Author: dim Date: Fri Feb 28 20:22:48 2014 New Revision: 262620 URL: http://svnweb.freebsd.org/changeset/base/262620 Log: MFC r262471: In sys/sparc64/sparc64/spitfire.c, prevent signed shift overflow by casting to the appropriate type. (Note this fix cannot be done in sys/sparc64/sparc64/spitfire.c, since that file is also included by assembly source files.)
