From: Guo Ren <guoren@xxxxxxxxxxxxxxxxx> Here are the patchess for the next linux version. Add features (seccomp-filter, err-injection, top-down&random mmap-layout, irq_work, show_ipi, context-tracking), and fixup (kprobe_on_ftrace, ...), Optimize (fault print, ...). I think we'll finish most of features for arch/csky this year :) Guo Ren (12): csky: Add SECCOMP_FILTER supported csky: Add cpu feature register hint for smp csky: Fixup duplicated restore sp in RESTORE_REGS_FTRACE csky: Fixup kprobes handler couldn't change pc csky: Add support for function error injection csky: Optimize the trap processing flow csky: Use top-down mmap layout csky: Set CONFIG_NR_CPU 4 as default csky: Fixup warning by EXPORT_SYMBOL(kmap) csky: Add irq_work support csky: Add arch_show_interrupts for IPI interrupts csky: Add context tracking support Tobias Klauser (1): csky: remove unusued thread_saved_pc and *_segments functions/macros arch/csky/Kconfig | 29 +++- arch/csky/abiv2/inc/abi/entry.h | 3 - arch/csky/abiv2/mcount.S | 4 +- arch/csky/include/asm/Kbuild | 1 + arch/csky/include/asm/bug.h | 3 +- arch/csky/include/asm/irq_work.h | 11 ++ arch/csky/include/asm/processor.h | 6 - arch/csky/include/asm/ptrace.h | 7 + arch/csky/include/asm/thread_info.h | 2 +- arch/csky/kernel/entry.S | 26 +++ arch/csky/kernel/process.c | 10 -- arch/csky/kernel/ptrace.c | 37 +---- arch/csky/kernel/smp.c | 62 ++++++- arch/csky/kernel/traps.c | 223 +++++++++++++++++--------- arch/csky/lib/Makefile | 1 + arch/csky/lib/error-inject.c | 10 ++ arch/csky/mm/fault.c | 10 +- arch/csky/mm/highmem.c | 2 - tools/testing/selftests/seccomp/seccomp_bpf.c | 13 +- 19 files changed, 317 insertions(+), 143 deletions(-) create mode 100644 arch/csky/include/asm/irq_work.h create mode 100644 arch/csky/lib/error-inject.c -- 2.7.4
