From 406a590ba105bfb7b67952f0a5f948e0d374e03e Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Mon, 22 Apr 2013 14:10:37 +0930 Subject: lguest: prepare to make SWITCHER_ADDR a variable. We currently use the whole top PGD entry for the switcher, but that's hitting the fixmap in some configurations (mainly, large NR_CPUS). Introduce a variable, currently set to the constant.
