Merge branch 'kvm-v6.2-rc4-fixes' into HEAD
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
