[git pull] kgdb core and rs232 I/O drivers

[Jason Wessel <jason.wessel@windriver.com>]

The kgdb tree has been collapsed review.  It includes
the kgdb core, the x86 arch, the kgdb8250 uart driver
and the kgdb console sharing driver.

Since the last time the kgdb patches were posted to LKML
several months ago, the kgdb core has undergone some
significant cleanup, as well as the kgdb I/O driver
interface.

All the kgdb hooks are initialized dynamically only when a
kgdb I/O module is configured. When not configured
kgdb will not exist in any kernel execution path.

Further comments are certainly welcome.

Thanks,
Jason.
