Thanks Will,

forwarding to linux-parisc@vger.kernel.org so that it gets into parisc patchwork.

I'll queue this patch up for 3.11 if it's OK for you.

The arch_{spin,read,write}_relax macros are not used anywhere in the
kernel and are typically just aliases for cpu_relax().

This patch removes the unused definitions for parisc.
