this worked. thanks. There was one place in ipv4 that failed compilation with proc_fs disabled. Fixed that. Otherwise everything compiled cleanly.

with procfs disabled, the boot fails, since nash(fedora's startup script) which links with libc.so library has dependencies on /proc. Nash segfaults and so does init. looking for ideas.
