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

Pull sparc fixes from David Miller:

 1) Some command cases of semtimedop() not even handled due to miscoded
    comparison on sparc64.  From Rob Gardner.

 2) Due to two bugs, /proc/kcore wan't working properly on sparc.

 3) Make sure fatal traps stop all running cpus, from Dave Kleikamp.

  sparc: Fix /proc/kcore
  sparc: semtimedop() unreachable due to comparison error
  sparc: io_64.h: Replace io function-link macros
