Subject: [GIT PULL] KVM/arm64 fixes for 7.0, take #2
Date: Fri,  6 Mar 2026 11:22:31 +0000	[thread overview]
Message-ID: <20260306112231.3201502-1-maz@kernel.org> (raw)

Paolo,

Here's the second set of fixes for 7.0. The only interesting fix is
one affecting pKVM and preventing the host from making forward
progress when a memblock is not page-aligned.

The rest is a bunch of low-severity fixes affecting the page-table
code, some of which Fuad has promised to start cleaning up!

Please pull,

	M.

The following changes since commit 11439c4635edd669ae435eec308f4ab8a0804808:

  KVM: arm64: Remove the redundant ISB in __kvm_at_s1e2() (2026-03-06 10:42:21 +0000)

----------------------------------------------------------------
KVM/arm64 fixes for 7.0, take #2

- Fix a couple of low-severity bugs in our S2 fault handling path,
  affecting the recently introduced LS64 handling and the even more
  esoteric handling of hwpoison in a nested context

- Address yet another syzkaller finding in the vgic initialisation,
  were we would end-up destroying an uninitialised vgic, with nasty
  consequences

- Address an annoying case of pKVM failing to boot when some of the
  memblock regions that the host is faulting in are not page-aligned

- Inject some sanity in the NV stage-2 walker by checking the limits
  against the advertised PA size, and correctly report the resulting
  faults

- Drop an unnecessary ISB when emulating an EL2 S1 address translation

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