[PATCH] mspec driver build fix

Browse source 
Fix MSPEC driver to build for non SN2 enabled configs as the driver should
work in cached and uncached modes (no fetchop) on these systems.  In
addition make MSPEC select IA64_UNCACHED_ALLOCATOR, which is required for
it and move it to arch/ia64/Kconfig to avoid warnings on non ia64
architectures running allmodconfig.  Once the Kconfig code is fixed, we can
move it back.
