Subject: [PATCH 3/5] powerpc: Use the XDABR hcall
Date: Thu, 6 Sep 2012 15:17:49 +1000 [thread overview]
Message-ID: <1346908671-7464-3-git-send-email-mikey@neuling.org> (raw)
In-Reply-To: <1346908671-7464-1-git-send-email-mikey@neuling.org>
We never use the XDABR hcall since we check for DABR hcall first.
XDABR syscall is better since it allows us to also set the DABRX.
