Merge tag 'kvmarm-fixes-6.16-3' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

KVM/arm64 fixes for 6.16, take #3

- Fix another set of FP/SIMD/SVE bugs affecting NV, and plugging some
  missing synchronisation

- A small fix for the irqbypass hook fixes, tightening the check and
  ensuring that we only deal with MSI for both the old and the new
  route entry

- Rework the way the shadow LRs are addressed in a nesting
  configuration, plugging an embarrassing bug as well as simplifying
  the whole process

- Add yet another fix for the dreaded arch_timer_edge_cases selftest
