Well, grepping in the CVS repository shows that there never was an actually consumer of ipi_all() (only #ifdef'ed out ones in ironically the sparc64 code) so it seems to be a good candidate for axing. Generally I can't think of a reason why MI code would want a CPU to send an IPI to itself. Actually, ipi_self() also isn't and never was used in MI code, only in ia64 and powerpc code for testing purposes.
