Subject: [Qemu-devel] [PULL 04/13] migration: Fix remaining 32 bit compiler errors
Date: Tue, 17 Mar 2015 16:30:26 +0100 [thread overview]
Message-ID: <1426606235-7238-5-git-send-email-quintela@redhat.com> (raw)
In-Reply-To: <1426606235-7238-1-git-send-email-quintela@redhat.com>
From: Stefan Weil <sw@weilnetz.de>
Fix type casts between pointers and 64 bit integers.
Now 32 bit builds are possible again.
