2012-07-17T23:21:30+00:00

Commit acdc0d5ef9dd ('m32r: fix breakage from "m32r: use generic ptrace_resume code"') tried to fix a problem in commit e34112e3966fc ("m32r: use generic ptrace_resume code") by returning values in a function returning void, causing: arch/m32r/kernel/ptrace.c: In function 'user_enable_single_step': arch/m32r/kernel/ptrace.c:594:3: warning: 'return' with a value, in function returning void [enabled by default] arch/m32r/kernel/ptrace.c:598:3: warning: 'return' with a value, in function returning void [enabled by default] arch/m32r/kernel/ptrace.c:601:3: warning: 'return' with a value, in function returning void [enabled by default] arch/m32r/kernel/ptrace.c:604:2: warning: 'return' with a value, in function returning void [enabled by default] Remove the unneeded return values.

ptrace: change signature of arch_ptrace()

2010-10-28T01:03:10+00:00

Fix up the arguments to arch_ptrace() to take account of the fact that @addr and @data are now unsigned long rather than long as of a preceding patch in this series.

m32r: use generic ptrace_resume code

2010-03-12T23:52:39+00:00

Use the generic ptrace_resume code for PTRACE_SYSCALL, PTRACE_CONT, PTRACE_KILL and PTRACE_SINGLESTEP. This implies defining arch_has_single_step in and implementing the user_enable_single_step and user_disable_single_step functions, which also causes the breakpoint information to be cleared on fork, which could be considered a bug fix. Also the TIF_SYSCALL_TRACE thread flag is now cleared on PTRACE_KILL which it previously wasn't, which is consistent with all architectures using the modern ptrace code. The old code only disables the breakpoints on PTRACE_KILL, while after this patch this also happens for PTRACE_CONT and PTRACE_SYSCALL which matches the behaviour of the other architetures. I think this is a bugfixes, but please double verify this is correct.

headers: smp_lock.h redux

2009-07-12T19:22:34+00:00

* Remove smp_lock.h from files which don't need it (including some headers!) * Add smp_lock.h to files which do need it * Make smp_lock.h include conditional in hardirq.h It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT This will make hardirq.h inclusion cheaper for every PREEMPT=n config (which includes allmodconfig/allyesconfig, BTW) Signed-off-by: Alexey Dobriyan Signed-off-by: Linus Torvalds
