Subject: [PATCH] x86/unwind/orc: Move ORC sorting variables under CONFIG_MODULE
Date: Tue, 28 Apr 2020 02:16:40 -0500

Fix the following warnings seen with !CONFIG_MODULE:

  arch/x86/kernel/unwind_orc.c:29:26: warning: 'cur_orc_table' defined but not used [-Wunused-variable]
     29 | static struct orc_entry *cur_orc_table = __start_orc_unwind;
        |                          ^~~~~~~~~~~~~
  arch/x86/kernel/unwind_orc.c:28:13: warning: 'cur_orc_ip_table' defined but not used [-Wunused-variable]
     28 | static int *cur_orc_ip_table = __start_orc_unwind_ip;
        |             ^~~~~~~~~~~~~~~~
