ftrace: Do not pass data to ftrace_dyn_arch_init

2014-03-07T15:06:14+00:00

As the data parameter is not really used by any ftrace_dyn_arch_init, remove that from ftrace_dyn_arch_init. This also removes the addr local variable from ftrace_init which is now unused. Note the documentation was imprecise as it did not suggest to set (*data) to 0.

ftrace: Pass retval through return in ftrace_dyn_arch_init()

2014-03-07T15:06:13+00:00

No architecture uses the "data" parameter in ftrace_dyn_arch_init() in any way, it just sets the value to 0. And this is used as a return value in the caller -- ftrace_init, which just checks the retval against zero. Note there is also "return 0" in every ftrace_dyn_arch_init. So it is enough to check the retval and remove all the indirect sets of data on all archs.

Blackfin: update ftrace_push_return_trace() breakage

2009-09-17T02:10:47+00:00

Commit 71e308a239c updated ftrace_push_return_trace() prototype but didn't update the Blackfin ftrace code, so things broke. Since we don't support the new stuff yet, call it with stub values. Signed-off-by: Mike Frysinger
