Hi Arnd, Olof,

The Keystone QMSS driver is pretty damaged, in the sense that it
does things like this:

irq_set_affinity_hint(irq, to_cpumask(&cpu_map));

where cpu_map is a local variable. As we leave the function, this
will point to nowhere-land, and things will end-up badly.

Instead, let's use a proper cpumask that gets allocated, giving
the driver a chance to actually work with things like irqbalance
as well as have a hypothetical 64bit future.
