Pull tilepro fix from Chris Metcalf:
 "This change allows the older tilepro architecture to be correctly
  built by newer gccs, despite a change that caused gcc to start trying
  to use an out-of-line implementation for __builtin_ffsll().

  This should be inline again starting with gcc 4.7.4 and 4.8.2 or so,
  but meanwhile this change keeps things from breaking, with the only
  cost being a few bytes of code in the kernel to provide __ffsdi2 even
  for compilers that do inline it"

* 'stable' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile:
  tilepro: work around module link error with gcc 4.7

+       is an error action.  In that case, don't check for expected

+     - The only way there can be no lookahead present (in yychar) is if
+       this state is a consistent state with a default action.  Thus,
+       detecting the absence of a lookahead is sufficient to determine
+       that there is no unexpected or expected token to report.  In that
+       case, just report a simple "syntax error".
+     - Don't assume there isn't a lookahead just because this state is a
+       consistent state with a default action.  There might have been a
+       previous inconsistent state, consistent state with a non-default
+       action, or user semantic action that manipulated yychar.
+     - Of course, the expected token list depends on states to have
+       correct lookahead information, and it depends on the parser not
+       to perform extra reductions after fetching a lookahead from the
+       scanner and before detecting a syntax error.  Thus, state merging
+       (from LALR or IELR) and default reductions corrupt the expected
+       token list.  However, the list is correct for canonical LR with
+       one exception: it will still contain any token that will not be
+       accepted due to an error action in a later state.
