Yesterday I submitted a patch that introduces a 'uv.h' header file for
ia64 and eliminates the ia64 build error. Link to any one of the following
to see the patch.

	http://marc.info/?l=linux-ia64&m=123419673126499&w=2
	http://marc.info/?l=linux-next&m=123419673226503&w=2
	http://marc.info/?l=linux-kernel&m=123419682026636&w=2

That is the preferred solution to this problem.
