[GIT,PULL] arm64 updates for 5.3

Hi Linus, I'm sending an early pull request for 5.3 as I'll be on holiday for the next two weeks. The PTRACE_SYSEMU patches touch powerpc and x86 lightly (the acks are in place). There are a few conflicts but nothing complicated, the resolution is as per linux-next. If anything goes wrong, Will is around during the merging window. Thanks. The following changes since commit f2c7c76c5d0a443053e94adb9f0918fa2fb85c3a: Linux 5.2-rc3 (2019-06-02 13:55:33 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux tags/arm64-upstream for you to fetch changes up to 0c61efd322b75ed3143e3d130ebecbebf561adf5: Merge branch 'for-next/perf' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux (2019-07-01 15:53:35 +0100) ---------------------------------------------------------------- arm64 updates for 5.3: - arm64 support for syscall emulation via PTRACE_SYSEMU{,_SINGLESTEP} - Wire up VM_FLUSH_RESET_PERMS for arm64, allowing the core code to manage the permissions of executable vmalloc regions more strictly - Slight performance improvement by keeping softirqs enabled while touching the FPSIMD/SVE state (kernel_neon_begin/end) - Expose a couple of ARMv8.5 features to user (HWCAP): CondM (new XAFLAG and AXFLAG instructions for floating point comparison flags manipulation) and FRINT (rounding floating point numbers to integers) - Re-instate ARM64_PSEUDO_NMI support which was previously marked as BROKEN due to some bugs (now fixed) - Improve parking of stopped CPUs and implement an arm64-specific panic_smp_self_stop() to avoid warning on not being able to stop secondary CPUs during panic - perf: enable the ARM Statistical Profiling Extensions (SPE) on ACPI platforms - perf: DDR performance monitor support for iMX8QXP - cache_line_size() can now be set from DT or ACPI/PPTT if provided to cope with a system cache info not exposed via the CPUID registers - Avoid warning on hardware cache line size greater than ARCH_DMA_MINALIGN if the system is fully coherent - arm64 do_page_fault() and hugetlb cleanups - Refactor set_pte_at() to avoid redundant READ_ONCE(*ptep) - Ignore ACPI 5.1 FADTs reported as 5.0 (infer from the 'arm_boot_flags' introduced in 5.1) - CONFIG_RANDOMIZE_BASE now enabled in defconfig - Allow the selection of ARM64_MODULE_PLTS, currently only done via RANDOMIZE_BASE (and an erratum workaround), allowing modules to spill over into the vmalloc area - Make ZONE_DMA32 configurable ---------------------------------------------------------------- Aaro Koskinen (1): arm64: Implement panic_smp_self_stop() Anshuman Khandual (10): arm64/hugetlb: Use macros for contiguous huge page sizes arm64/mm: Move PTE_VALID from SW defined to HW page table entry definitions arm64/mm: Simplify protection flag creation for kernel huge mappings arm64/mm: Change BUG_ON() to VM_BUG_ON() in [pmd|pud]_set_huge() arm64/mm: Identify user instruction aborts arm64/mm: Drop mmap_sem before calling __do_kernel_fault() arm64/mm: Drop task_struct argument from __do_page_fault() arm64/mm: Document write abort detection from ESR arm64/mm: Refactor __do_page_fault() arm64/mm: Drop [PTE|PMD]_TYPE_FAULT Ard Biesheuvel (5): acpi/arm64: ignore 5.1 FADTs that are reported as 5.0 arm64: module: create module allocations without exec permissions arm64/mm: wire up CONFIG_ARCH_HAS_SET_DIRECT_MAP arm64/kprobes: set VM_FLUSH_RESET_PERMS on kprobe instruction pages arm64: bpf: do not allocate executable memory Bartlomiej Zolnierkiewicz (1): arm64: remove redundant 'default n' from Kconfig Catalin Marinas (2): arm64: ARM64_MODULES_PLTS must depend on MODULES Merge branch 'for-next/perf' of git://git.kernel.org/.../will/linux Florian Fainelli (1): arm64: Allow user selection of ARM64_MODULE_PLTS Frank Li (3): dt-bindings: perf: imx8-ddr: add imx8qxp ddr performance monitor drivers/perf: imx_ddr: Add DDR performance counter support to perf MAINTAINERS: Add maintainer entry for the imx8 DDR PMU driver Jayachandran C (1): arm64: Improve parking of stopped CPUs Jeremy Linton (4): ACPI/PPTT: Modify node flag detection to find last IDENTICAL ACPI/PPTT: Add function to return ACPI 6.3 Identical tokens arm_pmu: acpi: spe: Add initial MADT/SPE probing perf: arm_spe: Enable ACPI/Platform automatic module loading Julien Grall (4): arm64/fpsimd: Remove the prototype for sve_flush_cpu_state() arm64/fpsimd: Introduce fpsimd_save_and_flush_cpu_state() and use it arm64/fpsimd: Don't disable softirq when touching FPSIMD/SVE state arm64/cpufeature: Convert hook_lock to raw_spin_lock_t in cpu_enable_ssbs() Julien Thierry (7): arm64: Do not enable IRQs for ct_user_exit arm64: irqflags: Pass flags as readonly operand to restore instruction arm64: irqflags: Add condition flags to inline asm clobber list arm64: Fix interrupt tracing in the presence of NMIs arm64: Fix incorrect irqflag restore for priority masking arm64: irqflags: Introduce explicit debugging for IRQ priorities arm64: Allow selecting Pseudo-NMI again Liu Song (1): arm64: kernel: use aff3 instead of aff2 in comment Mark Brown (2): arm64: Expose ARMv8.5 CondM capability to userspace arm64: Expose FRINT capabilities to userspace Mark Rutland (1): arm64: mm: avoid redundant READ_ONCE(*ptep) Masayoshi Mizuma (1): arm64/mm: Correct the cache line size warning with non coherent device Miles Chen (1): arm64: mm: make CONFIG_ZONE_DMA32 configurable Nick Desaulniers (1): arm64: defconfig: enable CONFIG_RANDOMIZE_BASE Odin Ugedal (1): arm64: Fix comment after #endif Shaokun Zhang (2): drivers: base: cacheinfo: Add variable to record max cache line size arm64: cacheinfo: Update cache_line_size detected from DT or PPTT Sudeep Holla (4): ptrace: move clearing of TIF_SYSCALL_EMU flag to core arm64: add PTRACE_SYSEMU{,SINGLESTEP} definations to uapi headers arm64: ptrace: add support for syscall emulation x86/entry: Simplify _TIF_SYSCALL_EMU handling Wei Li (1): arm64: fix kernel stack overflow in kdump capture kernel jinho lim (1): arm64: rename dump_instr as dump_kernel_instr Documentation/arm64/elf_hwcaps.txt | 8 + .../devicetree/bindings/perf/fsl-imx-ddr.txt | 21 + MAINTAINERS | 7 + arch/arm64/Kconfig | 35 +- arch/arm64/configs/defconfig | 1 + arch/arm64/include/asm/acpi.h | 3 + arch/arm64/include/asm/arch_gicv3.h | 4 +- arch/arm64/include/asm/cache.h | 5 +- arch/arm64/include/asm/cacheflush.h | 3 + arch/arm64/include/asm/cpufeature.h | 6 + arch/arm64/include/asm/daifflags.h | 75 ++- arch/arm64/include/asm/fpsimd.h | 5 +- arch/arm64/include/asm/hwcap.h | 2 + arch/arm64/include/asm/irqflags.h | 79 ++- arch/arm64/include/asm/kvm_host.h | 7 +- arch/arm64/include/asm/pgtable-hwdef.h | 3 +- arch/arm64/include/asm/pgtable-prot.h | 1 -
