[GIT,PULL] arm64 updates for 6.8

  Hi Linus,

Please pull these New Year arm64 updates for 6.8. As per usual, there is
a summary in the tag, but here are a few minor things to be aware of:

  - There's a trivial conflict with the arm-soc tree in linux-next [1],
    since we're both touching the 32-bit Arm PMU code. The arm-soc tree
    removes support for the infamous 11MPcore CPU entirely (good
    riddance), so the change here in 5cd7da19cb97 ("arm: perf: Remove
    PMU locking") to remove unnecessary locking from
    armv6mpcore_pmu_disable_event() is touching code that is removed
    completely.

  - The for-next/lpa2-prep and for-next/sysregs branches are shared with
    kvmarm, as they build on top to enable 52-bit addressing (IPAs) and
    fine-grained traps for guests.

  - We've got a new PMU driver for the Synopsys DesignWare PCIe IP;
    Bjorn has Acked the PCI changes.

  - I've ended up merging our 6.7 fixes branch (for-next/fixes) so we
    could update some CPU capability-checking logic in the KPTI enabling
    code. Consequently, the diffstat is a tiny bit wonky due to the
    three fixes that were merged after -rc3. I don't particularly like
    changing that by hand, so you've got the raw thing (against -rc3)
    here.

Should all be straightforward, but please shout if not.

Cheers,

Will

  Merge branch 'for-next/fixes' into for-next/core (2024-01-04 12:32:33 +0000)

----------------------------------------------------------------
arm64 updates for 6.8

* for-next/cpufeature

  - Remove ARM64_HAS_NO_HW_PREFETCH copy_page() optimisation for ye olde
    Thunder-X machines.
  - Avoid mapping KPTI trampoline when it is not required.
  - Make CPU capability API more robust during early initialisation.

* for-next/early-idreg-overrides

  - Remove dependencies on core kernel helpers from the early
    command-line parsing logic in preparation for moving this code
    before the kernel is mapped.

* for-next/fpsimd

  - Restore kernel-mode fpsimd context lazily, allowing us to run fpsimd
    code sequences in the kernel with pre-emption enabled.

* for-next/kbuild

  - Install 'vmlinuz.efi' when CONFIG_EFI_ZBOOT=y.
  - Makefile cleanups.

* for-next/lpa2-prep

  - Preparatory work for enabling the 'LPA2' extension, which will
    introduce 52-bit virtual and physical addressing even with 4KiB
    pages (including for KVM guests).

* for-next/misc

  - Remove dead code and fix a typo.

* for-next/mm

  - Pass NUMA node information for IRQ stack allocations.

* for-next/perf

  - Add perf support for the Synopsys DesignWare PCIe PMU.
  - Add support for event counting thresholds (FEAT_PMUv3_TH) introduced
    in Armv8.8.
  - Add support for i.MX8DXL SoCs to the IMX DDR PMU driver.
  - Minor PMU driver fixes and optimisations.

* for-next/rip-vpipt

  - Remove what support we had for the obsolete VPIPT I-cache policy.

* for-next/selftests

  - Improvements to the SVE and SME selftests.

* for-next/stacktrace

  - Refactor kernel unwind logic so that it can used by BPF unwinding
    and, eventually, reliable backtracing.

* for-next/sysregs

  - Update a bunch of register definitions based on the latest XML drop
    from Arm.
