Hi Paolo,
Happy new year!
Here's the first batch of fixes for KVM/arm64 for 6.2. We have two
important fixes this time around, one for the PMU emulation, and the
other for guest page table walks in read-only memslots, something that
EFI has started doing...
The rest is mostly documentation updates, cleanups, and an update to
the list of reviewers (Alexandru stepping down, and Zenghui joining
the fun).
Please pull,
M.

----------------------------------------------------------------
KVM/arm64 fixes for 6.2, take #1
- 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 step for not being able to
correctly implement the vgic SEIS feature, just liek the M1
before it
- Reviewer updates: Alex is stepping down, replaced by Zenghui
