Patch from Eric Valette <valette@crf.canon.fr>:
Eric> NB : there is still a bug on PC386 serial line : exit does not Eric> flush the remaining output queue. As this is not a bug in the Eric> driver itself but somewhere in PC386 initialization/termios Eric> relationship it will be part of another patch. Eric> NB2 : As Emmanuel excerced the exception hanlder code, while Eric> porting the SMC driver to the new BSD stack, we found a bug Eric> in the exception handler : it shall not delete the current Eric> thread in case we are running at interrupt level. This will Eric> be part of another patch... So here is the patch. This patch fixes the two problems mentionned above + it use vpath mechanism intead of copying the irq related files in the right directory. This avoid to compile them each time and is more homogenous with other Makefiles.
