Someone reported binfmt_elf.o wouldn't load because of unresolved symbols,
but didn't report the symbols that were missing (I seem to have deleted
the original mail.)
Turns out it is empty_zero_page and get_user_pages that are missing.
Probably been broken for ages, as binfmt_elf is compiled in for 99.9%
of folks of course.
Patch for i386 against 2.4.17 follows. Other arch may also still be broken,
depending on their definition of ZERO_PAGE and whether or not it uses
empty_zero_page.
Paul.
