Subject: [Qemu-devel] [PATCH -V7 1/3] target-ppc: Update external_htab even when HTAB is managed by kernel
Date: Thu,  7 Nov 2013 20:01:00 +0530	[thread overview]
Message-ID: <1383834662-12473-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)

From: "Aneesh Kumar K.V" <aneesh.kumar@linux.vnet.ibm.com>

We will use this in later patches to make sure we use the right load
functions when copying hpte entries.
