  SVN rev 210314 on 2010-07-20 19:43:25Z by jkim
  
  MFC:    r209965, r209966, r210129, r210137, r210155
  
  - According to ACPICA User Guide and Programmer Reference, the read data
  must be zero extended to fill the 32-bit or 64-bit return value even if
  the bit width of the port or location is less than 32 or 64.
  - Use pmap_mapdev()/pmap_unmapdev() to map device memory instead of using
  AcpiOsMapMemory()/AcpiOsUnmapMemory() (-> pmap_mapbios()/pmap_unmapbios())
  for AcpiOsReadMemory() and AcpiOsWriteMemory().  Although they do not sound
  too obvious, these functions are exclusively used to access memory mapped
  IO in ACPICA.
  - Remove 64-bit access from AcpiOsReadMemory() and AcpiOsWriteMemory().
  These functions do not support 64-bit access.  Likewise, return error when
  64-bit access is requested for PCI configuration space.
  - Clean up some white spaces.
