  KVM: SVM: Update x2APIC MSR intercepts if AVIC is inhibited while L2 is active (2026-07-29 23:39:36 +0200)

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

- Fix a tiny buglet when propagating the deactivation of an interrupt
  from a nested guest, which happened to trigger a gold plated CPU bug
  on a particular implementation

- Fix a race between LPI unmapping and mapping, resulting in leaked
  LPIs

- Make LPI mapping more robust on memory allocation failure

- Fix the handling of the EL2 tracing clock being disabled

- A couple of Sashiko-driven fixes for corner cases in the EL2 tracing
  code

- Add missing sysreg tracepoint for the EL2 code

- Tidy-up the mutual exclusion of guest-memfd and MTE

- Update Fuad's email address to point to @linux.dev

s390:

- several fixes for PCI passthru in s390 kvm

- fix a 7.2-rc regression in the adapter interrupt mapping code

x86:

- Add memory clobber to asm for VMX instructions; without one, the compiler
  could reorder them in troublesome ways because "asm volatile" and "asm goto"
  only protect against removal of the asm.

- Cancel delayed I/O APIC EOI handling before destroying vCPUs

- Check all address spaces (normal and SMM) for write tracking and large
  pages, not just the current one.

- Always update x2APIC MSR intercepts for L1 when AVIC is deactivated,
  even if not running L1.  If the deactivation is VM-wide rather than being
  caused by something in L2's vCPU state, after a nested vmexit L1 will
  be able to access the host's APIC state.
