smp.h: move !SMP version of on_each_cpu() out-of-line
All of the other non-trivial !SMP versions of functions in smp.h are out-of-line in up.c. Move on_each_cpu() there as well. This allows us to get rid of the #include <linux/irqflags.h>. The drawback is that this makes both the x86_64 and i386 defconfig !SMP kernels about 200 bytes larger each.
