  KVM: x86/xen: Avoid deadlock by adding kvm->arch.xen.xen_lock leaf node lock (2023-01-11 17:45:58 -0500)

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

* Fix the PMCR_EL0 reset value after the PMU rework

* Correctly handle S2 fault triggered by a S1 page table walk
  by not always classifying it as a write, as this breaks on
  R/O memslots

* Document why we cannot exit with KVM_EXIT_MMIO when taking
  a write fault from a S1 PTW on a R/O memslot

* Put the Apple M2 on the naughty list for not being able to
  correctly implement the vgic SEIS feature, just like the M1
  before it

* Reviewer updates: Alex is stepping down, replaced by Zenghui

x86:

* Fix various rare locking issues in Xen emulation and teach lockdep
  to detect them

* Documentation improvements

* Do not return host topology information from KVM_GET_SUPPORTED_CPUID
