Subject: [Qemu-devel] [PATCH 09/40] xenner: kernel: Global data
Date: Mon,  1 Nov 2010 16:01:22 +0100	[thread overview]
Message-ID: <1288623713-28062-10-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1288623713-28062-1-git-send-email-agraf@suse.de>

We need to access global variables from various points in the code. Keep them
in a single file, so we know where they are.
