Merge tag 'kvmarm-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

KVM/arm64 updates for 6.12

* New features:

  - Add a Stage-2 page table dumper, reusing the main ptdump
    infrastructure, and allowing easier debugging of the our
    page-table infrastructure

  - Add FP8 support to the KVM/arm64 floating point handling.

  - Add NV support for the AT family of instructions, which mostly
    results in adding a page table walker that deals with most of the
    complexity of the architecture.

* Improvements, fixes and cleanups:

  - Add selftest checks for a bunch of timer emulation corner cases

  - Fix the multiple of cases where KVM/arm64 doesn't correctly handle
    the guest trying to use a GICv3 that isn't advertised

  - Remove REG_HIDDEN_USER from the sysreg infrastructure, making
    things little more simple

  - Prevent MTE tags being restored by userspace if we are actively
    logging writes, as that's a recipe for disaster

  - Correct the refcount on a page that is not considered for MTE tag
    copying (such as a device)

  - Relax the synchronisation when walking a page table to split block
    mappings, moving it at the end the walk, as there is no need to
    perform it on every store.

  - Fix boundary check when transfering memory using FFA

  - Fix pKVM TLB invalidation, only affecting currently out of tree
    code but worth addressing for peace of mind
