Mspec driver and non-SN platforms?

From: Peter Chubb <>

	If you try to enable mspec when compiling for other than SN,
you get undefined references to uncached_free_page,
per_cpu__sn_hub_info, physical_node_map, and bte_copy.

Maybe the attached patch is needed... which disables fetchop for other
than Altix or generic kernels.  If and when the facility becomes
available on other platforms, it's probably going to need a new driver
(and new CONFIG option) anyway.
