topology: alternate fix for ia64 tiger_defconfig build breakage
Define stubs for the numa_*_id() generic percpu related functions for non-NUMA configurations in <asm-generic/topology.h> where the other non-numa stubs live. Fixes ia64 !NUMA build breakage -- e.g., tiger_defconfig Back out now unneeded '#ifndef CONFIG_NUMA' guards from ia64 smpboot.c Signed-off-by: Lee Schermerhorn <lee.schermerhorn@hp.com> Tested-by: Tony Luck <tony.luck@intel.com> Acked-by: Tony Luck <tony.luck@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
