* ftrace: Do not pass data to ftrace_dyn_arch_initJiri Slaby2014-03-071-1/+1
| | | | | | | | | | | | | | | | | 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()Jiri Slaby2014-03-071-3/+0
| | | | | | | | | | | | | | | | | 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.

| | | | | | | | 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 <vapier@gentoo.org>
