The i.MX8M/Mini/Nano/Plus variant of the SAI IP has control registers
shifted by +8 bytes and requires additional bus clock. Document support
for the i.MX8M variant of the IP with this register shift and additional
clock. Update the description slightly.

Pull round_rate refactoring from Brian Masney:
Now that all of the dependencies across the tree have been merged into
Linus's tree, here's a small series with the following changes:
- Converts clk-composite from round_rate() to determine_rate()
- Removes the round_rate() clk op
- Removes the deprecated functions divider_round_rate(),
divider_round_rate_parent(), and divider_ro_round_rate_parent() since
these are just wrappers for the corresponding determine_rate variant

I stumbled upon "isolcpus=managed_irq" which is the last piece which
can only be handled by isolcpus= and has no runtime knob. I knew roughly
what managed interrupts should do but I lacked some details how it is
used and what the managed_irq sub parameter means in practise.
This documents what we have as of today and how it works. I added some
examples how the parameter affects the configuration. Did I miss
something?
Given that the spreading as computed group_cpus_evenly() does not take
the mask of isolated CPUs into account I'm not sure how relevant the
managed_irq argument is. The virtio_scsi driver has no way to limit the
interrupts and I don't see this for the nvme. Even if the number of
queues can be reduced to two (as in the example) it is still spread
evenly in the system instead and the isolated CPUs are not taken into
account.
To make this worse, you can even argue further whether or not the
application on the isolated CPU wants to receive the interrupt directly
or would prefer not to.
Given all this, I am not sure if it makes sense to add 'io_queue' to the
mix or if it could be incorporated into 'managed_irq'.
One more point: Given that isolcpus= is marked deprecated as of commit
b0d40d2b22fe4 ("sched/isolation: Document isolcpus= boot parameter flags, mark it deprecated")
and the 'managed_irq' is evaluated at device's probe time it would
require additional callbacks to re-evaluate the situation. Probably for
'io_queue', too. Does is make sense or should we simply drop the
"deprecation" notice and allowing using it long term?
Dynamic partitions work with cpusets, there this (managed_irq)
limitation but is it really? And if static partition is the use case why
bother.

On s390, an individual PCI function can generally be identified by two
identifiers, the FID and the UID. Which identifier is used depends on
the scope and the platform configuration.
The first identifier, the FID, is always available and identifies a PCI
device uniquely within a machine. The FID may be virtualized by
hypervisors, but on the LPAR level, the machine scope makes it
impossible to create the same configuration based on FIDs on two
different LPARs of the same machine, and difficult to reuse across
machines.
Such matching LPAR configurations are useful, though, allowing
standardized setups and booting a Linux installation on different LPARs.
To this end the UID, or user-defined identifier, was introduced. While
it is only guaranteed to be unique within an LPAR and only if indicated
by firmware, it allows users to replicate PCI device setups.
On s390, which uses a machine hypervisor, a per PCI function hotplug
model is used. The shortcoming with the UID then is, that it is not
visible to the user without first attaching the PCI function and
accessing the "uid" device attribute. The FID, on the other hand, is
used as the slot name and is thus known even with the PCI function in
standby.
Remedy this shortcoming by providing the UID as an attribute on the slot
allowing the user to identify a PCI function based on the UID without
having to first attach it. Do this via a macro mechanism analogous to
what was introduced by commit 265baca69a07 ("s390/pci: Stop usurping
pdev->dev.groups") for the PCI device attributes.

The bridge-stp usermode helper is currently restricted to the initial
network namespace, preventing userspace STP daemons (e.g. mstpd) from
operating on bridges in other network namespaces. Since commit
ff62198553e4 ("bridge: Only call /sbin/bridge-stp for the initial
network namespace"), bridges in non-init namespaces silently fall
back to kernel STP with no way to use userspace STP.
Add a new bridge attribute IFLA_BR_STP_MODE that allows explicit
per-bridge control over STP mode selection:
BR_STP_MODE_AUTO (default) - Existing behavior: invoke the
/sbin/bridge-stp helper in init_net only; fall back to kernel STP
if it fails or in non-init namespaces.
BR_STP_MODE_USER - Directly enable userspace STP (BR_USER_STP)
without invoking the helper. Works in any network namespace.
Userspace is responsible for ensuring an STP daemon manages the
bridge.
BR_STP_MODE_KERNEL - Directly enable kernel STP (BR_KERNEL_STP)
without invoking the helper.
The mode can only be changed while STP is disabled, or set to the
same value (-EBUSY otherwise). IFLA_BR_STP_MODE is processed before
IFLA_BR_STP_STATE in br_changelink(), so both can be set atomically
in a single netlink message. The mode can also be changed in the
same message that disables STP.
The stp_mode struct field is u8 since all possible values fit, while
NLA_U32 is used for the netlink attribute since it occupies the same
space in the netlink message as NLA_U8.
A new stp_helper_active boolean tracks whether the /sbin/bridge-stp
helper was invoked during br_stp_start(), so that br_stp_stop() only
calls the helper for stop when it was called for start. This avoids
calling the helper asymmetrically when stp_mode changes between
start and stop.

C1-Pro acknowledges DVMSync messages before completing the SME/CME
memory accesses. Work around this by issuing an IPI to the affected CPUs
if they are running in EL0 with SME enabled.
Note that we avoid the local DSB in the IPI handler as the kernel runs
with SCTLR_EL1.IESB=1. This is sufficient to complete SME memory
accesses at EL0 on taking an exception to EL1. On the return to user
path, no barrier is necessary either. See the comment in
sme_set_active() and the more detailed explanation in the link below.
To avoid a potential IPI flood from malicious applications (e.g.
madvise(MADV_PAGEOUT) in a tight loop), track where a process is active
via mm_cpumask() and only interrupt those CPUs.

* Add ops.quiescent() and ops.runnable() to the sched_change path.

(e.g. nice, affinity), it goes through dequeue() -> quiescent() ->
(property change callback, e.g. ops.set_weight()) -> runnable() ->
enqueue().
* Change && to || in ops.enqueue() condition. We want to enqueue tasks
that have a non-zero slice and are not in any DSQ.
* Call ops.dispatch() and ops.dequeue() only for tasks that have had
ops.enqueue() called. This is to account for tasks direct-dispatched
from ops.select_cpu().
* Add a note explaining that the pseudo-code provides a simplified view
of the task lifecycle and list some examples of cases that the

RTL8211FS(I)(-VS)-CG, RTL8211FG(I)(-VS)-CG PHYs. Introduce DT properties
'realtek,clkout-ssc-enable', 'realtek,rxc-ssc-enable' and
'realtek,sysclk-ssc-enable' which control CLKOUT, RXC and SYSCLK
SSC spread spectrum clocking enablement on these signals. These
clock are not exposed via the clock API, therefore assigned-clock-sscs
property does not apply.
