UBUNTU: SAUCE: s390: kernel message catalog

BugLink: http://bugs.launchpad.net/bugs/1628889
Add support for automatic message tags to the printk macro
families dev_xyz and pr_xyz. The message tag consists of a
component name and a 24 bit hash of the message text. For
each message that is documented in the included kernel message
catalog a man page can be created with a script (which is
included in the patch). The generated man pages contain
explanatory text that is intended to help understand the
messages.

Note that only s390 specific messages are prepared
appropriately and included in the generated message catalog.

This patch is optional as it is very unlikely to be accepted
in upstream kernel, but is recommended for all distributions
which are built based on the 'Development stream'
