There is an unnecessary disagreement among architectures over what symbols
should be used to mark section and image boundaries. We could reasonably
agree on at least _start/_end and _stext/_etext I think. This would allow
functions like is_kernel_text() to become generic, and make it obvious which
labels kexec should be using.
