Hi all,

I found a bit strange thing happens now --
plain

make arch/x86/kernel/head64.o

doesn't work anymore. Instead of compiling
_just_ this file I've got the following:

I've done make allyesconfig previously.
I don't understand what I'm doing wrong... :(

I should work...

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

Do you have CONFIG_64BIT set in your config?

Me yes.

Does it behave strange also for files in kernel/?

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

Can you postthe output of a "make V=1 arch/x86/kernel/head64.o"

I cannot try to reproduce locally as my current setup does not
support 64 bit x86 builds.

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.

Does anyone else see the same?

Yup :P.
