Linus,

The following changes since commit 8ffd015db85fea3e15a77027fda6c02ced4d2444:

  Linux 6.15-rc2 (2025-04-13 11:54:49 -0700)

  Merge tag 'kvmarm-fixes-6.15-2' of https://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD (2025-04-24 13:28:53 -0400)

Compared to last week's botched attempt, this includes your suggestion
to make kvm_arch_has_irq_bypass() inline and a new ARM fix.

Paolo

----------------------------------------------------------------
ARM:

* Single fix for broken usage of 'multi-MIDR' infrastructure in PI
  code, adding an open-coded erratum check for everyone's favorite pile
  of sand: Cavium ThunderX

x86:

* Bugfixes from a planned posted interrupt rework

* Do not use kvm_rip_read() unconditionally to cater for guests
  with inaccessible register state.
