It seems to be working fine otherwise. The one limitation though is down
to how ftrace works on powerpc -- the mcount call is before a function
sets up its own stackframe. Due to this, we won't ever be able to
account for the stackframe from a leaf function -- but, that's a fairly
minor limitation.
And this is true for x86 as well because it no longer uses mcount, but
uses fentry instead (called before stack setup), but I figured there's
not much we could do about it.
