tracing: Unify arch_syscall_addr() implementations

2010-02-17T12:07:21Z

Most implementations of arch_syscall_addr() are the same, so create a default version in common code and move the one piece that differs (the syscall table) to asm/syscall.h. New arch ports don't have to waste time copying & pasting this simple function. The s390/sparc versions need to be different, so document why. Signed-off-by: Mike Frysinger Acked-by: David S.

tree-wide: Assorted spelling fixes

2010-02-09T10:13:56Z

In particular, several occurances of funny versions of 'success', 'unknown', 'therefore', 'acknowledge', 'argument', 'achieve', 'address', 'beginning', 'desirable', 'separate' and 'necessary' are fixed. Signed-off-by: Daniel Mack Cc: Joe Perches Cc: Junio C Hamano Signed-off-by: Jiri Kosina

tracing/documentation: Cover new frame pointer semantics

2010-01-26T22:00:39Z

Update the graph tracer examples to cover the new frame pointer semantics (in terms of passing it along). Move the HAVE_FUNCTION_GRAPH_FP_TEST docs out of the Kconfig, into the right place, and expand on the details.

tracing/documentation: Fix a typo in ftrace.txt

2010-01-26T21:59:33Z

'ftrace' is no longer the name of the function tracer, to activate the function trace 'echo function > current_tracer' is to be used instead of 'echo ftrace > current_tracer'. Update the documentation to reflect the current implementation. Signed-off-by: Yang Hongyang LKML-Reference: <4B5D0BA8.20106@cn.fujitsu.com> Signed-off-by: Steven Rostedt

kprobetrace, doc: Add the explanation to remove probe points

2010-01-20T06:18:15Z

Latest kprobetrace can remove probe points selectively, thus the documentation should be updated too. Signed-off-by: KOSAKI Motohiro Signed-off-by: Masami Hiramatsu Cc: systemtap Cc: DLE LKML-Reference: <20100119023512.31880.35535.stgit@localhost6.localdomain6> Signed-off-by: Ingo Molnar

kprobetrace, doc: Shell needs single quote to use $ character

2010-01-20T06:18:14Z

Shell interprets $val as shell variable, thus we need quote if we use the echo command. Signed-off-by: KOSAKI Motohiro Signed-off-by: Masami Hiramatsu Cc: systemtap Cc: DLE LKML-Reference: <20100119023505.31880.17367.stgit@localhost6.localdomain6> Signed-off-by: Ingo Molnar

tracing/kprobe: Drop function argument access syntax

2010-01-13T09:09:12Z

Drop function argument access syntax, because the function arguments depend on not only architecture but also compile-options and function API. And now, we have perf-probe for finding register/memory assigned to each argument.
