[Qemu-devel] [PATCH 2/2] ivshmem: convert option 'use64' to a bit instea


From: Levente Kurusa
Subject: [Qemu-devel] [PATCH 2/2] ivshmem: convert option 'use64' to a bit instead of integer
Date: Mon, 4 Aug 2014 17:06:21 +0200

It was expecting an integer, however the sole usecase of it just
checked whether it was assigned to or not. Hence, remove integerness,
and add a new bitfield instead.
