Date: Sun, 06 Aug 2006 17:47:00 +0200 From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@...oo.it> To: Andrew Morton <akpm@...l.org> Cc: Jeff Dike <jdike@...toit.com>, user-mode-linux-devel@...ts.sourceforge.net, linux-kernel@...r.kernel.org Subject: [PATCH 1/3] uml: use -mcmodel=kernel for x86_64 From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@...oo.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.
