21bbbc50f3 irqchip/gic-v3: Switch high priority PPIs over to handle_percpu_devid_irq()
It so appears that handle_percpu_devid_irq() is extremely similar to
handle_percpu_devid_fasteoi_nmi(), and that the differences do no justify
the horrid machinery in the GICv3 driver to handle the flow handler switch.

Stick with the standard flow handler, even for NMIs.

This callback is optional and the only information that can be reported

structure is designed to be extensible, allowing other potentially relevant
information to be reported in the future.

of asm/percpu.h -- um uses asm-generic/percpu.h directly.

When SMP is enabled, asm-generic/percpu.h will introduce C code
that cannot be assembled. Since asm-generic/percpu.h currently
is not designed for use in assembly, and these assembly files
do not actually need asm/percpu.h on um, let's add the assembly
guard in asm-generic/percpu.h to fix this issue.

1e4ee5135d um: Add initial SMP support
Add initial symmetric multi-processing (SMP) support to UML. With
this support enabled, users can tell UML to start multiple virtual
processors, each represented as a separate host thread.

In UML, kthreads and normal threads (when running in kernel mode)
can be scheduled and executed simultaneously on different virtual
processors. However, the userspace code of normal threads still
runs within their respective single-threaded stubs.

That is, SMP support is currently available both within the kernel
and across different processes, but still remains limited within
threads of the same process in userspace.

ASoC: SDCA: Add early IRQ handling
Some IRQs (FDL) require processing before the primary soundcard is
brought up, as the downloaded files could be firmware required for
operation of the audio functions of the device. Add a new helper
function which registers the required IRQs.

ASoC: SDCA: Add UMP timeout handling for FDL
Several of the UMP transactions in the FDL process should timeout if the
device does not respond within a certain time, add handling into the UMP
helpers and the FDL code to handle this.

ASoC: SDCA: Add completion for FDL start and stop
Add some completions and a helper function to allow other parts of the
system to wait for FDL to complete. The sdca_fdl_sync() function will
wait until it completes a full time out without a new FDL request
happening, this ensures that even parts requiring multiple rounds of FDL
should be fully downloaded before the driver boot continues.

ASoC: SDCA: Add FDL library for XU entities
Some instances of the XU Entity have a need for Files to be downloaded
from the Host. In these XUs, there is one instance of a Host to Device
(Consumer) UMP, identified by the FDL_CurrentOwner Control. FDL Library
introduced here implements the FDL flow triggered by FDL_CurrentOwner
irq, which sends a file from SoundWire File Table (SWFT) or from the
firmware directory in specific cases, to the Device FDL UMP.

Currently only Direct method of FDL is implemented.

even in their Access Mode is Read-Write. Add an explicit list of SDCA

ASoC: SDCA: Rely less on the ASoC component in IRQ handling
In the future some IRQs (mostly the UMPs used during File
DownLoad) will need to run after the device has enumerated on the
bus but before the soundcard is actually constructed. As such
refactor more of the IRQ handling to use raw device and regmap
pointers, rather than accessing things through the component.

ASoC: SDCA: Update externally_requested flag to cover all requests
Currently there is a flag to indicate if an IRQ has been requested by
something outside the SDCA core, such that the core can skip requesting
that IRQ. However, it is simpler and more useful to always store the
allocated IRQ number. This will allow the core to see if the IRQ has
been requested, to perform additional operations on the IRQ, and
request IRQs in multiple phases.

ASoC: SDCA: Add manual PM runtime gets to IRQ handlers
SDCA interrupt handling is a bit odd, the SDCA IRQ registers are
defined on a device level but the handling of the IRQ is at the
Function level. As such the regmap IRQ's PM runtime operations need to
be on the device itself to ensure those registers are available but an
additional runtime get is required for the Function child when the IRQ
is actually handled. Add the required manual PM runtime gets.

regmap: sdw-mbq: Don't assume the regmap device is the SoundWire slave
Currently, the code assumes that the device that registered the
MBQ register map is the actual SoundWire slave device. This works
fine for all current users, however future SDCA devices will
likely be implemented with the SoundWire slave as a parent device
and separate child drivers with regmaps for each audio Function.
Update the regmap_init_sdw_mbq_cfg macro to allow these two
to be specified separately.
