Author: jkim Date: Fri Jul 16 03:59:50 2010 New Revision: 210155 URL: http://svn.freebsd.org/changeset/base/210155 Log: 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.
