[git pull] kgdb 2.6.27 merge

[Jason Wessel]

Linus, please pull kgdb the kgdb git tree.

Summary:

 - Add ARCH=arm kgdb support
 - Add ARCH=powerpc kgdb support
 - Add 2 more rs232 polled drivers for use with kgdboc
 - Remove Kconfig option for a non-merged architecture

Details:

The ARCH=arm support was reviewed by rmk and changes were made during
the 2.6.26 development cycle and it has been in the linux-next tree
for some time.  The original author has also acked this work now.

The powerpc kgdb code removes the left over pieces of the old ARCH=ppc
kgdb stub.

The kgdb test suite is known to pass correctly arm and powerpc.

Jason.
