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
