Hi Linus,
some recent changes in the s390 architectures files:
1) Makefile fixes.
2) Add missing include statements.
3) Convert all parametes in the 31 bit emulation wrapper of sys_futex.
4) Remove semicolons after 'fi' in Config.in
5) Fix scheduler defines in system.h
6) Simplifications in qdio.c
blue skies,
Martin.
