes

- Expand sysreg selftest to deal with Pointer Authentication

- The usual bunch of cleanups and doc update

s390:

- fix sigp sense/start/stop/inconsistency

- cleanups

x86:

- Clean up some function prototypes more

- improved gfn_to_pfn_cache with proper invalidation, used by Xen
emulation

- add KVM_IRQ_ROUTING_XEN_EVTCHN and event channel delivery

- completely remove potential TOC/TOU races in nested SVM consistency
checks

- update some PMCs on emulated instructions

- Intel AMX support (joint work between Thomas and Intel)

- large MMU cleanups

- module parameter to disable PMU virtualization

- cleanup register cache

- first part of halt handling cleanups

- Hyper-V enlightened MSR bitmap support for nested hypervisors

Generic:

- clean up Makefiles

- introduce CONFIG_HAVE_KVM_DIRTY_RING

- optimize memslot lookup using a tree

- optimize vCPU array usage by converting to xarray"
