[GIT PULL] KVM: x86: Fixes for 7.2-rcN

[Sean Christopherson]

Please pull x86 fixes for 7.2.  Nothing in here is super urgent, but all of
these are fixes for high-impact bugs (though the ept=n bugs are agruably not
impactful in practice).

Note, the tag is based on v7.2-rc2.

The following changes since commit 8cdeaa50eae8dad34885515f62559ee83e7e8dda:

  Linux 7.2-rc2 (2026-07-05 14:44:06 -1000)

  KVM: x86: Fix null pointer deref due to dummy array in trace_kvm_inj_exception() (2026-07-13 06:24:36 -0700)

----------------------------------------------------------------
KVM x86 fixes for 7.2-rcN

 - Fix a bug where KVM will trigger a UAF if updating IOMMU IRTEs fails when
   registering an IRQ-bypass producer.

 - Ignore pending PV EOI instead of BUG()ing the host if the feature was
   disabled by the guest.

 - Fix nVMX bugs where KVM would run L1 with an L1-controlled CR3 after a
   failed "late" consistency check when KVM is NOT using EPT.

 - Disallow intra-host migration/mirroring of SNP VMs as KVM doesn't yet
   support moving/mirroring SNP state.

 - Fix a TOCTOU bug in KVM's handling of the "trusted" CPUID for TDX guests.

 - Fix a NULL pointer deref in trace_kvm_inj_exception() where a change to the
   core infrastructure missed KVM's unique (ab)use of __print_symbolic().

... but the similar PDPTR issue might be, I'll figure out that one out.

Pulled, thanks.
