From 06837504de7b4883e92af207dbbab4310d0db0ed Mon Sep 17 00:00:00 2001 From: Paolo 'Blaisorblade' Giarrusso Date: Wed, 27 Sep 2006 01:50:27 -0700 Subject: [PATCH] [PATCH] uml: use -mcmodel=kernel for x86_64 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.
