Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc 

Pull sparc fixes from David Miller:
 "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"

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
  sparc64: Handle extremely large kernel TLB range flushes more gracefully.
  sparc64: Fix illegal relative branches in hypervisor patched TLB cross-call code.
  sparc64: Fix instruction count in comment for __hypervisor_flush_tlb_pending.
  sparc64: Handle extremely large kernel TSB range flushes sanely.
  sparc: Handle negative offsets in arch_jump_label_transform
  sparc64: Fix illegal relative branches in hypervisor patched TLB code.
  sparc64: Delete now unused user copy fixup functions.
  sparc64: Delete now unused user copy assembler helpers.
  sparc64: Convert U3copy_{from,to}_user to accurate exception reporting.
  sparc64: Convert NG2copy_{from,to}_user to accurate exception reporting.
  sparc64: Convert NGcopy_{from,to}_user to accurate exception reporting.
  sparc64: Convert NG4copy_{from,to}_user to accurate exception reporting.
  sparc64: Convert U1copy_{from,to}_user to accurate exception reporting.
  sparc64: Convert GENcopy_{from,to}_user to accurate exception reporting.
  sparc64: Convert copy_in_user to accurate exception reporting.
  sparc64: Prepare to move to more saner user copy exception handling.
  sparc64: Delete __ret_efault.
  sparc32: Fix old style declaration GCC warnings
  sparc64: Fix old style declaration GCC warnings
  sparc64: Setup a scheduling domain for highest level cache.
