Merge branch 'for-linus' of git://git390.osdl.marist.edu/pub/scm/linux-2.6
* 'for-linus' of git://git390.osdl.marist.edu/pub/scm/linux-2.6: [S390] stacktrace bug. [S390] cio: remove casts from/to (void *). [S390] cio: Remove grace period for vary off chpid. [S390] cio: Use ccw_dev_id and subchannel_id in ccw_device_private [S390] monwriter kzalloc size. [S390] cio: add missing KERN_INFO printk header. [S390] irq change improvements.
