From 93a2cdff98243df06bafd3c4f3b31b38f0d0fe3e Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Mon, 22 Apr 2013 14:10:38 +0930 Subject: lguest: assume Switcher text is a single page. ie. SHARED_SWITCHER_PAGES == 1. It is well under a page, and it's a minor simplification: it's nice to have *one* simplification in a patch series!
