Several sparc64 bug fixes here:

1) Make the user copy routines on sparc64 return a properly accurate
   residual length when an exception occurs.

2) We can get enormous kernel TLB range flush requests from vmalloc
   unmaps, so handle these more gracefully by doing full flushes
   instead of going page-by-page.

3) Cope properly with negative branch offsets in sparc jump-label
   support, from James Clarke.

4) Some old-style decl GCC warning fixups from Tobias Klauser.

Please pull, thanks a lot!
