Thank you!
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 [1] https://lore.kernel.org/r/20240103100324.05f47bb8@canb.auug.org.au --->8 The following changes since commit 2cc14f52aeb78ce3f29677c2de1f06c0e91471ab: Linux 6.7-rc3 (2023-11-26 19:59:33 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git tags/arm64-upstream for you to fetch changes up to db32cf8e280b46726065c518e90761bb0229bacf: 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. ---------------------------------------------------------------- Anshuman Khandual (4): arm64/mm: Add FEAT_LPA2 specific ID_AA64MMFR0.TGRAN[2] drivers: perf: arm_pmuv3: Add
