Since acpi_processor_notify() can be called before registering a cpufreq
driver or even in cases when a cpufreq driver is not registered at all,
cpufreq_update_limits() needs to check if a cpufreq driver is present
and prevent it from being unregistered.
For this purpose, make it call cpufreq_cpu_get() to obtain a cpufreq
policy pointer for the given CPU and reference count the corresponding
policy object, if present.

Pull MM updates from Andrew Morton:
- The series "Enable strict percpu address space checks" from Uros
Bizjak uses x86 named address space qualifiers to provide
compile-time checking of percpu area accesses.
This has caused a small amount of fallout - two or three issues were
reported. In all cases the calling code was found to be incorrect.
- The series "Some cleanup for memcg" from Chen Ridong implements some
relatively monir cleanups for the memcontrol code.
- The series "mm: fixes for device-exclusive entries (hmm)" from David
Hildenbrand fixes a boatload of issues which David found then using
device-exclusive PTE entries when THP is enabled. More work is
needed, but this makes thins better - our own HMM selftests now
succeed.
- The series "mm: zswap: remove z3fold and zbud" from Yosry Ahmed
remove the z3fold and zbud implementations. They have been deprecated
for half a year and nobody has complained.
- The series "mm: further simplify VMA merge operation" from Lorenzo
Stoakes implements numerous simplifications in this area. No runtime
effects are anticipated.
- The series "mm/madvise: remove redundant mmap_lock operations from
process_madvise()" from SeongJae Park rationalizes the locking in the
madvise() implementation. Performance gains of 20-25% were observed
in one MADV_DONTNEED microbenchmark.
- The series "Tiny cleanup and improvements about SWAP code" from
Baoquan He contains a number of touchups to issues which Baoquan
noticed when working on the swap code.

- The series "mm/damon/core: fix wrong and/or useless damos_walk()
behaviors" from SeongJae Park fixes a few issues with the accuracy of
kdamond's walking of DAMON regions.
- The series "expose mapping wrprotect, fix fb_defio use" from Lorenzo
Stoakes changes the interaction between framebuffer deferred-io and
core MM. No functional changes are anticipated - this is preparatory
work for the future removal of page structure fields.
- The series "mm/damon: add support for hugepage_size DAMOS filter"
from Usama Arif adds a DAMOS filter which permits the filtering by
huge page sizes.
- The series "mm: permit guard regions for file-backed/shmem mappings"
from Lorenzo Stoakes extends the guard region feature from its
present "anon mappings only" state. The feature now covers shmem and
file-backed mappings.
- The series "mm: batched unmap lazyfree large folios during
reclamation" from Barry Song cleans up and speeds up the unmapping
for pte-mapped large folios.
- The series "reimplement per-vma lock as a refcount" from Suren
Baghdasaryan puts the vm_lock back into the vma. Our reasons for
pulling it out were largely bogus and that change made the code more
messy. This patchset provides small (0-10%) improvements on one
microbenchmark.

powerpc, sparc and x86 lazy MMU implementations. Ryan did this in
preparation for implementing lazy mmu mode for arm64 to optimize
vmalloc.
- The series "mm/page_alloc: Some clarifications for migratetype
fallback" from Brendan Jackman reworks some commentary to make the

reduce boot time by tuning the parallalization of huge page
initialization.
- The series "Fix calculations in trace_balance_dirty_pages() for cgwb"
from Tang Yizhou fixes the tracing output from the dirty page
balancing code.
- The series "mm/damon: make allow filters after reject filters useful

reject filters. Behaviour is made more consistent and the documention
is updated accordingly.
- The series "Switch zswap to object read/write APIs" from Yosry Ahmed
updates zswap to the new object read/write APIs and thus permits the
removal of some legacy code from zpool and zsmalloc.
- The series "Some trivial cleanups for shmem" from Baolin Wang does as
it claims.

nvme_map_user_request() is called from both nvme_submit_user_cmd() and
nvme_uring_cmd_io(). But the ioucmd branch is only applicable to
nvme_uring_cmd_io(). Move it to nvme_uring_cmd_io() and just pass the
resulting iov_iter to nvme_map_user_request().
For NVMe passthru operations with fixed buffers, the fixed buffer lookup
happens in io_uring_cmd_import_fixed(). But nvme_uring_cmd_io() can
return -EAGAIN first from nvme_alloc_user_request() if all tags in the
tag set are in use. This ordering difference is observable when using
UBLK_U_IO_{,UN}REGISTER_IO_BUF SQEs to modify the fixed buffer table. If
the NVMe passthru operation is followed by UBLK_U_IO_UNREGISTER_IO_BUF
to unregister the fixed buffer and the NVMe passthru goes async, the
fixed buffer lookup will fail because it happens after the unregister.
Userspace should not depend on the order in which io_uring issues SQEs
submitted in parallel, but it may try submitting the SQEs together and
fall back on a slow path if the fixed buffer lookup fails. To make the
fast path more likely, do the import before nvme_alloc_user_request().

Instead of mapping and unmapping the completion queues memory to the
host PCI address space whenever nvmet_pci_epf_cq_work() is called, map
a completion queue to the host PCI address space when the completion
queue is created with nvmet_pci_epf_create_cq() and unmap it when the
completion queue is deleted with nvmet_pci_epf_delete_cq().
This removes the completion queue mapping/unmapping from
nvmet_pci_epf_cq_work() and significantly increases performance. For
a single job 4K random read QD=1 workload, the IOPS is increased from
23 KIOPS to 25 KIOPS. Some significant throughput increasde for high
queue depth and large IOs workloads can also be seen.
Since the functions nvmet_pci_epf_map_queue() and
nvmet_pci_epf_unmap_queue() are called respectively only from
nvmet_pci_epf_create_cq() and nvmet_pci_epf_delete_cq(), these functions
are removed and open-coded in their respective call sites.

An erroneous message is written to the kernel log when either of the
following actions are taken by a user:
1. Assign an adapter or domain to a vfio_ap mediated device via its sysfs
assign_adapter or assign_domain attributes that would result in one or
more AP queues being assigned that are already assigned to a different
mediated device. Sharing of queues between mdevs is not allowed.
2. Reserve an adapter or domain for the host device driver via the AP bus
driver's sysfs apmask or aqmask attribute that would result in providing
host access to an AP queue that is in use by a vfio_ap mediated device.
Reserving a queue for a host driver that is in use by an mdev is not
allowed.
In both cases, the assignment will return an error; however, a message like
the following is written to the kernel log:
vfio_ap_mdev e1839397-51a0-4e3c-91e0-c3b9c3d3047d: Userspace may not
re-assign queue 00.0028 already assigned to \
e1839397-51a0-4e3c-91e0-c3b9c3d3047d
Notice the mdev reporting the error is the same as the mdev identified
in the message as the one to which the queue is being assigned.
It is perfectly okay to assign a queue to an mdev to which it is
already assigned; the assignment is simply ignored by the vfio_ap device
driver.
This patch logs more descriptive and accurate messages for both 1 and 2
above to the kernel log:
Example for 1:
vfio_ap_mdev 0fe903a0-a323-44db-9daf-134c68627d61: Userspace may not assign
queue 00.0033 to mdev: already assigned to \
62177883-f1bb-47f0-914d-32a22e3a8804
Example for 2:
vfio_ap_mdev 62177883-f1bb-47f0-914d-32a22e3a8804: Can not reserve queue

During the v6.14-rc cycles, there has been an issue with syscons which
prevented TI chipid controller to probe, itself preventing the only DMA
engine on AM62A with the memcpy capability to probe, which is needed for
the SPI controller to work in its most efficient configuration.
The SPI controller on AM62A can be used in DAC and INDAC mode, which are
some kind of direct mapping vs. CPU-controlled SPI operations,
respectively. However, because of hardware constraints (some kind of
request line not being driven), INDAC mode cannot leverage DMA without
risking to underflow the SPI FIFO. This mode costs a lot of CPU
cycles. On the other side however, DAC mode can be used with and without
DMA support, but in practice, DMA transfers are way more efficient
because of the burst capabilities that the CPU does not have.
As a result, in terms of read throughput, using a Winbond chip in 1-8-8
SDR mode, we get:
- 3.5MiB/s in DAC mode without DMA
- 9.0MiB/s in INDAC mode (CPU more busy)
- a fluctuating 9 to 12MiB/s in DAC mode with DMA (a constant 14.5MiB/s
without CPUfreq)
The reason for the patch that is being reverted is that because of the
syscon issue, we were using a very un-efficient DAC configuration (no
DMA), but since:
commit 5728c92ae112 ("mfd: syscon: Restore device_node_to_regmap() for non-syscon nodes")
the probing of the DMA controller has been fixed, and the performances are
back to normal, so we can safely revert this commit.
This is a revert of:
commit cce2200dacd6 ("spi: cadence-qspi: Improve spi memory performance")

After resume/online turbo limit ratio (TRL) is restored partially if
the admin explicitly changed TRL from user space.
A hash table is used to store SST mail box and MSR settings when modified
to restore those settings after resume or online. This uses a struct
isst_cmd field "data" to store these settings. This is a 64 bit field.
But isst_store_new_cmd() is only assigning as u32. This results in
truncation of 32 bits.
Change the argument to u64 from u32.

T495, T495s, and E560 laptops have the FANG+FANW ACPI methods
(therefore fang_handle and fanw_handle are not NULL) but they do not
actually work, which results in a "No such device or address" error.
The DSDT table code for the FANG+FANW methods doesn't seem to do
anything special regarding the fan being secondary. The bug was
introduced in commit 57d0557dfa49 ("platform/x86: thinkpad_acpi: Add
Thinkpad Edge E531 fan support"), which added a new fan control method
via the FANG+FANW ACPI methods.
Add a quirk for T495, T495s, and E560 to avoid the FANG+FANW methods.
Fan access and control is restored after forcing the legacy non-ACPI
fan control method by setting both fang_handle and fanw_handle to NULL.

Some subdrivers make use of the global reference tpacpi_pdev during
initialization, which is called from the platform driver's probe.
However, after the commit 38b9ab80db31 ("platform/x86: thinkpad_acpi:
Move subdriver initialization to tpacpi_pdriver's probe.") this
variable is only properly initialized *after* probing and this can
result in a NULL pointer dereference.
In order to fix this without reverting the commit, register the platform
bundle in two steps, first create and initialize tpacpi_pdev, then
register the driver synchronously with platform_driver_probe(). This way
the benefits of commit 38b9ab80db31 are preserved.
Additionally, the commit 43fc63a1e8f6 ("platform/x86: thinkpad_acpi:
Move HWMON initialization to tpacpi_hwmon_pdriver's probe") introduced
a similar problem, however tpacpi_sensors_pdev is only used once inside
the probe, so replace the global reference with the one given by the
probe.

section "Software reset":
"There is a low probability that some devices will have corruption of the
registers after the automatic power-on reset if the device is powered up
with a residual VDD level. It is required that the VDD starts at zero volts
at power up or upon power cycling to ensure that there is no corruption of
the registers. If this is not possible, a reset must be initiated after
power-up (i.e. when power is stable) with the software reset command"

invalid
Prior to commit 496121c02127 ("ACPI: processor: idle: Allow probing on
platforms with one ACPI C-state"), the acpi_idle driver wouldn't load on
systems without a valid C-State at least as deep as C2.
The behavior was desirable for guests on hypervisors such as VMWare
ESXi, which by default don't have the _CST ACPI method, and set the C2
and C3 latencies to 101 and 1001 microseconds respectively via the FADT,
to signify they're unsupported.
Since the above change though, these virtualized deployments end up
loading acpi_idle, and thus entering the default C1 C-State set by
acpi_processor_get_power_info_default(); this is undesirable for a
system that's communicating to the OS it doesn't want C-States (missing
_CST, and invalid C2/C3 in FADT).
Make acpi_processor_get_power_info_fadt() return -ENODEV in that case,
so that acpi_processor_get_cstate_info() exits early and doesn't set
pr->flags.power = 1.

The I3C master driver may receive an IBI from a target device that has not
been probed yet. In such cases, the master calls `i3c_master_queue_ibi()`
to queue an IBI work task, leading to "Unable to handle kernel read from
unreadable memory" and resulting in a kernel panic.
Typical IBI handling flow:
1. The I3C master scans target devices and probes their respective drivers.
2. The target device driver calls `i3c_device_request_ibi()` to enable IBI
and assigns `dev->ibi = ibi`.
3. The I3C master receives an IBI from the target device and calls
`i3c_master_queue_ibi()` to queue the target device driver’s IBI
handler task.
However, since target device events are asynchronous to the I3C probe
sequence, step 3 may occur before step 2, causing `dev->ibi` to be `NULL`,
leading to a kernel panic.
Add a NULL pointer check in `i3c_master_queue_ibi()` to prevent accessing
an uninitialized `dev->ibi`, ensuring stability.

git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux
Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:
- Extract the 'pin-init' API from the 'kernel' crate and make it into
a standalone crate.
In order to do this, the contents are rearranged so that they can
easily be kept in sync with the version maintained out-of-tree that
other projects have started to use too (or plan to, like QEMU).
This will reduce the maintenance burden for Benno, who will now
have his own sub-tree, and will simplify future expected changes
like the move to use 'syn' to simplify the implementation.
- Add '#[test]'-like support based on KUnit.
We already had doctests support based on KUnit, which takes the
examples in our Rust documentation and runs them under KUnit.
Now, we are adding the beginning of the support for "normal" tests,
similar to those the '#[test]' tests in userspace Rust. For
instance:
#[kunit_tests(my_suite)]
mod tests {
#[test]
fn my_test() {
assert_eq!(1 + 1, 2);
}
}
Unlike with doctests, the 'assert*!'s do not map to the KUnit
assertion APIs yet.
- Check Rust signatures at compile time for functions called from C
by name.
In particular, introduce a new '#[export]' macro that can be placed
in the Rust function definition. It will ensure that the function
declaration on the C side matches the signature on the Rust
function:
#[export]
pub unsafe extern "C" fn my_function(a: u8, b: i32) -> usize {
// ...
}
The macro essentially forces the compiler to compare the types of
the actual Rust function and the 'bindgen'-processed C signature.
These cases are rare so far. In the future, we may consider
introducing another tool, 'cbindgen', to generate C headers
automatically. Even then, having these functions explicitly marked
may be a good idea anyway.
- Enable the 'raw_ref_op' Rust feature: it is already stable, and
allows us to use the new '&raw' syntax, avoiding a couple macros.
After everyone has migrated, we will disallow the macros.
- Pass the correct target to 'bindgen' on Usermode Linux.
- Fix 'rusttest' build in macOS.
'kernel' crate:
- New 'hrtimer' module: add support for setting up intrusive timers
without allocating when starting the timer. Add support for
'Pin<Box<_>>', 'Arc<_>', 'Pin<&_>' and 'Pin<&mut _>' as pointer
types for use with timer callbacks. Add support for setting clock
source and timer mode.
- New 'dma' module: add a simple DMA coherent allocator abstraction
and a test sample driver.
- 'list' module: make the linked list 'Cursor' point between
elements, rather than at an element, which is more convenient to us
and allows for cursors to empty lists; and document it with
examples of how to perform common operations with the provided
methods.

Pull clk updates from Stephen Boyd:
"Here's the pile of clk driver patches. The usual suspects^Wsilicon
vendors are all here, adding new SoC support and fixing existing code.
There are a few patches to the clk framework here as well. They've
been baking in linux-next for weeks so I'm hoping we don't have to
revert them. The disable OF node patch is probably the scariest one
although it seems unlikely that a system would be relying on a driver
_not_ probing because the clk never appeared, but you never know.
Nothing looks out of the ordinary on the driver side but that's
because it's mostly a bunch of data.
Core:
- Use dev_err_probe() in the clk registration path (Peering into the
crystal ball shows many patches that remove printks)
- Check for disabled OF nodes in of_clk_get_hw_from_clkspec()
New Drivers:
- Allwinner A523/T527 clk driver
- Qualcomm IPQ9574 NSS clk driver
- Qualcomm QCS8300 GPU and video clk drivers
- Qualcomm SDM429 RPM clks
- Qualcomm QCM6490 LPASS (low power audio) resets
- Samsung Exynos2200: driver for several clock controllers (Alive,
CMGP, HSI, PERIC/PERIS, TOP, UFS and VFS)
- Samsung Exynos7870: Driver for several clock controllers (Alive,
MIF, DISP AUD, FSYS, G3D, ISP, MFC and PERI)
- Rockchip rk3528 and rk3562 clk driver
Updates:
- Various fixes to SoC clk drivers for incorrect data, avoid touching
protected registers, etc.
- Additions for some missing clks in existing SoC clk drivers
- DT schema conversions from text to YAML
- Kconfig cleanups to allow drivers to be compiled on moar
architectures"
