[PATCH 0/3] ftrace: updates for tip

[Steven Rostedt]

Ingo,

The first patch here is to disable the branch tracer on ALPHA.
There has been several reports that the branch tracer breaks the
compile on ALPHA. Alpha uses ifs extern inlines, and the injecting
of static elements breaks the build.

The next patch fixes the selecting of a tracer for bootup.
Now you can select the default tracer from the kernel command line.

i.e.

  ftrace=function

Will start the function tracer as soon as it is registered.

Now that we have the kernel command line tracer selection working
we can use it for he boot "initcall" tracer. Instead of having the
initcall tracer disable selftests, it now needs to be selected
in the kernel command line as the default tracer to be implemented.
This means we can keep both selftest and boot initcall tracer configured
at the same time.

  ftrace=initcall

Will now enable the boot initcall tracer. No need to recompile.
