From: Alexander Duyck Date: Fri, 16 Nov 2012 21:58:12 +0000 (-0800) Subject: x86/lguest: Use __pa_symbol instead of __pa on C visible symbols X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6a3956bd242926f8956992f6ed7805b0811be003;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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.
