From fe33f6f1525113ab0bae416966209438e7a31987 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Fri, 26 Jan 2007 00:57:12 -0800 Subject: [PATCH] [PATCH] Fix UML on non-standard VM split hosts This fixes UML on hosts with non-standard VM splits. We had changed the config variable that controls UML behavior on such hosts, but not propogated the change everywhere. In particular, the values of STUB_CODE and STUB_DATA relied on the old variable. I also reformatted the HOST_VMSPLIT_3G help to make it more standard. Spotted by uml@flonatel.org.
