Linus,

The following changes since commit b9846a698c9aff4eb2214a06ac83638ad098f33f:

  KVM: VMX: add MSR_IA32_TSX_CTRL into msrs_to_save (2023-05-21 04:05:51 -0400)

  Merge tag 'kvm-x86-fixes-6.4' of https://github.com/kvm-x86/linux into HEAD (2023-06-03 15:16:58 -0400)

----------------------------------------------------------------
ARM:

* Address some fallout of the locking rework, this time affecting
  the way the vgic is configured

* Fix an issue where the page table walker frees a subtree and
  then proceeds with walking what it has just freed...

* Check that a given PA donated to the guest is actually memory
  (only affecting pKVM)

* Correctly handle MTE CMOs by Set/Way

* Fix the reported address of a watchpoint forwarded to userspace

* Fix the freeing of the root of stage-2 page tables

* Stop creating spurious PMU events to perform detection of the
  default PMU and use the existing PMU list instead.

x86:

* Fix a memslot lookup bug in the NX recovery thread that could
   theoretically let userspace bypass the NX hugepage mitigation

* Fix a s/BLOCKING/PENDING bug in SVM's vNMI support

* Account exit stats for fastpath VM-Exits that never leave the super
  tight run-loop

* Fix an out-of-bounds bug in the optimized APIC map code, and add a
  regression test for the race.
