This binding can support Ingenic JZ4725B and JZ4770 SoCs, as they are
compatible with Ingenic JZ4740 battery.
Introduce the following compatible property combinations:
compatible = "ingenic,jz4725b-battery", "ingenic,jz4740-battery",
compatible = "ingenic,jz4770-battery", "ingenic,jz4740-battery"

While chasing in_interrupt() (ab)use in drivers it turned out that the
caif_spi driver has never been in use since the driver was merged 10 years
ago. There never was any matching code which provides a platform device.
The driver has not seen any update (asided of treewide changes and
cleanups) since 8 years and the maintainers vanished from the planet.
So analysing the potential contexts and the (in)correctness of
in_interrupt() usage is just a pointless exercise.
Remove the cruft.

We marked /sys/fs/selinux/checkreqprot as deprecated in Linux v5.7,

PCI devices support two variants of the D3 power state: D3hot (main power
present) D3cold (main power removed). Previously struct pci_dev contained:
unsigned int d3_delay; /* D3->D0 transition time in ms */
unsigned int d3cold_delay; /* D3cold->D0 transition time in ms */
"d3_delay" refers specifically to the D3hot state. Rename it to
"d3hot_delay" to avoid ambiguity and align with the ACPI "_DSM for
Specifying Device Readiness Durations" in the PCI Firmware spec r3.2,
sec 4.6.9.
There is no change to the functionality.

CONFIG_EFI_VARS controls the code that exposes EFI variables via
sysfs entries, which was deprecated before support for non-Intel
architectures was added to EFI. So let's limit its availability
to Intel architectures for the time being, and hopefully remove
it entirely in the not too distant future.
While at it, let's remove the module alias so that the module is
no longer loaded automatically.

This binding is non trivial due to the range of different parts
supported having several subtle quirks. Martin has helped
clarify some of them.
Note, I haven't restricted the amlogic,hhi-sysctrl to only
be present on the relevant parts if nvmem stuff also is, but
it would seem to be rather odd if it were otherwise.
Perhaps we look to make this binding more restrictive at a later date.

KVM_ARM_VCPU_PMU_V3_IRQ returns -EFAULT if get_user() fails when reading

KVM_ARM_VCPU_PMU_V3_INIT returns the error value from kvm_vgic_set_owner().
kvm_arm_pmu_v3_init() checks that the vgic has been initialized and the

There are behavioural requirements on the seq_file next() function in
terms of how it updates *pos at end-of-file, and these are now enforced
by a warning.
I was recently attempting to justify the reason this was needed, and
couldn't remember the details, and didn't find them in the
documentation.
So I re-read the code until I understood it again, and updated the
documentation to match.
I also enhanced the text about SEQ_START_TOKEN as it seemed potentially
misleading.

Initial driver for PMU event counting on the Arm CMN-600 interconnect.
CMN sports an obnoxiously complex distributed PMU system as part of
its debug and trace features, which can do all manner of things like
sampling, cross-triggering and generating CoreSight trace. This driver
covers the PMU functionality, plus the relevant aspects of watchpoints
for simply counting matching flits.

a fallback to benefit from its automatic probing of child nodes.
However, simple-bus also comes with some constraints, like having the ranges,
our case.
Let's switch to simple-mfd that provides the same probing logic without
those constraints.
