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

Pull sparc updates from David Miller:
 "Nothing much this merge window for sparc.

  1) Fix FPU state management in sparc32, from Tkhai Kirill.

  2) More sparc32 mm layer code cleanups, largely more side effects of
     the sun4c support removal in the 3.5 From Sam Ravnborg.

  3) Remove unused code in sparc64, from Bjorn Helgaas and Kirill Tkhai.

  4) Some declaration and comment tidies in PROM support code, from
     Geert Uytterhoeven."
