It appears that despite its name, the bcm2836_arm_irqchip_ipi_eoi()
callback is an acknowledgement, and not an EOI. This means that
we lose IPIs that are made pending between the handling of the
IPI and the write to LOCAL_MAILBOX0_CLR0. With the right timing,
things fail nicely.

This used to work with handle_percpu_devid_fasteoi_ipi(), which
started by eoi-ing the interrupt. With the standard fasteoi flow,
this doesn't work anymore.

So let's use this callback for what it is, an ack. Your favourite
RPi-2/3 is back up and running.

Since commit 5fe71d27 ("irqchip/gic-v3-its: Tag ITS device as shared if
allocating for a proxy device"), some of the devices are wrongly marked as
"shared" by the ITS driver on systems equipped with the ITS(es). The
problem is that the @info->flags may not be initialized anywhere and we end
up looking at random bits on the stack. That's obviously not good.

We can perform the initialization in the IRQ core layer before calling
msi_domain_prepare_irqs(), which is neat enough.

We have a problem if we use gpio-keys and configure wakeups such that
we only want one edge to wake us up.  AKA:
  wakeup-event-action = <EV_ACT_DEASSERTED>;
  wakeup-source;

Specifically we end up with a phantom interrupt that blocks suspend if
the line was already high and we want wakeups on rising edges (AKA we
want the GPIO to go low and then high again before we wake up).  The
opposite is also problematic.

Specifically, here's what's happening today:
1. Normally, gpio-keys configures to look for both edges.  Due to the
   current workaround introduced in commit c3c0c2e1 ("pinctrl:
   qcom: Handle broken/missing PDC dual edge IRQs on sc7180"), if the
   line was high we'd configure for falling edges.
2. At suspend time, we change to look for rising edges.
3. After qcom_pdc_gic_set_type() runs, we get a phantom interrupt.

We can solve this by just clearing the phantom interrupt.

NOTE: it is possible that this could cause problems for a client with
very specific needs, but there's not much we can do with this
hardware.  As an example, let's say the interrupt signal is currently
high and the client is looking for falling edges.  The client now
changes to look for rising edges.  The client could possibly expect
that if the line has a short pulse low (and back high) that it would
always be detected.  Specifically no matter when the pulse happened,
it should either have tripped the (old) falling edge trigger or the
(new) rising edge trigger.  We will simply not trip it.  We could
narrow down the race a bit by polling our parent before changing
types, but no matter what we do there will still be a period of time
where we can't tell the difference between a real transition (or more
than one transition) and the phantom.

The function accepts an affinity descriptor pointer, which covers all IRQs

The function is devm class as the only current in-tree user will also use

as devm as it can ensure ordering of freeing the irq and disposing of the

- For when the kernel is configured for generic IRQ reservation mode (in

  conflict with managed vs. non-managed interrupt accounting.
- The interrupt is already started, which should not be the case during

- The interrupt is already configured as managed, which means double init

We have two flavours of platform-MSI:

- MSIs generated by devices for themselves (the usual case)

- MSIs generated on behalf of other devices, as the generating
  device is some form of bridge (either a wire-to-MSI bridge,
  or even a non-transparent PCI bridge that repaints the PCI
  requester ID).

In the latter case, the underlying interrupt architecture may need
to track this in order to keep the mapping alive even when no MSI
are currently being generated.

Add a set of flags to the generic msi_alloc_info_t structure, as
well as the MSI_ALLOC_FLAGS_PROXY_DEVICE flag that will get
advertized by the platform-MSI code when allocating an irqdomain
for a device.

ti_sci_intr_irq_domain_free() assumes that out_irq of intr is stored in
data->chip_data and uses it for calling ti_sci irq_free() and then
mark the out_irq as available resource. But ti_sci_intr_irq_domain_alloc()
is storing p_hwirq(parent's hardware irq) which is translated from out_irq.
This is causing resource leakage and eventually out_irq resources might
be exhausted. Fix ti_sci_intr_irq_domain_alloc() by storing the out_irq

handle_percpu_devid_fasteoi_ipi() states:

 * The biggest difference with the IRQ version is that the interrupt is
 * EOIed early, as the IPI could result in a context switch, and we need to
 * make sure the IPI can fire again

All that can actually happen scheduler-wise within the handling of an IPI
is the raising of TIF_NEED_RESCHED (and / or folding thereof into
preempt_count); see scheduler_ipi() or sched_ttwu_pending() for instance.

Said flag / preempt_count is evaluated some time later before returning to
whatever context was interrupted, and this gates a call to
preempt_schedule_irq() (arm64_preempt_schedule_irq() in arm64).

Per the above, SGI's do not need a different handler than PPI's, so make
them use the same (handle_percpu_devid_irq).
