[GIT PULL] kgdb/kdb tree for 2.6.37

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

Linus, please pull the for_linus branch to pick up the latest updates
for kgdb/kdb.

git://git.kernel.org/pub/scm/linux/kernel/git/jwessel/linux-2.6-kgdb.git for_lin
us

This pull request comes a few days into the merge window because I was
waiting for the rcu tree to be merged so the debug core specific
patches created back in August could make use of the new rcu stall
detector API.

Summary of changes: 
  * Fixed the ability to dynamically register a kdb shell command from
    a kernel module
  * Exiting kgdb/kdb will reset the RCU stall detector
  * The locking algorithm for multi cpu systems was simplified to use
    2 spinlocks instead of multiple atomic counter arrays the size of
    NR_CPUS.
  * Some minor bug fixes for edge cases and a few code cleanups 

Thanks,
Jason.
