per_cpu_offset() was added as part of a lockdep patch,
"[PATCH] lockdep: add per_cpu_offset()"
(a875a69f8b00a38b4f40d9632a4fc71a159f0e0d),
but ia64 doesn't have lockdep, nor does it use per_cpu_offset()
anywhere else.
This came up because Yu Lumming noticed that the ia64 version
of per_cpu_offset() actually has a syntax error. Amusing as it seems
to have been in the tree for months.

Dave Miller suggested that rather than fixing the unused code it would be
better to just remove it all together.

NAK for now.
I'm trying to add lockdep , so please don't delete it until it could
be proved really useless...
Please don't hurry...
