This patch adds a driver for subchannels of type chsc. A device /dev/chsc is created which may be used to issue ioctls to: - obtain information about the machine's I/O configuration - dynamically change the machine's I/O configuration via asynchronous chsc commands Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
