eventfd: simplify eventfd_signal()
Ever since the eventfd type was introduced back in 2007 in commit
e1ad7468c7 ("signal/timer/event: eventfd core") the eventfd_signal()
function only ever passed 1 as a value for @n. There's no point in
keeping that additional argument.

This series follows through with the cleanup of redundant code now that PCI
Advanced Error Reporting (AER) enablement has been moved into the kernel's
PCI core.
During upstream v6.0, commit f26e58bf6f54 "PCI/AER: Enable error reporting
when AER is native" - which came from upstream merge commit 5a20930f27c4
"Merge branch 'pci/err'" - PCI Advanced Error Reporting (AER) was
refactored. The refactoring consisted of moving the enablement of error
reporting into the PCI core as opposed to being the responsibility of each
individual device driver. With this commit the PCI core now sets the Device
Control bits that enable error reporting for PCIe devices.
Upstream commit f26e58bf6f54 was back-ported into RHEL in an earlier release
via commit e416587df70c.
With enablement now taking place within the PCI core, the next step was to
remove all the now redundant enablement and disablement calls from each of
the individual device drivers. This took place from v6.3 through v6.5 and
is the bulk of this series content: removing all occurrances of
'pci_enable_pcie_error_reporting()' and 'pci_disable_pcie_error_reporting()'
calls from device drivers.
Finally, with AER enablement and disablement removed from all device
drivers, that code could now be completely isolated (i.e., static) to the
PCI subsystem's AER related file. This took place during v6.6 via the
following commits:
3e2a87a0cffe Merge branch 'pci/aer'
7ec4b34be423 PCI/AER: Unexport pci_enable_pcie_error_reporting()
69b264df8a41 PCI/AER: Drop unused pci_disable_pcie_error_reporting()
All patches in the series back-ported cleanly.

fpga: dfl-pci: Drop redundant pci_enable_pcie_error_reporting()
pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages. Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration, so the
driver doesn't need to do it itself.
Remove the redundant pci_enable_pcie_error_reporting() call from the
driver. Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.
Note that this only controls ERR_* Messages from the device. An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

Tested: This is one of a series of patch sets to enable Arm SystemReady IR
support in the kernel for NXP i.MX8 platforms. At this stage, this
has been tested by ensuring we can survive the CI/CD loop -- i.e.,
that we have not broken anything else, and a simple boot test. When
sufficient drivers have been brought in for i.MX8M, we will be able
to run further tests.
Conflicts:
drivers/dma/idxd/sysfs.c -- there is no driver remove function
to be modified so ignored this portion of the patch.
drivers/vfio/mdev/mdev_driver.c -- slightly different context
than expected but again this is a simple type change for
a function causing a simple "return" to also be removed.
drivers/net/netdevsim/bus.c -- similar to mdev_driver.c, there
is a different overall context, but this change is only a simple
function return type change (int to void).

bus: Make remove callback return void
The driver core ignores the return value of this callback because there
is only little it can do when a device disappears.
This is the final bit of a long lasting cleanup quest where several
buses were converted to also return void from their remove callback.
Additionally some resource leaks were fixed that were caused by drivers
returning an error code in the expectation that the driver won't go
away.
With struct bus_type::remove returning void it's prevented that newly
implemented buses return an ignored error code and so don't anticipate
wrong expectations for driver authors.

The performance reporting driver added cpu hotplug
feature but it didn't add pmu migration call in cpu
offline function.
This can create an issue incase the current designated
cpu being used to collect fme pmu data got offline,
as based on current code we are not migrating fme pmu to
new target cpu. Because of that perf will still try to
fetch data from that offline cpu and hence we will not
get counter data.
Patch fixed this issue by adding pmu_migrate_context call
in fme_perf_offline_cpu function.

Agilex, N5X and Stratix 10 share all quite similar arm64 hard cores and
SoC-part. Up to a point that N5X uses the same DTSI as Agilex. From
the Linux kernel point of view these are flavors of the same
architecture so there is no need for three top-level arm64
architectures. Simplify this by merging all three architectures into
ARCH_INTEL_SOCFPGA and dropping the other ARCH* arm64 Kconfig entries.
The side effect is that the INTEL_STRATIX10_SERVICE will now be
available for both 32-bit and 64-bit Intel SoCFPGA, even though it is

on a Reconfigurable Partition when it is undergoing dynamic reconfiguration
and there by preventing system deadlock that may occur if AXI transactions
are interrupted during reconfiguration.
PR-Decoupler and AXI shutdown manager are completely different IPs.
But both the IP registers are compatible and also both belong to the
same sub-system (fpga-bridge).So using same driver for both IP's.

This is the first set of changes for the FPGA Manager 5.12-rc1
mergewindow.
DFL:
- Minor cleanup, constifying a static attribute group
Core:
- Minor cleanup, using DEFINE_SPINLOCK over open coding it
All patches have been reviewed on the mailing list, and have been in the
last linux-next releases (as part of my for-next branch) without issues.

fpga: dfl: fme: Constify static attribute_group structs
fpga: Use DEFINE_SPINLOCK() for spinlock
The only usage of these is to put their addresses in arrays of pointers
to const attribute_groups. Make them const to allow the compiler to put
them in read-only memory.

This patch adds support for the Nios handshake private feature on Intel
PAC (Programmable Acceleration Card) N3000.
The Nios is the embedded processor on the FPGA card. This private feature
provides a handshake interface to FPGA Nios firmware, which receives
retimer configuration command from host and executes via an internal SPI
master (spi-altera). When Nios finishes the configuration, host takes over
the ownership of the SPI master to control an Intel MAX10 BMC (Board
Management Controller) Chip on the SPI bus.
For Nios firmware handshake part, this driver requests the retimer
configuration for Nios firmware on probe, and adds some sysfs nodes for
user to query the onboard retimer's working mode and Nios firmware
version.
For SPI part, this driver adds a spi-altera platform device as well as
the MAX10 BMC spi slave info. A spi-altera driver will be matched to
handle the following SPI work.

Now the dfl drivers could be made as independent modules and put in
different folders according to their functionalities. In order for
scattered dfl device drivers to include dfl bus APIs, move the
dfl bus APIs to a new header file in the public folder.

The value of the field dfl_device.type comes from the 12 bits register
field DFH_ID according to DFL spec. So this patch changes the definition
of the type field to u16.
Also it is not necessary to illustrate the valid bits of the type field
in comments. Instead we should explicitly define the possible values in
the enumeration type for it, because they are shared by hardware spec.
We should not let the compiler decide these values.
Similar changes are also applied to dfl_device.feature_id.
This patch also fixed the MODALIAS format according to the changes
above.

Because dfl.c uses the 'devm_ioremap', 'devm_iounmap',
'devm_ioremap_resource', and 'devm_platform_ioremap_resource'
functions, it should depend on HAS_IOMEM.
This fixes make allyesconfig under UML (ARCH=um), which doesn't provide
HAS_IOMEM.

A new bus type "dfl" is introduced for private features which are not
initialized by DFL feature drivers (dfl-fme & dfl-afu drivers). So these
private features could be handled by separate driver modules.
DFL feature drivers (dfl-fme, dfl-port) will create DFL devices on
enumeration. DFL drivers could be registered on this bus to match these
DFL devices. They are matched by dfl type & feature_id.
