This series removes the place holder __ftrace_invalid_address___ from
the available_filter_functions file.

The rewriting of the sorttable.c code to make it more manageable
has already been merged:

  https://git.kernel.org/torvalds/c/c0e75905caf368e19aab585d20151500e750de89

Now this is only for getting rid of the ftrace invalid function place holders.  

Since you asked me to test this on s390: seems to work with
HAVE_BUILDTIME_MCOUNT_SORT enabled; the ftrace selftests still
work as before.

My tests found a bug (forgot to initialize a variable) and I will be
sending a v5 soon.

You may also want to enable: CONFIG_FTRACE_SORT_STARTUP_TEST

That will make ftrace test to see if the mcount table is indeed sorted at
boot up.
