Paolo,
Here the second batch of fixes for 6.16. We have a significant rework
of our system register accessors so that the RES0/RES1 sanitisation
gets applied at the right time, and a bunch of fixes for a single
selftest that really *never* worked.
Please pull,
M.

KVM: arm64: selftests: Determine effective counter width in arch_timer_edge_cases (2025-06-05 14:28:44 +0100)
----------------------------------------------------------------
KVM/arm64 fixes for 6.16, take #2
- Rework of system register accessors for system registers that are
directly writen to memory, so that sanitisation of the in-memory
value happens at the correct time (after the read, or before the
write). For convenience, RMW-style accessors are also provided.
- Multiple fixes for the so-called "arch-timer-edge-cases' selftest,
which was always broken.
