2013-03-08s390/css: Fix subchannel detectionChristian Borntraeger
We have to consider the m bit to find the real channel subsystem when determining the last subchannel. If we fail to take this into account, removal of a subchannel in the middle of a big list of devices will stop device detection after a reboot.

2013-02-13s390: Fix handling of iscs.Cornelia Huck
There are two ways to express an interruption subclass: - As a bitmask, as used in cr6. - As a number, as used in the I/O interruption word. Unfortunately, we have treated to I/O interruption word as if it contained the bitmask as well, which went unnoticed so far as - (queued-for-next) kvm made the same mistake, and - Linux guest kernels don't check the isc value in the I/O interruption word for subchannel interrupts. Make sure that we treat the I/O interruption word correctly. Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2013-01-29s390: css error codes.Cornelia Huck
Changed error codes in the channel subsystem / virtio-ccw code (-EOPNOTSUPP -> -ENOSYS, -ERESTART -> -EINPROGRESS). This should hopefully fix building on mingw32.
