New Revision: 190081
URL: http://svn.freebsd.org/changeset/base/190081

Log:
  MFC: r186140
  
  Don't try reading the SXP_PINS_DIFF on the 10160 and 12160 SCSI
  controllers. Reading this register, for which there are indications
  that it doesn't really exist, returns 0 on at least some 12160
  and doing so on Sun Fire V880 causes a data access error exception.
  
  Reported and tested by:	Beat Gaetzi
  Approved by:		mjacob
  Obtained from:		OpenBSD (modulo setting isp_lvdmode)
