This patch results in the following build error when trying to build
xtensa:tinyconfig.

WARNING: modpost: vmlinux: section mismatch in reference: strcpy.isra.0+0x14 (section: .text.unlikely) -> initcall_level_names (section: .init.data)
ERROR: modpost: Section mismatches detected.

Unfortunately, reverting it is not possible due to conflicts,
so I can not confirm the bisect results.

Bisect log attached.
