Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon: "The highlights this time are support for dynamically enabling and 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. Summary: 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, ...)" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (151 commits) arm64: kprobes: Return DBG_HOOK_ERROR if kprobes can not handle a BRK arm64: kprobes: Let arch do_page_fault() fix up page fault in user handler arm64: Prohibit instrumentation on arch_stack_walk() arm64:uprobe fix the uprobe SWBP_INSN in big-endian arm64: alternatives: add __init/__initconst to some functions/variables arm_pmu: Drop redundant armpmu->map_event() in armpmu_event_init() kselftest/arm64: Allow epoll_wait() to return more than one result kselftest/arm64: Don't drain output while spawning children kselftest/arm64: Hold fp-stress children until they're all spawned arm64/sysreg: Remove duplicate definitions from asm/sysreg.h arm64/sysreg: Convert ID_DFR1_EL1 to automatic generation arm64/sysreg: Convert ID_DFR0_EL1 to automatic generation arm64/sysreg: Convert ID_AFR0_EL1 to automatic generation arm64/sysreg: Convert ID_MMFR5_EL1 to automatic generation arm64/sysreg: Convert MVFR2_EL1 to automatic generation arm64/sysreg: Convert MVFR1_EL1 to automatic generation arm64/sysreg: Convert MVFR0_EL1 to automatic generation arm64/sysreg: Convert ID_PFR2_EL1 to automatic generation arm64/sysreg: Convert ID_PFR1_EL1 to automatic generation arm64/sysreg: Convert ID_PFR0_EL1 to automatic generation ...
