From 6a3956bd242926f8956992f6ed7805b0811be003 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Fri, 16 Nov 2012 13:58:12 -0800 Subject: [PATCH] x86/lguest: Use __pa_symbol instead of __pa on C visible symbols The function lguest_write_cr3 is using __pa to convert swapper_pg_dir and initial_page_table from virtual addresses to physical. The correct function to use for these values is __pa_symbol since they are C visible symbols.
