"size_t" should be an unsigned type according to the C standard.
Thus we should also use this convention in the s390-ccw firmware to avoid
confusion. I checked the sources, and apart from one spot in libc.c, the
code should all be fine with this change.

looks better. I checked all users of size_t and this seems complete.
