I've managed to do some preliminary testing using the GDB work
in progress and found a few coding howlers. Rather than submit
a new patchset, I'll keep an up-to-date patch series, rebased
against the latest mainline tag here:

http://www.linux-arm.org/git?p=linux-2.6-wd.git;a=shortlog;h=refs/heads/hw-breakpoint

Once the GDB work is complete, I'll submit v4 to this list.

Cheers,

Will
