  KVM: SVM: Bump asid_generation on CPU online to avoid ASID collision after hotplug (2026-07-16 08:55:03 +0200)

A larger pull request with everything that accumulated while I was
away from git.

----------------------------------------------------------------
Arm:

- 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...

- Move locking for kvm_io_bus_get_dev() into the caller, ensuring
  race-free checks that the returned object is of the correct type

- Fix initialisation of the page-table walk level when relaxing
  permissions

- Correctly update the XN attribute when relaxing permissions

- Fix the sign extension of loads from emulated MMIO regions

- Assorted collection of fixes for pKVM's FFA proxy, together with a
  couple of FFA driver adjustments

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

s390:

- more gmap KVM memory management fixes

- PCI passthru fixes

x86:

- 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().

- Put vmcs12 pages if nested VM-Enter fails due to invalid guest state

- Fix TLB conflicts between two VMs if one of them VM is run on a CPU before
  and after it is hotplugged.
