New Revision: 245120
URL: http://svnweb.freebsd.org/changeset/base/245120

Log:
  Release version check for erratum 727915 workaround in
  l2_wbinv_range function implementation causes function
  fail to flush caches for chip with RTL number 0x7. I failed
  to find official PL310 revision with this RTL number
  so further research on this matter required.
