From 6b39271746de131366a14bcf04f5740cdc4abdef Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Mon, 22 Apr 2013 14:10:42 +0930 Subject: lguest: map Switcher below fixmap. Now we've adjusted all the code, we can simply set switcher_addr to wherever it needs to go below the fixmaps, rather than asserting that it should be so. With large NR_CPUS and PAE, people were hitting the "mapping switcher would thwack fixmap" message.
