[GIT PULL][RESEND] ARM: hw_breakpoint: fixes and improvements

[Will Deacon]

Hi Russell,

I don't think you've pulled this yet, but I've been having
issues with my git server so here's a mirrored address which
is up-to-date. Note that I've made some minor changes to the
final patch since the last pull request.

I'm on holiday from today so if you have any problems, I'll
resolve them in the new year.

Cheers,

Will
