Stefan Weinhuber 9062014cb6 [S390] cio: reduce memory consumption of itcw structures
Any list of indirect data adresses (TIDAL) used by a TCW must not
cross a page boundary. The original itcw implementation complies with
this restriction by allocating allmost twice as much memory as
actually needed, so that in any case there is enough room for the full
TIDAL, either above or below the page boundary.
This patch implements an alternative method, by using a TTIC TIDAW to
connect TIDAL parts below and above a page boundary.
