Subject: [PATCH] x86/unwind/orc: fix unused function warnings
Without CONFIG_MODULES, these two variables are unused:
arch/x86/kernel/unwind_orc.c:29:26: error: 'cur_orc_table' defined but not used [-Werror=unused-variable]
29 | static struct orc_entry *cur_orc_table = __start_orc_unwind;
| ^~~~~~~~~~~~~
arch/x86/kernel/unwind_orc.c:28:13: error: 'cur_orc_ip_table' defined but not used [-Werror=unused-variable]
28 | static int *cur_orc_ip_table = __start_orc_unwind_ip;
| ^~~~~~~~~~~~~~~~
Move them into the #ifdef section.
Fixes: 153eb2223c79 ("x86/unwind/orc: Convert global variables to static")
