Thanks, I've re-written this as:

- On the S390 architecture PCI BAR spaces are not disjunctive, as such
- the PCI bar is required on a series of otherwise asm generic PCI
- routines, as such S390 requires itw own implemention for these
- routines.
+ On the S390 architecture PCI BAR spaces may overlap with each other,
+ because of this the PCI bar is required on a series of otherwise asm
+ generic PCI routines and this in turn requires S390 to provide its
+ own implementation for these routines.
