Hi,

here's the second revision of the virtual channel subsystem support for
s390.

I changed the representation of the channel subsystem, introducing channel
subsystem images, which brings it closer to the actual implementation. A
new ioctl for adding a new channel subsystem image has also been introduced.

Cornelia Huck (7):
s390/kvm: Support for I/O interrupts.
s390/kvm: Add support for machine checks.
s390/kvm: In-kernel handling of I/O instructions.
s390: Move css limits from drivers/s390/cio/ to include/asm/.
s390: Make some css-related structures usable by non-cio code.
s390/kvm: Base infrastructure for enabling capabilities.
s390/kvm: In-kernel channel subsystem support.
