i'm not really familiar with the s390 architecture. are the specific
functions declared in a different header or are they not available at
all? in the second case, i'd suggest to disable this driver on this
architecture, as it seems highly unlikely that anyone is going to use
this hardware on this architecture (it would not surprise me, if i'm the
only user of this hardware on linux)

cheers,
tim
