Saurabh added the ARCH variable. He's CCed. BTW I think your patch can be simplified by using ARCH ?= $(shell uname -m 2>/dev/null) instead of the ifeq test in your patch. I don't think that's correct. ARCH will be set to the correct value by Kbuild. Saurabh and Adrian, can you test the following patch? Thanks, Wei.
