Subject: [PATCH 0/9] breakpoint: Rework arch validation
Date:   Sun,  6 May 2018 21:19:46 +0200
Message-Id: <1525634395-23380-1-git-send-email-frederic@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This is the first round of breakpoint code rework and cleanup. Here we
split up architecture validation and commit so that we don't mess up
with architecture internals in case attributes are rejected or slot
can't be reserved. It also unconfuse the code in general.

Thanks,
