Hi all,

[This has been happening for a while, I just missed it :-( ]

After merging the tip tree, today's linux-next build (x86_64 allnoconfig)
produced this warning:

arch/x86/kernel/unwind_orc.c:210:12: warning: 'orc_sort_cmp' defined but not used [-Wunused-function]
210 | static int orc_sort_cmp(const void *_a, const void *_b)
| ^~~~~~~~~~~~
arch/x86/kernel/unwind_orc.c:190:13: warning: 'orc_sort_swap' defined but not used [-Wunused-function]
190 | static void orc_sort_swap(void *_a, void *_b, int size)
| ^~~~~~~~~~~~~

Introduced by commit

f14bf6a350df ("x86/unwind/orc: Remove boot-time ORC unwind tables sorting")
Now fixed via:

22a7fa8848c5: ("x86/unwind/orc: Fix !CONFIG_MODULES build warning")

Will push it out after some testing, should go out with the next
tip:auto-latest version.
Thanks very much! sorry for trouble.
