We now throw all of the machvecs in to .machvec.init and either select one on the command line, or copy out the first (and usually only) one to sh_mv. The rest are freed as usual. This gets rid of all of the silly sh_mv aliasing and makes the selection explicit rather than link-order dependent. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
