Ah, so s390 doesn't yet have the notion of consolemap and supposes
latin1...  Then fine, it's actually simpler, here is a patch.

Samuel

Turn the kernel accent_table into unicode, and extend ioctls KDGKBDIACR
and KDSKBDIACR into their equivalents KDGKBDIACRUC and KDSKBDIACR.

New function int conv_uni_to_8bit(u32 uni) for converting unicode into 8bit
_input_.  No, we don't want to store the translation, as it is potentially
sparse and large.
