[GIT PULL] KVM/arm64 fixes for 7.2, take #3

[Marc Zyngier]

Paolo,

Here's another set of KVM/arm64 fixes for 7.2. A bunch of fixes for
AI-discovered issues, with two main areas of activity:

- plugging annoying LPI mapping races

- fixing corner cases in the EL2 tracing management

The rest is a heady mix of CPU errata workaround, API tidy up and low
impact fixes.

Please pull,

	M.

  KVM: arm64: Reject guest_memfd memslots when the VM has MTE (2026-07-23 09:57:06 +0100)

----------------------------------------------------------------
KVM/arm64 fixes for 7.2, take #3

- 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
