      [PATCH] Introduce __iowrite32_copy · c27a0d75
      Bryan O'Sullivan authored
      This arch-independent routine copies data to a memory-mapped I/O region,
      using 32-bit accesses.  The naming is double-underscored to make it clear
      that it does not guarantee write ordering, nor does it perform a memory
      barrier afterwards; the kernel doc also explicitly states this.  This style
      of access is required by some devices.
      
      This change also introduces include/linux/io.h, at Andrew's suggestion.  It
      only has one occupant at the moment, but is a logical destination for
      oft-replicated contents of include/asm-*/{io,iomap}.h to migrate to.
