Merge tag 'kvmarm-fixes-6.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm64 fixes for 6.9, part #1 - Ensure perf events programmed to count during guest execution are actually enabled before entering the guest in the nVHE configuration. - Restore out-of-range handler for stage-2 translation faults. - Several fixes to stage-2 TLB invalidations to avoid stale translations, possibly including partial walk caches. - Fix early handling of architectural VHE-only systems to ensure E2H is appropriately set. - Correct a format specifier warning in the arch_timer selftest. - Make the KVM banner message correctly handle all of the possible configurations.
