We need to put struct call_single_data in the powerpc thread_struct,
but can't without this.

The thread_struct is in processor.h.  To add a struct call_single_data
to the thread_struct asm/processor.h must include linux/smp.h.  When
linux/smp.h is added to processor.h this creates an include loop via
with list.h via:

  linux/list.h includes: 
    linux/prefetch.h includes:
      asm/processor.h (for powerpc) includes:
        linux/smp.h includes:
          linux/list.h

This loops results in an "incomplete list type" compile when using
struct list_head as used in struct call_single_data.

This patch rearanges some include files to avoid this loop.
