Subject: [uml-devel] [PATCH 1/3] uml: use -mcmodel=kernel for x86_64
Date: Sun, 06 Aug 2006 17:47:00 +0200 [thread overview]
Message-ID: <20060806154700.536.32978.stgit@memento.home.lan> (raw)
From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>
We have never used this flag and recently one user experienced a complaining
warning about this (there was a symbol in the positive half of the address space
IIRC). So fix it.
