[rhn-users] kernel update (2.4.20-13 & 18) missing files (binfmt_coff.o)

["Chris" <chris zenman com au>]

When I updated the kernel to 2.4.20-13.8 and then to 2.4.20-18.8, the file
/lib/modules/2.4.20*/kernel/fs/binfmt_coff.o is missing. I tried copying the
one from the previous version that had it, but it's not compatible.

How do I get or build this file?
