Cover letter [Patch 0/6] MIPS Hardware watchpoint support for gdb (version 2).

This is my second take at MIPS watch register support.

Changes from the previous version include:

* Change layout of structures used by ptrace to eliminate holes.

* Use [set|clear]_tsk_thread_flag() and friends instead of racy direct access.

* mips64 support (untested).

* Fix sparse warnings.

For this version of the patch you will need the corresponding gdb patch which can be found here:
