Subject: Re: [PATCH -v2 9/9] x86: handle HW IOMMU initialization failure gracely
Date: Tue, 10 Nov 2009 12:27:23 +0100 [thread overview]
Message-ID: <20091110112723.GA24190@elte.hu> (raw)
In-Reply-To: <1257849980-22640-10-git-send-email-fujita.tomonori@lab.ntt.co.jp>
this patch needed the fixlet below. (it could be cleaned up later
perhaps to not need the #ifdef - but wanted to keep it simple for now.)
