I think there will have to be at least one more pass at this.

The current design assumes that all debug registers support an identical
set of the I, R, and W bits and Mask.

However sections 8.23 and 8.24 of my

  MIPS32® Architecture For Programmers
Volume III: The MIPS32® Privileged Resource Architecture

indicate that they do not have to uniform.  I will have to augment the
ptrace structures to report the values for each register instead of a
single global value.
