Merge tag 'kvmarm-fixes-6.15-1' of https://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

KVM/arm64: First batch of fixes for 6.15

 - Rework heuristics for resolving the fault IPA (HPFAR_EL2 v. re-walk
   stage-1 page tables) to align with the architecture. This avoids
   possibly taking an SEA at EL2 on the page table walk or using an
   architecturally UNKNOWN fault IPA.

 - Use acquire/release semantics in the KVM FF-A proxy to avoid reading
   a stale value for the FF-A version.

 - Fix KVM guest driver to match PV CPUID hypercall ABI.

 - Use Inner Shareable Normal Write-Back mappings at stage-1 in KVM
   selftests, which is the only memory type for which atomic
   instructions are architecturally guaranteed to work.
