86e62b9336 ARM: SMP: remove smp_mpidr.h
With "ARM: CPU hotplug: remove bug checks in platform_cpu_die()", we
now do not use hard_smp_processor_id(), we no longer need to read the
hardware processor ID.  Remove the include providing this function.

ad3b6993b9 ARM: SMP: pass an ipi number to smp_cross_call()
This allows us to use smp_cross_call() to trigger a number of different
software generated interrupts, rather than combining them all on one
SGI.  Recover the SGI number via do_IPI.

78d236c2b3 [ARM] realview: remove useless smp_cross_call_done()
smp_cross_call_done() is a no-op for MPCore, and since it's only
used by platform code, there's no point in having it unless it's
doing something.

826681043d [ARM] smp: fix cpumask usage in ARM SMP code
The ARM SMP code wasn't properly updated for the cpumask changes, which
results in smp_timer_broadcast() broadcasting ticks to non-online CPUs.

This just leaves include/asm-arm/plat-* to deal with.
