Author: thompsa Date: Wed Oct 29 21:43:14 2008 New Revision: 184457 URL: http://svn.freebsd.org/changeset/base/184457 Log: MFC r183733 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.
