According to Tejun the problem is just cosmetic (i.e. causes build
warnings), since the functions affected aren't being used (yet) on
ia64. So feel free to drop the patch again, given that he has a patch
queued to address the issue by renaming the arch variable.

I wonder though why that code is being built on ia64 at all if it's not
being used (i.e. why it doesn't depend on a CONFIG_*, HAVE_*, or
NEED_* manifest constant).
