Merge tag 'for_linux-3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jwessel/kgdb

Pull KGDB/KDB/usb-dbgp fixes and cleanups from Jason Wessel:
 "There are no new features, those will be delayed to the 3.7 window.
  There are only fixes/cleanup against the usual kernel churn and we are
  removing more lines than we add:

   - usb-dbgp - increase the controller wait time to come out of halt.
   - kdb - Remove unused KDB_FLAG_ONLY_DO_DUMP code and cpu in more prompt
   - debug core - pass NMI type on archs that provide NMI types"

  kernel/debug: Make use of KGDB_REASON_NMI
