Well, it's not actuall working in these sense of that it isn't and never
has been in mainline and also is utterly bit-rotted.  I have absolutely
no interested in keeping a tracing implementation away from mainline
that just works out of the box (not just on x86 but also on powerpc and
others) just because ia64 is too slow to get modern features.

And it's not like we got any interesting amount of IA64 users, nor have
does SGI who seems to be interested in IA64 do a lot of patches to XFS.
