his e-mail from October you found contains the context showing the
build failure:
i'm pretty sure this breaks on every symbol-prefixed arch. at least,
it broke every Blackfin board:
init/built-in.o: In function `populate_rootfs':
init/initramfs.c:(.init.text+0x2548): undefined reference to
`__initramfs_size'
init/initramfs.c:(.init.text+0x254e): undefined reference to
`__initramfs_size'
make: *** [.tmp_vmlinux1] Error 1

it was caused by changes Michal added post 2.6.36, and then pushed to
Linus without bothering to address the reports sent to him. so it
needs to be in before 2.6.37 is released.
