[GIT PULL] KVM/arm64 fixes, take #3

[Marc Zyngier]

Paolo,

Here's the third set of KVM/arm64 fixes for 6.16. The most notable
thing is yet another batch of FP/SVE fixes from Mark, this time
addressing NV, and additionally plugging some missing synchronisation.
The rest is a mix of interrupt stuff (routing change, mishandling of
shadow LRs) and selftest fixes.

Please pull,

	M.

  KVM: arm64: VHE: Centralize ISBs when returning to host (2025-06-19 13:34:59 +0100)

----------------------------------------------------------------
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
