when disable CONFIG_SMP, we can't build success because of error: implicit declaration of function ‘per_cpu_offset’ per_cpu_offset is available only if CONFIG_SMP is enable.

You should apply commit b57fc9e80692043e2a3a74e1d2c047eb700dcd0c in the mainline instead, that's already been fixed.

I'm sorry. By the way, can you tell me which branch should I track? On Fri, May 02, 2014 at 09:39:43AM +0100, Lorenzo Pieralisi wrote:
