[PATCH 0/15] kgdb,kdb: proposed merge set for 2.6.36

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

These are the patches for kgdb we have so far which have passed
regression testing during the 2.6.35 cycle. 

The key new features here are:

  * ftdump command for kdb
    - dumps the ftrace buffer for all cpus or an indivdual cpu
  * Individual register read / read in kdb (x86, mips, arm)
  * Generic plumbing for gdb serial register packets 'p' and 'P'
    - implmentations for x86, mips and arm
  * A new console poll driver for the sunhv serial console (sparc)
  * ARM kgdb makes use of die notifiers
  * Optimize gdbserial response packets contaning "thread:"

The remainders of the patches contain miscelaenous cleanups.
optimation for the gdb serial packets which contain the "thread:"

Jason.
