[PATCH][UPDATED] MIPS: Kprobe support v0.2

[Himanshu Chauhan <hschauhan@nulltrace.org>]

This updated version of patch incorporates some of the comments
from Daney. The list of changes are as follows:
o Instead of separate handler "do_break", do_bp is used to
  track and handle kprobe induced breaks. This cleans up ugly
  ifdef hack.
o Instead of using 0 and 5 code in break, new kprobe specific
  defines (515, 516) have been added and handled.

The use of notify_die could not be dropped because the kprobes
framework installs handlers on notify_die chain.
