Hi, Jeff, Sam!

I just pulled from Linus-tree, and got the following error when building uml.

$ make defconfig ARCH=um
/home/wangcong/projects/linux-2.6/arch/um/Makefile-i386:32: /home/wangcong/projects/linux-2.6/arch/i386/Makefile.cpu: No such file or directory
make: *** No rule to make target `/home/wangcong/projects/linux-2.6/arch/i386/Makefile.cpu'.  Stop.

Is this a known problem? Yesterday's Linus-tree was fine.

Regards.

Thanks, Al.

With your patch, it works fine.

Jeff, could you please consider pushing this and Al's another patch[1] into Linus-tree? UML in Linus-tree can't work for a long time. ;(
