Ah sorry, that was only what I expected. I haven't asked the maintainer yet.
I'm asking now.

I'm file with that. In fact I don't have strong opinion here
as long as the linux ia64 maintainer, Tony, is fine.

Tony, what do you think about the following patch?
- path
  asm-ia64/pvclock-abi.h versus asm-ia64/xen/pvclock-abi.h
- including asm-x86/pvclock-abi.h

Subject: [PATCH] ia64/xen: add a neccessary header file to copmle include/xen/interface/xen.h

Create include/asm-ia64/pvclock-abi.h to compile which includes
include/asm-x86/pvclock-abi.h because ia64/xen uses same struture.
Hopefully include/asm-x86/pvclock-abi.h would be moved to somewhere
more generic.
