Pull power management fixes from Rafael Wysocki:
"These fix issues related to cpufreq, in the ACPI CPPC library and the
generic CPPC cpufreq driver, in the powernow-k8 and amd-pstate
drivers, and in the schedutil governor:
- Allow fast frequency switching in the ACPI CPPC library only when
every supported control used by the driver callback has an address
space already accepted for fast access (Christian Loehle)
- Skip writes to unsupported performance controls in the ACPI CPPC
library (Christian Loehle)
- Update cppc_cpufreq_update_perf_limits() to read policy->min and
policy->max once and, if the lockless snapshot is inconsistent,
reduce the minimum to the observed maximum, along the lines of
cpufreq_driver_resolve_freq() (Christian Loehle)
- Fix a possible memory leak in the powernowk8_cpu_init() error paths
(Abdun Nihaal)
- Loosen the requirement on lowest nonlinear frequency != min freq in
the amd-pstate driver that is too tight for new systems some of
which actually have the lowest nonlinear frequency identical to the
minimum frequency (Mario Limonciello)
- Prevent amd-pstate from loading on unsupported hardware (Rong
Zhang)
- Address an initialization race in the schedutil governor when it
runs on multi-CPU cpufreq policies, by making it initialize all
per-CPU structures first and only then publish the per-CPU
utilization update hooks (Zhongqiu Han)"

Add a framework driver for Dreamchip RPPX1 ISP. The driver aims to
provide a framework for other V4L2 based drivers to drive the RPPX1
functionality. The reason for this split is that the RPPX1 IP itself do
not provide any DMA engines to drive data to/from the device, instead it
depends on other IP blocks to implement these features.
While the peripherals around the RPPX1 ISP used in different designs and
by different vendors are different the RPPX1 core itself is the same.
For this reason the framework solution to be able to split the Dreamchip
RPPX1 driver from vendors usage of it have been picked in hope to reduce
duplication of the common parts.
The design is to try and keep the surface of this framework as small as
possible. The intention of this change is to be able to fill all needs
of this.
* Two functions to create and destroy a RPPX1 instance, rppx1_create()
and rppx1_destory(). These are intended to be called in the users
probe and remove code paths.
* Two functions to start and stop the RPPX1 processing, rppx1_start()
and rppx1_stop(). These are intended to be called in the users
stream on and stream off code paths.
* One function to ask the RPPX1 to process parameters buffer prepared
by user space, rppx1_params(). The intention is to call this
function when the parameter buffer is queued to the V4L2 driver and
the result stored by the driver until the time it needs to be
written to the RPPX1. It's the users responsibility to write it
either using MMIO or other means.
* One function to fill in a statistic buffer based on the current
status of the RPPX1, rppx1_stats_fill_isr(). The intention is that
the user call's this in its interrupt handler when it knows the
RPPX1 is done processing a frame.
* One function to ack and retrieve the interrupts generated by the
RPPX1, rppx1_interrupt(). The intention is to call this function
when the users interrupt handler detects the RPPX1 have raised and
interrupt. There is no need for the user to understand, or act, on
the actual RPPX1 interrupt, but it can if it wants too.
The initial support in the framework is limited and do not implement any
ISP processing algorithms other then configuring the RPPX1 to process
any Bayer (8-, 10, or 12-bit) image and produce either a RGB or YUYV
output. It do however probe all function blocks of the RPPX1 and provide
an interface to interact with both parameter and statistic bufferers.
The user of the framework will not change as algorithms for the
different function blocks of the ISP are being added.

Add the scaffolding for the parameters and statistics buffers for
Dreamchip RPPX1. The parameters for each ISP function block will be
added together with the logic for it.
In addition to the scaffolding add a common struct that describes the
measurement window. This struct is not specific to any block and will
used by many of them.

Add two helper functions to v4l2-isp to handle statistics:
- v4l2_isp_stats_init_buffer() to initialize a statistics buffer
- v4l2_isp_stats_init_block() to initialize a statistics block in the
next available memory location of a buffer
The v4l2_isp_stats_init_buffer() resets the data size counter of the
buffer and initializes its 'version' field.
The v4l2_isp_stats_init_block() helper accepts the type of the stats
block about to be populated, an array of per-block-type information and
the maximum size of the v4l2-isp buffer. If enough space for the new
block is available, the function increments the
v4l2_isp_buffer.data_size counter, initializes the new stats block
header and returns a pointer to the block for the driver to populate it.

Drivers are expected to provide to the helper function
v4l2_isp_params_validate_buffer() a list of 'struct
v4l2_isp_params_block_type_info' entries, one for each supported ISP block.
The type 'struct v4l2_isp_params_block_type_info' so far only contained the
expected block size for the core framework to validate the declared block
size against the expected one.
For some blocks, drivers might want to implement more precise per-block
validations. Add a function pointer member to 'struct
v4l2_isp_params_block_type_info' to allow drivers to register a callback
and call it from the core framework during validation.

hardware versions reporting different statistics data with less impact on

The problem scenario:
If we have a folio mmapped shared and then somebody does a dio read with
that folio as the read destination, then it is possible that the dio
will see a dirty destination page when it starts (and thus skip
dirtying and just GUP pin it) but then while it is doing the read, btrfs
finishes writing it back and by the endio, the folio is clean. In that
case, the dio read must re-dirty the folio with aops->dirty_folio():
btrfs_check_read_bio()
|- __iomap_dio_bio_end_io() from btrfs_bio_end_io()
|- bio_check_pages_dirty()
|- bio_dirty_fn()
|- bio_release_pages(bio, true)
|- __bio_release_pages(bio, mark_dirty == true)
|- folio_lock()
|- folio_mark_dirty()
|- aops->dirty_folio()
|- folio_unlock()
A data block normally moves through writeback as follows:
TASK
folio_lock
write clean -> dirty bit + delalloc
folio_unlock
WRITEBACK
for-each-dirty-folio:
folio_lock
run_delalloc delalloc consumed -> dirty bit + OE
submission dirty bit consumed -> writeback bit + OE
folio_unlock
ENDIO
endio OE bytes accounted
OE finish writeback -> clean; destroy OE
Three critical invariants that this path maintains are:
I1. Any dirty block is covered by delalloc xor an ordered extent
I2. Any dirty block covered by an OE will be submitted into that OE
I3. Any dirty block already submitted into an OE will not be submitted
again into the same OE.
These ensure that the block will be written exactly once. It is clear
that not reserving delalloc for the re-dirty case violates I1.
This situation, even without bs < folio_size, has long required btrfs to
fixup such dirty pages during writeback with an asynchronous worker that
is allowed to do this expensive work and writeback does not proceed for
a folio while it is doing this work.
Commit 247e743cbe6e ("Btrfs: Use async helpers to deal with pages that
have been improperly dirtied") introduced the COW fixup to catch exactly
this class at writeback, way back in 2008.
Since then, there have been many advances to prevent most of the causes
of such re-dirtying and we thought we could get away with removing the
annoying cow-fixup in the hope of simplifying writeback for large folio
support.
Commit b2a9f217ad3f ("btrfs: remove the COW fixup mechanism")
Commit 4927b141877c ("btrfs: remove folio ordered flag and subpage bitmap")
Since it turns out this assumption was incorrect, as evidenced by the
report and attendant reproducers, we must reintroduce the fixup concept.
This is of course critically further complicated by bs < folio_size. In
that case, rather than just a folio dirty bit, we have a bitmap for the
dirty blocks in the folio. And the (also broken) invariant is:
I4. folio dirty IFF at least one block bitmap dirty.
The original report of a stall on a misinterpreted empty bitmap is
exactly evidence of a violation of I4.
It is exactly because of bs < folio_size we don't want to simply revert the
removal patches. The original fixup was not properly bs < folio_size
aware, which motivated removal in the first place. So we wish to build a
bs < folio_size aware fixup.
One other important detail from the old design, any normal write that
happens after a re-dirty but before a fixup is racing with the cow fixup
to do the delalloc reservation, therefore it must cancel the fixup state.
If it arrives after the reservation exists, it will be a normal dirty
overwrite. This critically informs the design in a pretty clear way.
fixup requiring re-dirty has folio granularity, while cancellation has
delalloc (block) granularity so while we only ever produce fixup in
chunks of folios, we must be able to clear it in blocks. Therefore we
must track the blocks needing fixup at block granularity.
The obvious way to do this is with a new bitmap in btrfs_folio_state,
but it is desirable to avoid that if possible. Unfortunately, I don't
think it is possible and the reason is subtle and leans on a sort of
extreme reproducer, but I think can be explained relatively succinctly.
Consider a folio whose two halves will land in different ordered extents
(can be accomplished with tricks using nodatasum) and a dio read is
running with it as the shared mmap destination.
1. The front half:
a. folio comes clean on a normal write
b. dio read completes into the folio marking it fixup.
c. a write comes for the previous folio for a range extending into
this folio, this is a cancellation of the fixup which reserves
space.
d. writeback runs on the range *not* overlapping the folio. This half
remains dirty but is now covered by an OE and is awaiting
writeback running on its range to be submitted and finish the OE.
2. The back half:
a. the folio is part of an OE that gets far enough along to clear
writeback.
b. dio read completes into the folio marking it fixup.
After this, the folio's front half is dirty in the "normal" sense, it
needs to be submitted to the OE waiting for it. It's a cancelled fixup.
Meanwhile, the second half is a true fresh fixup. So at this point if we
run writeback on this folio, we genuinely can't know what to do without
block level information. If we submit it, we submit unreserved dirty
from the back half. If we don't, we will never finish the OE waiting for
it. So it's either a corruption or a deadlock.
Thus, the full high level design picture:
- btrfs_data_dirty_folio(): For out of band non-reserving dirties,
mark still-clean blocks inside EOF dirty and set their fixup bits
(the event carries no range, so every clean block is suspect).
Already-dirty blocks are covered or pending and are left alone.
- Writeback: skip fixup blocks and enqueue work for them
- writepage_fixup(): for each fixup block do the fixup reservation in a
worker, after which the blocks can be written back normally.
- Typical reserving write paths cancel fixup state for the ranges they
cover with btrfs_folio_cancel_fixup()

Implement the necessary callbacks to switch the 8250 console driver
to perform as an nbcon console.
Add implementations for the nbcon console callbacks:
->write_atomic()
->write_thread()
->device_lock()
->device_unlock()
and add CON_NBCON to the initial @flags.
All hardware access in the callbacks is within unsafe sections.
The ->write_atomic() and ->write_thread() callbacks allow safe
handover/takeover per byte and add a preceding newline if they
take over from another context mid-line.
For the ->write_atomic() callback, a new irq_work is used to defer
modem control since it may be called from a context that does not
allow waking up tasks. During suspend/resume the irq_work is not

Note: A new __serial8250_clear_IER() is introduced for direct
clearing of UART_IER during console writing (which will not be
holding the port lock for atomic printing or KDB/KGDB). This
allows restoring a lockdep check to serial8250_clear_IER() in

Define a static software node for the UCB1x00 GPIO controller and attach
it to the core MFD device in ucb1x00_probe(). This node will also be
used by the created GPIO chip.
This allows machine subdrivers (such as Assabet evaluation board
support) to reference the UCB1x00 GPIO controller in property entries
when converting legacy platform data to software nodes, resolving pin
bindings directly via the attached firmware node without relying on
name matching.

Move the DBx500 PRCMU definitions into the DB8500 PRCMU

Convert users of simple PRCMU wrappers to call the DB8500 helpers
directly.
The dbx500-prcmu.h header was the result of an earlier attempt to
abstract several DBx5x SoC PRCMU units to use the same abstract
header. They are deleted from the kernel and this is not just
causing maintenance burden and build errors.
The stub code is using -ENOSYS in a way checkpatch complains about

The SI476X driver depends on the legacy GPIO API. As it only
really use a single GPIO for reset, and this can be easily converted
to use a GPIO descriptor, modernize the driver.
The "reset" GPIO is obtained from a device property, such as a
device tree ("reset-gpios", which is standard, but this hardware has
no DT bindings as of now) or a software node for static platforms.
Out-of-tree users can easily adopt to providing a GPIO descriptor
this way.

Add a netpoll_get_carrier_timeout() accessor and export it so netconsole

passed carrier_timeout) and read the parameter directly while the helper

read/write
MHI EP stack makes use of the MHI controller drivers like MHI EPF to do
read/write to the host memory. And that driver is free to use mechanisms
like DMA to offload the read/write operations.
So if DMA is used for offload, then there is no guarantee that those DMA
operations would be completed by the time mhi_ep_remove() gets called. This
can lead to UAF (Use-After-Free) issues as the DMA callback can trigger
xfer_cb() even after mhi_ep_remove() has returned.
So to fix this issue, introduce the mhi_cntrl->flush_async() callback and
call it in mhi_ep_remove() to drain all the in-flight async transfers
before disconnecting the channels.
The completion handlers keep triggering xfer_cb() as long as it is set. So
flushing the transfers after notifying the client about the disconnect
(-ENOTCONN) would still let a success callback slip through afterwards and
lead to the same UAF. So disable the channels first to prevent new
transfers, then flush the in-flight transfers so that their completions are
delivered while xfer_cb() is still valid and only then notify the
disconnect and clear xfer_cb().

MHI bus transitions the device into M3 state during suspend and back to M0
state during resume. But due to hardware issues, some devices do not
support M3 state. To support these devices properly, MHI bus needs to skip
transitioning the device to M3 during suspend and back to M0 during resume.
For this purpose, introduce the 'mhi_cntrl->no_m3' flag and allow it to be
set by the MHI controller drivers. Once set, this flag lets the MHI bus
skip transitioning the device to M3/M0 during suspend/resume.
But, simply skipping suspend/resume for such devices is not sufficient, as
it leaves the MHI host in M0 state with device access enabled. Client
drivers that do not implement PM callbacks (for instance, the non-freezable
rx_refill worker in mhi_net driver) could then keep ringing channel
doorbells and issue MMIO to the device even after the controller driver has
disabled it and moved it to D3 during its own suspend, resulting in access
to a powered down device.
So instead of skipping the entire suspend/resume operation, run the full
host suspend/resume sequence but without the device-side M state handshake.
During suspend, only transition the host to M3 without sending the MHICTRL
M3 command or waiting for the device M3 event. During resume, bring the
host back to M0 through mhi_pm_m0_transition() without sending the MHICTRL
M0 command.
With the host in M3, all device access is gated by MHI_DB_ACCESS_VALID()
and MHI_REG_ACCESS_VALID(), so any transfer queued by the clients during
suspend is deferred until resume, where mhi_pm_m0_transition() rings the
pending doorbells.
