sparc64: Fix not SRA'ed %o5 in 32-bit traced syscall

2013-10-14T01:14:29Z

[ Upstream commit ab2abda6377723e0d5fbbfe5f5aa16a5523344d1 ] (From v1 to v2: changed comment) On the way linux_sparc_syscall32->linux_syscall_trace32->goto 2f, register %o5 doesn't clear its second 32-bit. Fix that. Signed-off-by: Kirill Tkhai CC: David Miller Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

Pull big execve/kernel_thread/fork unification series from Al Viro: "All architectures are converted to new model. Quite a bit of that stuff is actually shared with architecture trees; in such cases it's literally shared branch pulled by both, not a cherry-pick. A lot of ugliness and black magic is gone (-3KLoC total in this one): - kernel_thread()/kernel_execve()/sys_execve() redesign. We don't do syscalls from kernel anymore for either kernel_thread() or kernel_execve(): kernel_thread() is essentially clone(2) with callback run before we return to userland, the callbacks either never return or do successful do_execve() before returning. kernel_execve() is a wrapper for do_execve() - it doesn't need to do transition to user mode anymore. As a result kernel_thread() and kernel_execve() are arch-independent now - they live in kernel/fork.c and fs/exec.c resp. sys_execve() is also in fs/exec.c and it's completely architecture-independent. - daemonize() is gone, along with its parts in fs/*.c - struct pt_regs * is no longer passed to do_fork/copy_process/ copy_thread/do_execve/search_binary_handler/->load_binary/do_coredump. - sys_fork()/sys_vfork()/sys_clone() unified; some architectures still need wrappers (ones with callee-saved registers not saved in pt_regs on syscall entry), but the main part of those suckers is in kernel/fork.c now." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal: (113 commits) do_coredump(): get rid of pt_regs argument print_fatal_signal(): get rid of pt_regs argument ptrace_signal(): get rid of unused arguments get rid of ptrace_signal_deliver() arguments new helper: signal_pt_regs() unify default ptrace_signal_deliver flagday: kill pt_regs argument of do_fork() death to idle_regs() don't pass regs to copy_process() flagday: don't pass regs to copy_thread() bfin: switch to generic vfork, get rid of pointless wrappers xtensa: switch to generic clone() openrisc: switch to use of generic fork and clone unicore32: switch to generic clone(2) score: switch to generic fork/vfork/clone c6x: sanitize copy_thread(), get rid of clone(2) wrapper, switch to generic clone() take sys_fork/sys_vfork/sys_clone prototypes to linux/syscalls.h mn10300: switch to generic fork/vfork/clone h8300: switch to generic fork/vfork/clone tile: switch to generic clone() ...

sparc64: convert to generic execve

2012-10-16T23:03:12Z

We still have wrappers, but nowhere near as scary as they used to be. I'm not sure how necessary that flushw is now, TBH... Signed-off-by: Al Viro

sparc64: clear syscall_noerror on the entry to syscall, not on the exit

2012-10-14T23:26:52Z

Move that sucker to just before TI_FPDEPTH and replace stb with sth in etrap_save(). Take current_ds to its old place, so that we don't push wsaved into TI_... flags. That allows to lose clearing syscall_noerror on return from syscall. Signed-off-by: Al Viro

sparc64: fix ptrace interaction with force_successful_syscall_return()

we want syscall_trace_leave() called on exit from any syscall; skipping its call in case we'd done force_successful_syscall_return() is broken... Signed-off-by: Al Viro Signed-off-by: David S. Miller

sparc64: Kill off old sys_perfctr system call and state.

People should be using the perf events interfaces, and the way these system call facilities used the %pcr conflicts with the usage of the NMI watchdog and perf events. Signed-off-by: David S. Miller
