[GIT PULL] KVM/arm64 fix for 6.18, take #3

[GIT PULL] KVM/arm64 fix for 6.18, take #3

[Marc Zyngier]

Paolo,

I'm back with my weekly routine of collecting patches, plugging
another couple of regressions (the FGT one is particularly annoying).
I hope this is the last one for this cycle, but my gut feeling is that
we're not quite finished with it yet...

Please pull,

	M.

The following changes since commit 4af235bf645516481a82227d82d1352b9788903a:

  KVM: arm64: VHE: Compute fgt traps before activating them (2025-11-12 10:52:58 +0000)

----------------------------------------------------------------
KVM/arm64 fixes for 6.18, take #3

- Only adjust the ID registers when no irqchip has been created once
  per VM run, instead of doing it once per vcpu, as this otherwise
  triggers a pretty bad conbsistency check failure in the sysreg code.

- Make sure the per-vcpu Fine Grain Traps are computed before we load
  the system registers on the HW, as we otherwise start running without
  anything set until the first preemption of the vcpu.
