This patch series also adds x86_64 arch specific support as an example consumer of the new infrastructure. The new interface consists of: 1) int is_compat_task(void); - most arches seem to have this already 2) unsigned long arch_compat_syscall_addr(int nr); - returns a pointer to the compat syscall entry corresponding to syscall 'nr' 3) int NR_syscalls_compat; - number of entries in the compat syscall table. Thus, arches that set CONFIG_FTRACE_SYSCALLS and CONFIG_COMPAT are going to need to implement the above interfaces in order to build. Thus, I'm 'cc arch maintainers. Naming. I've also introduced a couple of new syscall macros: ARCH_COMPAT_SYSCALL_DEFINE#N() COMPAT_SYSCALL_DEFINE#N() These tack on, "arch_compat_sys" and "compat_sys" respectively, to the beginning of the compat syscall names. thanks, -Jason Jason Baron (11): x86: add NR_syscalls_compat, make ia32 syscall table visible x86: add arch_compat_syscall_addr() tracing: remove syscall bitmaps in preparation for compat support tracing: add tracing support for compat syscalls syscalls: add ARCH_COMPAT_SYSCALL_DEFINE() x86, compat: convert ia32 layer to use ARCH_COMPAT_SYSCALL_DEFINE#N() syscalls: add new COMPAT_SYSCALL_DEFINE#N() macro compat: convert to use COMPAT_SYSCALL_DEFINE#N() compat: convert fs compat to use COMPAT_SYSCALL_DEFINE#N() macros tags: recognize syscalls cleanup: remove arg from TRACE_SYS_ENTER_PROFILE_INIT() macro Heiko Carstens (1): compat: have generic is_compat_task for !CONFIG_COMPAT arch/s390/include/asm/compat.h | 7 -- arch/s390/kernel/ptrace.c | 2 +- arch/s390/kernel/setup.c | 2 +- arch/s390/mm/mmap.c | 2 +- arch/x86/ia32/ia32entry.S | 53 ++++++++------- arch/x86/ia32/sys_ia32.c | 106 ++++++++++++++-------------- arch/x86/include/asm/compat.h | 2 + arch/x86/kernel/ftrace.c | 11 +++ drivers/s390/block/dasd_eckd.c | 2 +- drivers/s390/block/dasd_ioctl.c | 1 + drivers/s390/char/fs3270.c | 1 + drivers/s390/char/vmcp.c | 1 + drivers/s390/cio/chsc_sch.c | 1 + drivers/s390/scsi/zfcp_cfdc.c | 1 + fs/compat.c | 147 +++++++++++++++++++-------------------- include/linux/compat.h | 9 +++ include/linux/syscalls.h | 70 ++++++++++++------- include/trace/syscall.h | 8 ++ kernel/compat.c | 106 ++++++++++++++--------------- kernel/trace/trace.h | 2 + kernel/trace/trace_syscalls.c | 101 +++++++++++++++++++-------- scripts/tags.sh | 8 ++- 22 files changed, 369 insertions(+), 274 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
