You should apply ARM:7862/1 before the suspend series and then do not miss:

Think over the __get_cpu_var changes in upstream. I am going to give up too much patchset backporting for this change. and going to backport the this_cpu_ptr to __get_cpu_var by the following patch. If we have to backport __get_cpu_var change later, it is easy to revert this patch. What's your opinions on this?

I merged them both. Thanks!
