Ryzen 7000 (Raphael) introduced AMDI0008 for _HID.  This ID was added
in commit ed470feb ("ACPI: PM: s2idle: Add support for upcoming AMD
uPEP HID AMDI008"), but then removed in favor of aligning all new IDs
to Rembrandt support in commit fd894f05 ("ACPI: x86: s2idle: If a

Unfortunately there was a mistake in commit 100a5737 ("ACPI: x86:

lead to a NULL pointer dereference accessing `dev_id->driver_data` in

The PCI device returned by acpi_get_pci_dev() needs to be registered,
so if it corresponds to an ACPI device object, the struct acpi_device
representing that object must be registered too and, moreover, it
should be the ACPI companion of the given PCI device.  Thus it should
be sufficient to look for it in the ACPI device object's list of
physical nodes associated with it.

Modify the code accordingly.

The previous patch triggered a build failure for the debian kernel,
which has CONFIG_64BIT enabled, uses the CROSS_COMPILER environment
variable and uses ARCH=parisc to configure the kernel for 64-bit
support.

This patch weakens the previous patch while keeping the recommended way
to configure the kernel with:
    ARCH=parisc     -> build 32-bit kernel
    ARCH=parisc64   -> build 64-bit kernel
while adding the possibility for debian to configure a 64-bit kernel
even if ARCH=parisc is set (PA8X00 CPU has to be selected and
CONFIG_64BIT needs to be enabled).

The downside of this patch is, that we now have a small window open
again where people may get it wrong: if they enable CONFIG_64BIT and try
to compile with a 32-bit compiler.

sure the sdma doorbell range is properly initialized.

There is a comment about the way doorbells on gfx9 work that
requires that they are initialized for other IPs before GFX
is initialized.  However, the statement says that it applies to
multimedia as well, but the VCN code currently initializes
doorbells after GFX and there are no known issues there.  In my
testing at least I don't see any problems on SDMA.

This is a prerequisite for fixing the Unsupported Request error
reported through AER during driver load.

The error was unnoticed before and got visible because of the commit
referenced below. This doesn't fix anything in the commit below, rather
fixes the issue in amdgpu exposed by the commit. The reference is only
to associate this commit with below one so that both go together.

This mirrors what we do for other asics and this way we are
sure the ih doorbell range is properly initialized.

There is a comment about the way doorbells on gfx9 work that
requires that they are initialized for other IPs before GFX
is initialized.  In this case IH is initialized before GFX,
so there should be no issue.

When an external device generated a level based interrupt then the
interrupt controller could miss the interrupt. The reason is that the
interrupt controller can detect only link changes.

In the following example, if there is a PHY that generates an interrupt
then the following would happen. The GPIO detected that the interrupt
line changed, and then the 'ocelot_irq_handler' was called. Here it
detects which GPIO line saw the change and for that will call the
following:
1. irq_mask
2. phy interrupt routine
3. irq_eoi
4. irq_unmask

And this works fine for simple cases, but if the PHY generates many
interrupts, for example when doing PTP timestamping, then the following
could happen. Again the function 'ocelot_irq_handler' will be called
and then from here the following could happen:
1. irq_mask
2. phy interrupt routine
3. irq_eoi
4. irq_unmask

Right before step 3(irq_eoi), the PHY will generate another interrupt.
Now the interrupt controller will acknowledge the change in the
interrupt line. So we miss the interrupt.

A solution will be to use 'handle_level_irq' instead of
'handle_fasteoi_irq', because for this will change routine order of
handling the interrupt.
1. irq_mask
2. irq_ack
3. phy interrupt routine
4. irq_unmask

And now if the PHY will generate a new interrupt before irq_unmask, the
interrupt controller will detect this because it already acknowledge the
change in interrupt line at step 2(irq_ack).

But this is not the full solution because there is another issue. In
case there are 2 PHYs that share the interrupt line. For example phy1
generates an interrupt, then the following can happen:
1.irq_mask
2.irq_ack
3.phy0 interrupt routine
4.phy1 interrupt routine
5.irq_unmask

In case phy0 will generate an interrupt while clearing the interrupt
source in phy1, then the interrupt line will be kept down by phy0. So
the interrupt controller will not see any changes in the interrupt line.
The solution here is to update 'irq_unmask' such that it can detect if
the interrupt line is still active or not. And if it is active then call
again the procedure to clear the interrupts. But we don't want to do it
every time, only if we know that the interrupt controller has not seen
already that the interrupt line has changed.

While at this, add support also for IRQ_TYPE_LEVEL_LOW.
