[PATCH 0/2] mips kgdb support rev 2

[Jason Wessel]

This is rev 2 of the kgdb support.  Based on comments from Ralf, I elected
to switch to die notification and entirely remove the trap_low, which
was not getting dynamically unregistered in the first place after kgdb
was unconfigured.

This greatly simplified the kgdb implementation for mips, and allowed for
the deprecation of a couple more headers and a large chunk of assembly
code.

Jason.
