[Paolo Bonzini]

Linus,

The following changes since commit ef057cbf825e03b63f6edf5980f96abf3c53089d:

  KVM: x86/mmu: Ensure hugepage is in by slot before checking max mapping level (2026-06-16 00:39:57 +0200)

  x86/apic: KVM: Use cpu_physical_id() to get APIC ID of running vCPU for AVIC (2026-06-24 07:52:24 -0400)

----------------------------------------------------------------
s390:

* Fix S390_USER_OPEREXEC so it can now be enabled regardless of other
  unrelated capabilities

* Fix handling of the _PAGE_UNUSED pte bit that could lead to guest
  memory corruption in some scenarios

* A bunch of misc gmap fixes (locking, behaviour under memory pressure)

* Fix CMMA dirty tracking

x86:

* Tidy up some WARN_ON() and BUG_ON(), replacing them with WARN_ON_ONCE()
  or KVM_BUG_ON().  All of these have obviously never triggered, or
  somebody would have been annoyed earlier, but still.

* Fix missing interrupt due to stale CR8 intercept

* Add a statistic that can come in handy to debug leaks as well as the
  vulnerability to a class of recently-discovered issues.

* Do not ask arch/x86/kernel to export default_cpu_present_to_apicid()
  just for KVM.
