Keeping the IRQ chip definition static shares it with multiple instances
of the GPIO chip in the system. This is bad and now we get this warning
from GPIO library:
"detected irqchip that is shared with multiple gpiochips: please fix the driver."
Hence, move the IRQ chip definition from being driver static into the struct
intel_pinctrl. So a unique IRQ chip is used for each GPIO chip instance.
This patch is heavily based on the attachment to the bug by Christoph Marz.

Commit 03c4749dd6 ("gpio / ACPI: Drop unnecessary ACPI GPIO to Linux
GPIO translation") has made the cherryview gpio numbers sparse, to get
a 1:1 mapping between ACPI pin numbers and gpio numbers in Linux.
This has greatly simplified things, but the code setting the
irq_valid_mask was not updated for this, so the valid mask is still in
the old "compressed" numbering with the gaps in the pin numbers skipped,
which is wrong as irq_valid_mask needs to be expressed in gpio numbers.
This results in the following error on devices using pin 24 (0x0018) on
the north GPIO controller as an ACPI event source:
[ 0.422452] cherryview-pinctrl INT33FF:01: Failed to translate GPIO to IRQ
This has been reported (by email) to be happening on a Caterpillar CAT T20
tablet and I've reproduced this myself on a Medion Akoya e2215t 2-in-1.
This commit uses the pin number instead of the compressed index into
community->pins to clear the correct bits in irq_valid_mask for GPIOs
using GPEs for interrupts, fixing these errors and in case of the
Medion Akoya e2215t also fixing the LID switch not working.

When consumer requests a pin, in order to be on the safest side,
we switch it first to GPIO mode followed by immediate transition
to the input state. Due to posted writes it's luckily to be a single
I/O transaction.
However, if firmware or boot loader already configures the pin
to the GPIO mode, user expects no glitches for the requested pin.
We may check if the pin is pre-configured and leave it as is
till the actual consumer toggles its state to avoid glitches.

As part of the uapi we export a lot of PT_xx defines for each register
in struct pt_regs. These are expressed as an index from gpr[0], in
units of unsigned long.
Currently there's nothing tying the values of those defines to the
actual layout of the struct.
But we *don't* want to change the uapi defines to derive the PT_xx
values based on the layout of the struct, those values are ABI and
must never change.
Instead we want to do the reverse, make sure that the layout of the
struct never changes vs the PT_xx defines. So add build time checks of
that.
This probably seems paranoid, but at least once in the past someone
has sent a patch that would have broken the ABI if it hadn't been
spotted. Although it probably would have been detected via testing,
it's preferable to just quash any issues at the source.

When gfs2 was converted to use fs_context, the initialisation of the
mount args structure to the currently active args was lost with the
removal of gfs2_remount_fs(), so the checks of the new args on remount
became checks against the default values instead of the current ones.
This caused unexpected remount behaviour and test failures (xfstests
generic/294, generic/306 and generic/452).
Reinstate the args initialisation, this time in gfs2_init_fs_context()
and conditional upon fc->purpose, as that's the only time we get control
before the mount args are parsed in the remount process.

Non-Transparent Bridge (NTB) devices (among others) may have many DMA
aliases seeing the hardware will send requests with different device ids
depending on their origin across the bridged hardware.
See commit ad281ecf1c ("PCI: Add DMA alias quirk for Microsemi Switchtec
NTB") for more information on this.
The AMD IOMMU IRQ remapping functionality ignores all PCI aliases for
IRQs so if devices send an interrupt from one of their aliases they
will be blocked on AMD hardware with the IOMMU enabled.
To fix this, ensure IRQ remapping is enabled for all aliases with
MSI interrupts.
This is analogous to the functionality added to the Intel IRQ remapping
code in commit 3f0c625c6a ("iommu/vt-d: Allow interrupts from the entire
bus for aliased devices")
