[GIT PULL] kgdb,kdb for 2.6.36 (1 of 2)

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

Linus, please pull the for_linus branch which contains all the core
kgdb and kdb changes intended for the 2.6.36 kernel.

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

The key new features here are:

  * ftdump command for kdb
    - dumps the ftrace buffer for all cpus or an individual cpu
  * Individual register read / write in kdb (x86, mips, arm)
  * Generic plumbing for gdb serial register packets 'p' and 'P'
    - implementations for x86, mips and arm
  * ARM kgdb makes use of die notifiers
  * Optimize gdbserial response packets containing "thread:"

The remainder of the patches contain miscellaneous cleanups.

Jason.
