future patch will change create_branch() to check for errors.
For callers that don't care, replace create_branch() with
patch_branch(),
which just creates the branch and patches it directly.
While we're touching all the callers, change to using unsigned int
*, as
this seems to match usage better. That allows (and requires) us to
remove
the volatile in the definition of vector in powermac/smp.c and
mpc86xx_smp.c,
that's correct because now that we're passing vector as an unsigned
int *
the compiler knows that it's value might change across the
patch_branch()
call.
