Merge tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King: - Fix BSS size calculation for LLVM - Improve robustness of kernel entry around v7_invalidate_l1 - Fix and update kprobes assembly - Correct breakpoint overflow handler check - Pause function graph tracer when suspending a CPU - Switch to generic syscallhdr.sh and syscalltbl.sh - Remove now unused set_kernel_text_r[wo] functions - Updates for ptdump (__init marking and using DEFINE_SHOW_ATTRIBUTE) - Fix for interrupted SMC (secure) calls - Remove Compaq Personal Server platform * tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: footbridge: remove personal server platform ARM: 9075/1: kernel: Fix interrupted SMC calls ARM: 9074/1: ptdump: convert to DEFINE_SHOW_ATTRIBUTE ARM: 9073/1: ptdump: add __init section marker to three functions ARM: 9072/1: mm: remove set_kernel_text_r[ow]() ARM: 9067/1: syscalls: switch to generic syscallhdr.sh ARM: 9068/1: syscalls: switch to generic syscalltbl.sh ARM: 9066/1: ftrace: pause/unpause function graph tracer in cpu_suspend() ARM: 9064/1: hw_breakpoint: Do not directly check the event's overflow_handler hook ARM: 9062/1: kprobes: rewrite test-arm.c in UAL ARM: 9061/1: kprobes: fix UNPREDICTABLE warnings ARM: 9060/1: kexec: Remove unused kexec_reinit callback ARM: 9059/1: cache-v7: get rid of mini-stack ARM: 9058/1: cache-v7: refactor v7_invalidate_l1 to avoid clobbering r5/r6 ARM: 9057/1: cache-v7: add missing ISB after cache level selection ARM: 9056/1: decompressor: fix BSS size calculation for LLVM ld.lld
