Date: Wed, 10 Mar 2010 16:01:10 +0000 [thread overview]
Message-ID: <1268236874-7877-1-git-send-email-will.deacon@arm.com> (raw)

Changes from the previous version include:
- Based on 2.6.33
- Removal of self-modifying code to access the debug registers

- Removal of .name field from struct arch_hw_breakpoint and associated
symbol resolution [following comments made about patches for PPC].
All comments welcome [the last submission didn't attract any!].
