New Revision: 184547
URL: http://svn.freebsd.org/changeset/base/184547

Log:
  We've been lax about matching END() macros in asm code for some time.  This
  is used to set the ELF size attribute for functions.  It isn't normally
  critical but some things can make use of it (gdb for stack traces).
  Valgrind needs it so I'm adding it in.  The problem is present on all
  branches and on both i386 and amd64.
