Cannot compile kernel without Initial RAM filesystem and RAM disk(initramfs/initrd) support

[Johnson, Charles F]

Move to 2.6.23.  It is fixed there.  I ran into exactly the same
problem.

Subject: Cannot compile kernel without Initial RAM filesystem and RAM
disk(initramfs/initrd) support

Hello, I tried to build a custom 2.6.22 kernel on Kubuntu Gutsy without
initramfs support, but the compilation stops with the following error:

init/built-in.o: In function `start_kernel':
/usr/src/linux-source-2.6.22/init/main.c:635: undefined reference to
`early_populate_rootfs'
make[1]: *** [.tmp_vmlinux1] Error 1
make[1]: Leaving directory `/usr/src/linux-source-2.6.22'
make: *** [debian/stamp-build-kernel] Error 2

I can post my .config, if needed. In any case, I don't like the idea to
be forced to enable initramfs.
Any help would be highly appreciated.

Federico
