Cover letter [RFC Patch 0/9] Hardware Breakpoint interfaces - v2

Hi All,
I'm posting a new revision of the patches for using HW
Breakpoint registers (first version posted y'day:
http://lkml.org/lkml/2008/10/7/127).

This patch includes changes which were agreed upon, following the comments from Alan Stern. The patches which are still marked as RFC (pending much larger discussion and interest) is based on 2.6.27-rc9.

Thanks,
K.Prasad
