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

Pull sparc fixes from David Miller:

 1) System call tracing doesn't handle register contents properly across
    the trace.  From Mike Frysinger.

 2) Hook up copy_file_range

 3) Build fix for 32-bit with newer tools.

 4) New sun4v watchdog driver, from Wim Coekaerts.

 5) Set context system call has to allow for servicable faults when we
    flush the register windows to memory
