When allocating a range of LPIs for a Multi-MSI capable device,
this allocation extended to the closest power of 2.
But on the release path, the interrupts are released one by
one. This results in not releasing the "extra" range, leaking
the its_device. Trying to reprobe the device will then fail.
Fix it by releasing the LPIs the same way we allocate them.

Recently device pass-through stops working for Linux VM running on Hyper-V.
git-bisect shows the regression is caused by the recent commit
467a3bb974 ("PCI: hv: Allocate a named fwnode ..."), but the root cause
is that the commit d59f6617ee forgets to set the domain->fwnode for
IRQCHIP_FWNODE_NAMED*, and as a result:
1. The domain->fwnode remains to be NULL.
2. irq_find_matching_fwspec() returns NULL since "h->fwnode == fwnode" is
false, and pci_set_bus_msi_domain() sets the Hyper-V PCI root bus's
msi_domain to NULL.
3. When the device is added onto the root bus, the device's dev->msi_domain
is set to NULL in pci_set_msi_domain().
4. When a device driver tries to enable MSI-X, pci_msi_setup_msi_irqs()
calls arch_setup_msi_irqs(), which uses the native MSI chip (i.e.
arch/x86/kernel/apic/msi.c: pci_msi_controller) to set up the irqs, but
actually pci_msi_setup_msi_irqs() is supposed to call
msi_domain_alloc_irqs() with the hbus->irq_domain, which is created in
hv_pcie_init_irq_domain() and is associated with the Hyper-V chip
hv_msi_irq_chip. Consequently, the irq line is not properly set up, and
the device driver can not receive any interrupt.

The "regs" property of the "mrvl,mmp2-mux-intc" devices are silly. They
are offsets from intc's base, not addresses on the parent bus. At this
point it probably can't be fixed.
On an OLPC XO-1.75 machine, the muxes are children of the intc, not the
axi bus, and thus of_address_to_resource() won't work. We should treat
the values as mere integers as opposed to bus addresses.

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.

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.

We're about to change all that, with new ranges such as EPPI and ESPI
interleaved in the middle of the no-irq-land between the "special IDs"
and the LPI range. Boo.

gic_configure_irq is currently passed the (re)distributor address,

address of the configuration register for the considered interrupt.

A few style fixes for some SPDX comments, added an SPDX tag for one

issues (they are comment changes only, so that's to be expected...)"

Here are some small char and misc driver fixes for 5.3-rc5.
These are two different subsystems needing some fixes, the habanalabs
driver which is has some more big endian fixes for problems found. The
other are some small soundwire fixes, including some Kconfig
dependencies needed to resolve reported build errors.
All of these have been in linux-next this week with no reported issues.

Syzbot has been on a tear recently now that it has some good USB
debugging hooks integrated, so there's a number of fixes in here found
by those tools for some _very_ old bugs. Also a handful of gadget
driver fixes for reported issues, some hopefully-final dma fixes for
host controller drivers, and some new USB serial gadget driver ids.
All of these have been in linux-next this week with no reported issues
