Actually, this requires HAVE_DYNAMIC_FTRACE_WITH_ARGS, because without
that, the fregs passed in could be NULL. fregs is guaranteed to be non-NULL
for all archs that have that set. As microblaze doesn't have that set, that
would be the fix.

I'll have to resend this pull request anyway depending on the outcome of
the first commit.
