svn commit: r190602 - head/sys/arm/arm

[Olivier Houchard]

Author: cognet
Date: Tue Mar 31 23:06:20 2009
New Revision: 190602
URL: http://svn.freebsd.org/changeset/base/190602

Log:
  Use Oxf0000000 instead of 0xff000000 to guess the physical address, relative
  to the virtual one. I may had a reason at some point to use the later, but
  can't remember which, and it can leads to issues.
