[patch] ia64: remove per_cpu_offset()

[Simon Horman <horms@verge.net.au>]

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.

> -#define per_cpu_offset(x) (__per_cpu_offset(x))
> +#define per_cpu_offset(x) (__per_cpu_offset[x])

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