[GIT PULL] KVM/arm64 fixes for 7.0, take #3

[Marc Zyngier <maz@kernel.org>]

Paolo,

Here's the third set of fixes for 7.0. Two fixes, both related to the
pretty large vgic rewrite that went into 6.19. One is affecting
interrupt deactivation, and therefore leading to guests locking
up. The other is affecting CPU hotplug with pKVM, leading to the
onlined CPU not booting at all.

Please pull,

	M.

  KVM: arm64: pkvm: Don't reprobe for ICH_VTR_EL2.TDS on CPU hotplug (2026-03-10 09:48:45 +0000)

----------------------------------------------------------------
KVM/arm64 fixes for 7.0, take #3

- Correctly handle deeactivation of out-of-LRs interrupts by
  starting the EOIcount deactivation walk *after* the last irq
  that made it into an LR. This avoids deactivating irqs that
  are in the LRs and that the vcpu hasn't deactivated yet.

- Avoid calling into the stubs to probe for ICH_VTR_EL2.TDS when
  pKVM is already enabled -- not only thhis isn't possible (pKVM
  will reject the call), but it is also useless: this can only
  happen for a CPU that has already booted once, and the capability
  will not change.
