There's the usual summary in the tag, with the highlights this time being support for dynamically enabling/disabling Clang's Shadow Call Stack at boot and a long-awaited optimisation to the way in which we handle the SVE register state on system call entry to avoid taking unnecessary traps from userspace. A few small things to note: * for-next/sysregs is shared with the KVM tree, since it conflicts with some rework of the PMU handling code in the hypervisor. * We have some refactoring changes to the core ftrace code reworking FTRACE_WITH_REGS and fixing up PowerPC, S390 and x86 (acked by Steve and Masami). We build on top of this to enable FTRACE_WITH_ARGS on arm64. * We dropped for-next/uaccess fairly late in the cycle after Syzkaller ran into an issue with the fault handling in copy_to_user(). Hopefully we'll bring it back next time once we've got deterministic testing coverage of all the exception fixups. It's all been sitting happily in -next for a while now. Cheers, Will --->8 The following changes since commit f0c4d9fc9cc9462659728d168387191387e903cc: Linux 6.1-rc4 (2022-11-06 15:07:11 -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 5f4c374760b031f06c69c2fdad1b0e981a1ad42f: Merge branch 'for-next/undef-traps' into for-next/core (2022-12-06 11:34:25 +0000) ---------------------------------------------------------------- arm64 updates for 6.2 ACPI: * Enable FPDT support for boot-time profiling * Fix CPU PMU probing to work better with PREEMPT_RT * Update SMMUv3 MSI DeviceID parsing to latest IORT spec * APMT support for probing Arm CoreSight PMU devices CPU features: * Advertise new SVE instructions (v2.1) * Advertise range prefetch instruction * Advertise CSSC ("Common Short Sequence Compression") scalar instructions, adding things like min, max, abs, popcount * Enable DIT (Data Independent Timing) when running in the kernel * More conversion of system register fields over to the generated header CPU misfeatures: * Workaround for Cortex-A715 erratum #2645198 Dynamic SCS: * Support for dynamic shadow call stacks to allow switching at runtime between Clang's SCS implementation and the CPU's pointer authentication feature when it is supported (complete with scary DWARF parser!) Tracing and debug: * Remove static ftrace in favour of, err, dynamic ftrace! * Seperate 'struct ftrace_regs' from 'struct pt_regs' in core ftrace and existing arch code * Introduce and implement FTRACE_WITH_ARGS on arm64 to replace the old FTRACE_WITH_REGS * Extend 'crashkernel=' parameter with default value and fallback to placement above 4G physical if initial (low) allocation fails SVE: * Optimisation to avoid disabling SVE unconditionally on syscall entry and just zeroing the non-shared state on return instead Exceptions: * Rework of undefined instruction handling to avoid serialisation on global lock (this includes emulation of user accesses to the ID registers) Perf and PMU: * Support for TLP filters in Hisilicon's PCIe PMU device * Support for the DDR PMU present in Amlogic Meson G12 SoCs * Support for the terribly-named "CoreSight PMU" architecture from Arm (and Nvidia's implementation of said architecture) Misc: * Tighten up our boot protocol for systems with memory above 52 bits physical * Const-ify static keys to satisty jump label asm constraints * Trivial FFA driver cleanups in preparation for v1.1 support * Export the kernel_neon_* APIs as GPL symbols * Harden our instruction generation routines against instrumentation * A bunch of robustness improvements to our arch-specific selftests * Minor cleanups and fixes all over (kbuild, kprobes, kfence, PMU, ...) ---------------------------------------------------------------- Anshuman Khandual (9): arm64/mm: Drop ARM64_KERNEL_USES_PMD_MAPS arm64/mm: Simplify and document pte_to_phys() for 52 bit
