New Revision: 210179
URL: http://svn.freebsd.org/changeset/base/210179

Log:
  Add hints for i8254 timer on i386 and amd64. Some people report about
  systems with PnP/ACPI not reporting i8254 timer. In some cases it can be
  fatal, as i8254 can be the only available time counter hardware. From other
  side we are now heavily depend on i8254 timer and till the last time it's
  init/usage was completely hardcoded. So this change just restores previous
  behavior in more regular fashion.
