      Pull "Disintegrate and delete asm/system.h" from David Howells:
       "Here are a bunch of patches to disintegrate asm/system.h into a set of
        separate bits to relieve the problem of circular inclusion
        dependencies.
      
        I've built all the working defconfigs from all the arches that I can
        and made sure that they don't break.
      
        The reason for these patches is that I recently encountered a circular
        dependency problem that came about when I produced some patches to
        optimise get_order() by rewriting it to use ilog2().
      
        This uses bitops - and on the SH arch asm/bitops.h drags in
        asm-generic/get_order.h by a circuituous route involving asm/system.h.
      
        The main difficulty seems to be asm/system.h.  It holds a number of
        low level bits with no/few dependencies that are commonly used (eg.
        memory barriers) and a number of bits with more dependencies that
        aren't used in many places (eg.  switch_to()).
      
        These patches break asm/system.h up into the following core pieces:
      
          (1) asm/barrier.h
      
              Move memory barriers here.  This already done for MIPS and Alpha.
      
          (2) asm/switch_to.h
      
              Move switch_to() and related stuff here.
      
          (3) asm/exec.h
      
              Move arch_align_stack() here.  Other process execution related bits
              could perhaps go here from asm/processor.h.
      
          (4) asm/cmpxchg.h
      
              Move xchg() and cmpxchg() here as they're full word atomic ops and
              frequently used by atomic_xchg() and atomic_cmpxchg().
      
          (5) asm/bug.h
      
              Move die() and related bits.
      
          (6) asm/auxvec.h
      
              Move AT_VECTOR_SIZE_ARCH here.
      
        Other arch headers are created as needed on a per-arch basis."
      
      Fixed up some conflicts from other header file cleanups and moving code
      around that has happened in the meantime, so David's testing is somewhat
      weakened by that.  We'll find out anything that got broken and fix it..
