[IA64-SGI] Altix SN add support for slots in geoid_t locator
This patch against ia64-test-2.6.12 is needed for forthcoming Altix chipsets. It renames geoid_any_t to geoid_common_t and splits the 8bit 'slab' field into two 4bit fields for 'slab' and 'slot'. Similar changes in the Altix SAL will retain backward compatibility for old kernels. Signed-off-by: Mark Goodwin <markgw@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
