Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux into next
Pull arm64 updates from Catalin Marinas: - Optimised assembly string/memory routines (based on the AArch64 Cortex Strings library contributed to glibc but re-licensed under GPLv2) - Optimised crypto algorithms making use of the ARMv8 crypto extensions (together with kernel API for using FPSIMD instructions in interrupt context) - Ftrace support - CPU topology parsing from DT - ESR_EL1 (Exception Syndrome Register) exposed to user space signal handlers for SIGSEGV/SIGBUS (useful to emulation tools like Qemu) - 1GB section linear mapping if applicable - Barriers usage clean-up - Default pgprot clean-up Conflicts as per Catalin. * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (57 commits) arm64: kernel: initialize broadcast hrtimer based clock event device arm64: ftrace: Add system call tracepoint arm64: ftrace: Add CALLER_ADDRx macros arm64: ftrace: Add dynamic ftrace support arm64: Add ftrace support ftrace: Add arm64 support to recordmcount arm64: Add 'notrace' attribute to unwind_frame() for ftrace arm64: add __ASSEMBLY__ in asm/insn.h arm64: Fix linker script entry point arm64: lib: Implement optimized string length routines arm64: lib: Implement optimized string compare routines arm64: lib: Implement optimized memcmp routine arm64: lib: Implement optimized memset routine arm64: lib: Implement optimized memmove routine arm64: lib: Implement optimized memcpy routine arm64: defconfig: enable a few more common/useful options in defconfig ftrace: Make CALLER_ADDRx macros more generic arm64: Fix deadlock scenario with smp_send_stop() arm64: Fix machine_shutdown() definition arm64: Support arch_irq_work_raise() via self IPIs ...
