Subject: [PATCH 5/6] Scheduler support for HARDWARE_WATCHPOINTS.
Date: Mon, 28 Apr 2008 18:39:00 -0700	[thread overview]
Message-ID: <48167C34.8080409@avtrex.com> (raw)
In-Reply-To: <48167832.3090103@avtrex.com>

Scheduler support for HARDWARE_WATCHPOINTS.

Here we hook up the scheduler.  Whenever we switch to a new process,
we check to see if the watch registers should be installed, and do it
if needed.
