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

Pull alpha architecture fixes from Matt Turner:
 "This contains mostly clean ups and fixes but also an implementation of
  atomic64_dec_if_positive() and a pair of new syscalls"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mattst88/alpha:
  alpha: Use handle_percpu_irq for the timer interrupt
  alpha: Force the user-visible HZ to a constant 1024.
  alpha: Don't if-out dp264_device_interrupt.
  alpha: Use __builtin_alpha_rpcc
  alpha: Fix type compatibility warning for marvel_map_irq
  alpha: Generate dwarf2 unwind info for various kernel entry points.
  alpha: Implement atomic64_dec_if_positive
  alpha: Improve atomic_add_unless
  alpha: Modernize lib/mpi/longlong.h
  alpha: Add kcmp and finit_module syscalls
  alpha: locks: remove unused arch_*_relax operations
  alpha: kernel: typo issue, using '1' instead of '11'
  alpha: kernel: using memcpy() instead of strcpy()
  alpha: Convert print_symbol to %pSR
