This is a rework of Steven Walter's syscall tracing patches first posted here: http://lists.infradead.org/pipermail/linux-arm-kernel/2011-November/074454.html I've rebased the patches against the current mainline master branch, as well as implemented several changes based on feedback from Will Deacon and Russell King. v2: - Tested on EABI and OABI. - Removed an instance of the ?: operator in syscall_set_return_value() - Moved #define of NR_syscalls to syscall.h - Changed the test of NR_syscalls vs __NR_syscalls in entry-common.S to .ifne v3: - Added Will Deacon's Reviewed-by line. Code is identical to v2. Wade Farnsworth (3): ARM: add support for the generic syscall.h interface ARM: add TRACEHOOK support ARM: support syscall tracing arch/arm/Kconfig | 2 + arch/arm/include/asm/ptrace.h | 5 ++ arch/arm/include/asm/syscall.h | 97 ++++++++++++++++++++++++++++++++++++ arch/arm/include/asm/thread_info.h | 2 + arch/arm/include/asm/unistd.h | 8 +++ arch/arm/kernel/entry-common.S | 16 +++++- arch/arm/kernel/ptrace.c | 34 +++++++------ arch/arm/kernel/signal.c | 2 + 8 files changed, 149 insertions(+), 17 deletions(-) create mode 100644 arch/arm/include/asm/syscall.h
