2020-08-14sh: stacktrace: Remove stacktrace_ops.stack()Geert Uytterhoeven1-7/+0
The SH implementation never called stacktrace_ops.stack(). Presumably this was copied from the x86 implementation. Hence remove the method, and all implementations (most of them are dummies). Signed-off-by: Geert Uytterhoeven <[email protected]> Signed-off-by: Rich Felker <[email protected]>
2019-04-14sh/stacktrace: Remove the pointless ULONG_MAX markerThomas Gleixner1-4/+0
Terminating the last trace entry with ULONG_MAX is a completely pointless exercise and none of the consumers can rely on it because it's inconsistently implemented across architectures. In fact quite some of the callers remove the entry and adjust stack_trace.nr_entries afterwards.

2017-03-02sched/headers: Prepare for new header dependencies before moving code to ↵Ingo Molnar1-0/+1
<linux/sched/debug.h> We are going to split <linux/sched/debug.h> out of <linux/sched.h>, which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder <linux/sched/debug.h> file that just maps to <linux/sched.h> to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

2011-05-23sh: remove warning and warning_symbol from struct stacktrace_opsRichard Weinberger1-13/+0
Both warning and warning_symbol are nowhere used. Let's get rid of them. Signed-off-by: Richard Weinberger <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2009-08-15sh: stacktrace: Properly terminate the trace entry buffer.Paul Mundt1-0/+4
This inserts a ULONG_MAX entry at the end of the valid entries in the stack trace buffer so the default code doesn't need to scan to the end of available slots. This also makes the trace buffer termination behaviour consistent with the other architectures. Signed-off-by: Paul Mundt <[email protected]>
2009-08-15sh: stacktrace: Add reliability checks in address saving ops.Paul Mundt1-0/+6
This adopts the reliability checks from the x86 stacktrace code so known bad addresses are not recorded in the stack trace buffer. Signed-off-by: Paul Mundt <[email protected]>
2009-08-13sh: Use the new stack unwinder APIMatt Fleming1-2/+3
Instead of implementing our own stack unwinder via dump_trace() we should use the new stack unwinder API because it is more modular. This change allows us to decouple the interface for generating stacktraces from the implementation of a stack unwinder.
