Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull core irq updates from Thomas Gleixner:
"Updates from the irq departement:

- Update the interrupt spreading code so it handles numa node with
different CPU counts properly.

- A large overhaul of the ARM GiCv3 driver to support new PPI and SPI
ranges.

- Conversion of all alloc_fwnode() users to use physical addresses
instead of virtual addresses so the virtual addresses are not
leaked. The physical address is sufficient to identify the
associated interrupt chip.

- Add support for Marvel MMP3, Amlogic Meson SM1 interrupt chips.

- Enforce interrupt threading at compile time if RT is enabled.

- Small updates and improvements all over the place"

genirq/affinity: Spread vectors on node according to nr_cpu ratio

Now __irq_build_affinity_masks() spreads vectors evenly per node, but there
is a case that not all vectors have been spread when each numa node has a
different number of CPUs which triggers the warning in the spreading code.

Improve the spreading algorithm by

- assigning vectors according to the ratio of the number of CPUs on a node
to the number of remaining CPUs.

- running the assignment from smaller nodes to bigger nodes to guarantee
that every active node gets allocated at least one vector.

This ensures that all vectors are spread out. Asided of that the spread
becomes more fair if the nodes have different number of CPUs.

For example, on the following machine:
CPU(s): 16
On-line CPU(s) list: 0-15
Thread(s) per core: 1
Core(s) per socket: 8
Socket(s): 2
NUMA node(s): 2
...
NUMA node0 CPU(s): 0,1,3,5-9,11,13-15
NUMA node1 CPU(s): 2,4,10,12

When a driver requests to allocate 8 vectors, the following spread results:

irq 31, cpu list 2,4
irq 32, cpu list 10,12
irq 33, cpu list 0-1
irq 34, cpu list 3,5
irq 35, cpu list 6-7
irq 36, cpu list 8-9
irq 37, cpu list 11,13
irq 38, cpu list 14-15

So Node 0 has now 6 and Node 1 has 2 vectors assigned. The original
algorithm assigned 4 vectors on each node which was unfair versus Node 0.

genirq/affinity: Improve __irq_build_affinity_masks()

One invariant of __irq_build_affinity_masks() is that all CPUs in the
specified masks (cpu_mask AND node_to_cpumask for each node) should be
covered during the spread. Even though all requested vectors have been
reached, it's still required to spread vectors among remained CPUs. A
similar policy has been taken in case of 'numvecs <= nodes' already.

So remove the following check inside the loop:

if (done >= numvecs)
break;

Meantime assign at least 1 vector for remaining nodes if 'numvecs' vectors
have been handled already.

Also, if the specified cpumask for one numa node is empty, simply do not
spread vectors on this node.
