What the hell are you doing? Compiling with debugging or something?

The ramfs inode.o file (the only file that ramfs contains) has 376 bytes
of data and 1612 bytes of code. BYTES. The whole final object file with
all the relocation information is

-rw-r--r-- 1 torvalds eng 5734 May 16 10:58 ramfs.o

but out of that 5.5kB, only 2kB are actually linked into the kernel and
are used to _run_.

How do you get it to 140kB? You're doing something _seriously_
wrong. You're off by a factor of 70.
