[IA64-SGI] Shub2 BTE address fix
After converting the cpu physical address to shub2 physical addressing, the address was run through TO_PHYS() which clobbered a high node offset bit causing the BTE to fail on shub2 nodes with large memory. This fix corrects that problem. Signed-off-by: Russ Anderson (rja@sgi.com) Signed-off-by: Tony Luck <tony.luck@intel.com>
