Subject: Final per cpu consistency patch for -next or late in 3.19 merge
 period

This is the final patch to remove __get_cpu_var. I checked -next and there
are no remaining uses of __get_cpu_var. So either merge this to -next or
wait until 3.19 late.

However, if we wait till 3.19 then I may have to do another pass if
people add more uses of __get_cpu_var and submit another patch.

Subject: [PATCH] Remove __get_cpu_var and __raw_get_cpu_var macros

No user is left in the kernel source tree. Therefore we can
drop the definitions.

This is the final merge of the transition away from __get_cpu_var.
After this patch the kernel will not build if anyone uses __get_cpu_var.
