Tune the PWM to solve screen flashing issue and high frequency noise.
While at it, the comment for the PWM settings incorrectly said we were
using a 5kHz duty cycle. It should have said "period", not "duty cycle".
Correct this while updating the values.

Nodes like pwrkey, resin, iadc, adc-tm, temp-alarm which are the grand
children of spmi_bus node represent the interrupt generating devices but
don't have "interrupt-parent" property.
As per the devicetree spec v0.3, section 2.4:
"The physical wiring of an interrupt source to an interrupt controller is
represented in the devicetree with the interrupt-parent property. Nodes
that represent interrupt-generating devices contain an interrupt-parent
property which has a phandle value that points to the device to which the
device’s interrupts are routed, typically an interrupt controller. If an
interrupt-generating device does not have an interrupt-parent property,
its interrupt parent is assumed to be its devicetree parent."
This clearly says that if the "interrupt-parent" property is absent, then
the immediate devicetree parent will be assumed as the interrupt parent.
But the immediate parents of these nodes are not interrupt controllers
themselves.
This may lead to failure while wiring the interrupt for these nodes by an
operating system. But a few operating systems like Linux, workaround this
issue by walking up the parent nodes until it finds the "interrupt-cells"
property. Then the node that has the "interrupt-cells" property will be
used as the interrupt parent.
But this workaround is not as per the DT spec and is not being implemented
by other operating systems such as OpenBSD.
Hence, fix this issue by adding the "interrupts-extended" property that
explicitly specifies the spmi_bus node as the interrupt parent. Note that
the "interrupts-extended" property is chosen over "interrupt-parent" as it
allows specifying both interrupt parent phandle and interrupt specifiers in
a single property.

Provide a slimline configuration intended to be booted on virtual
machines, with the goal of providing a light configuration which will
boot on and enable features available in mach-virt. This is defined in
terms of the standard defconfig, with an additional virt.config fragment
which disables options unneeded in a virtual configuration.
As a first step we just disable all the ARCH_ configuration options,
disabling the build of all the SoC specific drivers. This results in a
kernel that builds about 25% faster in my testing, if this approach
works for people we can add further options.

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into timers/core
Pull clocksource watchdog changes from Paul McKenney:
o Improvements to clocksource-watchdog console messages.
o Loosening of the clocksource-watchdog skew criteria to match
those of NTP (500 parts per million, relaxed from 400 parts
per million). If it is good enough for NTP, it is good enough
for the clocksource watchdog.
o Suspend clocksource-watchdog checking temporarily when high
memory latencies are detected. This avoids the false-positive
clock-skew events that have been seen on production systems
running memory-intensive workloads.
o On systems where the TSC is deemed trustworthy, use it as the
watchdog timesource, but only when specifically requested using
the tsc=watchdog kernel boot parameter. This permits clock-skew
events to be detected, but avoids forcing workloads to use the
slow HPET and ACPI PM timers. These last two timers are slow
enough to cause systems to be needlessly marked bad on the one
hand, and real skew does sometimes happen on production systems
running production workloads on the other. And sometimes it is
the fault of the TSC, or at least of the firmware that told the
kernel to program the TSC with the wrong frequency.
o Add a tsc=revalidate kernel boot parameter to allow the kernel
to diagnose cases where the TSC hardware works fine, but was told
by firmware to tick at the wrong frequency. Such cases are rare,
but they really have happened on production systems.

Having a clocksource_arch_init() callback always sets vdso_clock_mode to
VDSO_CLOCKMODE_ARCHTIMER if GENERIC_GETTIMEOFDAY is enabled, this is
required for the riscv-timer.
This works for platforms where just riscv-timer clocksource is present.
On platforms where other clock sources are available we want them to
register with vdso_clock_mode set to VDSO_CLOCKMODE_NONE.
On the Renesas RZ/Five SoC OSTM block can be used as clocksource [0], to
avoid multiple clock sources being registered as VDSO_CLOCKMODE_ARCHTIMER
move setting of vdso_clock_mode in the riscv-timer driver instead of doing
this in clocksource_arch_init() callback as done similarly for ARM/64
architecture.

Similarly to commit 022eb8ae8b5e ("ARM: 8938/1: kernel: initialize
broadcast hrtimer based clock event device"), RISC-V needs to initiate
hrtimer based broadcast clock event device before C3STOP can be used.
Otherwise, the introduction of C3STOP for the RISC-V arch timer in
commit 232ccac1bd9b ("clocksource/drivers/riscv: Events are stopped
during CPU suspend") leaves us without any broadcast timer registered.
This prevents the kernel from entering oneshot mode, which breaks timer
behaviour, for example clock_nanosleep().
A test app that sleeps each cpu for 6, 5, 4, 3 ms respectively, HZ=250
& C3STOP enabled, the sleep times are rounded up to the next jiffy:
== CPU: 1 == == CPU: 2 == == CPU: 3 == == CPU: 4 ==

The uncore subsystem for Meteor Lake is similar to the previous Alder
Lake. The main difference is that MTL provides PMU support for different
tiles, while ADL only provides PMU support for the whole package. On
ADL, there are CBOX, ARB, and clockbox uncore PMON units. On MTL, they
are split into CBOX/HAC_CBOX, ARB/HAC_ARB, and cncu/sncu which provides
a fixed counter for clockticks. Also, new MSR addresses are introduced
on MTL.
The IMC uncore PMON is the same as Alder Lake. Add new PCIIDs of IMC for
Meteor Lake.

The time order is incorrect when the TSC in a PEBS record is used.
$perf record -e cycles:upp dd if=/dev/zero of=/dev/null
count=10000
$ perf script --show-task-events
perf-exec 0 0.000000: PERF_RECORD_COMM: perf-exec:915/915
dd 915 106.479872: PERF_RECORD_COMM exec: dd:915/915
dd 915 106.483270: PERF_RECORD_EXIT(915:915):(914:914)
dd 915 106.512429: 1 cycles:upp:
ffffffff96c011b7 [unknown] ([unknown])
... ...
The perf time is from sched_clock_cpu(). The current PEBS code
unconditionally convert the TSC to native_sched_clock(). There is a
shift between the two clocks. If the TSC is stable, the shift is
consistent, __sched_clock_offset. If the TSC is unstable, the shift has
to be calculated at runtime.
This patch doesn't support the conversion when the TSC is unstable. The
TSC unstable case is a corner case and very unlikely to happen. If it
happens, the TSC in a PEBS record will be dropped and fall back to
perf_event_clock().

By default, KVM/SVM will intercept attempts by the guest to transition
out of C0. However, the KVM_CAP_X86_DISABLE_EXITS capability can be used
by a VMM to change this behavior. To mitigate the cross-thread return
address predictions bug (X86_BUG_SMT_RSB), a VMM must not be allowed to
override the default behavior to intercept C0 transitions.
Use a module parameter to control the mitigation on processors that are
vulnerable to X86_BUG_SMT_RSB. If the processor is vulnerable to the
X86_BUG_SMT_RSB bug and the module parameter is set to mitigate the bug,
KVM will not allow the disabling of the HLT, MWAIT and CSTATE exits.

Certain AMD processors are vulnerable to a cross-thread return address
predictions bug. When running in SMT mode and one of the sibling threads
transitions out of C0 state, the other sibling thread could use return
target predictions from the sibling thread that transitioned out of C0.
The Spectre v2 mitigations cover the Linux kernel, as it fills the RSB
when context switching to the idle thread. However, KVM allows a VMM to
prevent exiting guest mode when transitioning out of C0. A guest could
act maliciously in this situation, so create a new x86 BUG that can be
used to detect if the processor is vulnerable.

In commit 588a513d3425 ("arm64: Fix race condition on PG_dcache_clean
in __sync_icache_dcache()"), we found RISC-V has the same issue as the
previous arm64. The previous implementation didn't guarantee the correct
sequence of operations, which means flush_icache_all() hasn't been
called when the PG_dcache_clean was set. That would cause a risk of page
synchronization.
