Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mattst88/alpha

Pull alpha updates from Matt Turner:
 "Please pull a small collection of patches that I've been neglecting.

  Probably most importantly are the patches that wire up the new
  syscalls needed by udev and the fix to the bootp{,z}file targets"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mattst88/alpha:
  alpha: kernel: osf_sys: Set 'kts.tv_nsec' only when 'tv' has effect
  alpha: Wire up all missing implemented syscalls
  alpha: Fix bootpfile and bootpzfile make targets
  alpha: copy_thread(): rename 'arg' argument to 'kthread_arg'
  alpha: delete non-required instances of <linux/init.h>
  alpha: don't use module_init for non-modular core code
  smp, alpha: kill SMP single function call interrupt
  alpha: Remove #include <uapi/asm/types.h> from <asm/types.h>
  alpha: clean up unnecessary MSI/MSI-X capability find
