Subject: Re: [RFC 4/7] MIPS: malta: add YAMON-style GT64120 memory map
Date: Fri, 20 Jul 2012 14:01:35 +0400	[thread overview]
Message-ID: <CAA4bVAH9dkYq9QGeS59ftkuC98OUMW-KS5iXC+75Ys9vN0o8fA@mail.gmail.com> (raw)
In-Reply-To: <1342774059-2169-5-git-send-email-antonynpavlov@gmail.com>

Sorry, this patch can't be applied!
It cites diff-formatted text in the comment.
adding extra spaces to this cited text fixes the problem.
