As an excellent indicator of how much testing the DSP code gets, a couple of rather glaring bugs in the DSP save/restore paths were found: - In the DSP restore case a0 needs to be popped off before a0g, or the value of a0g is clobbered by the MSB of a0 in the case of sign extension. - Beyond that, the save and restore orders were out of sync, so this fixes that up as well. At the same time, we switch over to using movs.l for both the save and restore of the general DSP registers as opposed to using sts.l (which was initially put in place to work around a bug in ancient binutils versions which the kernel no longer supports).
