With commit 622240ea8d71 ("vmlinux.lds.h: Adjust symbol ordering in
text output section"), symobls in sections .text.unlikely will be
placed before symbols in .text. This can lead to the misplacement
of _stext, which resides in the .text section, and result in a boot
hang.
Explicitly set _stext to the beginning of text output section.
