Subject: [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.
