I have skimmed the patches - they all looked good to me.
Everyting that cleans up arch/um/Makefile is good!

I you respin them you can add my:

Acked-by: Sam Ravnborg <sam@ravnborg.org>

The asm-offsets.h that um picks us is the one generated by um.
So we still need to add a dummy file in arch/um/include/asm that
only do:
#include <generated/asm-offsets.h>

I will do so in my patch-set.

Sam
