Needs MODVERSIONS=y + MODULE_FORCE_UNLOAD=n.
Thanks for report!

Revert "module: remove the SHF_ALLOC flag on the __versions section."
This reverts commit 9cb610d8e35fe3ec95a2fe2030b02f85aeea83c1.
This was an impressively stupid patch. Firstly, we reset the SHF_ALLOC
flag lower down in the same function, so the patch was useless. Even
better, find_sec() ignores sections with SHF_ALLOC not set, so
it breaks CONFIG_MODVERSIONS=y with CONFIG_MODULE_FORCE_LOAD=n, which
refuses to load the module since it can't find the __versions section.
