New Revision: 183733
URL: http://svn.freebsd.org/changeset/base/183733

Log:
  Prefix the static shl function with '__' like its parent function __qdivrem to
  avoid being picked up by the DTrace fbt provider.
  
  This is called by __udivdi3() for doing 64bit division on a 32bit arch and may
  be called from within the dtrace context causing a double fault.
