From 02edeb586ae4cdd17778923674700edb732a4741 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Sat, 3 Sep 2005 15:57:33 -0700 Subject: [PATCH] uml: mark SMP on UML/x86_64 as broken Noticed by Al Viro - SMP on x86_64 is fundamentally broken due to UML's reuse of the host arch's percpu stuff. This is OK on x86, but the x86_64 pda stuff just won't work for UML.
