It is matter of days, new mmotm doesn't work either, older did.

Me yes.

No, only some of arch/x86/kernel/something.o.
arch/x86/kernel/ itself is OK.

Doesn't work:
arch/x86/kernel/head64.o
arch/x86/kernel/head_64.o
Works:
arch/x86/kernel/module_64.o
arch/x86/kernel/msr.o
arch/x86/kernel/rtc.o

Doesn't work with
$ make O=../a/ttt/ SUBARCH=i386 arch/x86/kernel/head32.o
and defconfig either here.

I'm at mmotm 2009-02-20-15-52 which is based on
aa0f1f110f4cbbbb83fbac36f71651b232cd8b32
from next/master.

Yup :P.
