Impact: 32-bit should use logical version there are two version: for default_send_IPI_mask_sequence/allbutself one in ipi.h and one in ipi.c for 32bit it seems .h version overwrote ipi.c for a while. restore it so 32 bit could use its old logical version. also remove dupicated functions in .c Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
