[GIT PULL] KVM/arm64 fixes for 7.2, take #1

[GIT PULL] KVM/arm64 fixes for 7.2, take #1

[Marc Zyngier]

Paolo,

As predicted, here's another largeish set of fixes for KVM/arm64. A
bunch of them are fairly benign (the PSTATE.IL stuff), but some are
pretty annoying (vgic, MOPS) and are stable material.

On the bright side, Fuad has volunteered to be an official reviewer.
We really need people to engage with the reviewing process instead of
simply dumping patches on us, as me and Oliver really can't be
stretched much further. So many thanks Fuad for offering to help.

I expect to be back next week with a similar delivery, as my Inbox
keeps filling with this stuff...

Please pull,

	M.

  KVM: arm64: account pKVM reclaim against the VM mm (2026-06-22 10:48:08 +0100)

----------------------------------------------------------------
KVM/arm64 fixes for 7.2, take #1

- Fix an accounting buglet when reclaiming pages from a protected
  guest

- Fix a bunch of architectural compliance issues when injecting a
  synthesised exception, most of which were missing the PSTATE.IL bit
  indicating a 32bit-wide instruction

- Another set of fixes addressing issues with translation of VNCR_EL2,
  including corner cases where the guest point that register at a RO
  page...

- Don't warn when trapping accesses to ZCR_EL2 from an L2 guest, as
  that's not unexpected at all

- Address a bunch of races with LPI migration vs LPIs being disabled

- Fix a total howler of a bug combining FEAT_MOPS and NV, resulting in
  exception returning in the wrong place...

- Coerce Fuad Tabba into a reviewer role, and may his Inbox catch
  fire!
