Merge series from Krzysztof Kozlowski <krzysztof.kozlowski@oss.qualcomm.com>:
Use container_of_const(), which is preferred over container_of(), when
the argument 'ptr' and returned pointer are already const, for better
code safety and readability.
Some drivers already have const everywhere, so container_of_const can be
directly used. In few other drivers, the final pointer can be constified
that way.

Expose the current system-defined list of housekeeping CPUs in a new
sysfs file: /sys/devices/system/cpu/housekeeping.
This provides userspace performance tuning tools and resource managers
with a canonical, reliable method to accurately identify the cores
responsible for essential kernel maintenance workloads (RCU, timer
callbacks, and unbound workqueues). Currently, tooling must manually
calculate the housekeeping set by parsing complex kernel boot parameters
(like isolcpus= and nohz_full=) and system topology, which is prone to
error. This dedicated file simplifies the configuration of low-latency
workloads.

This patch introduces a new UIO driver, uio_pci_generic_sva, which
extends the functionality of uio_pci_generic by adding support for
Shared Virtual Addressing (SVA) when IOMMU is enabled in the system.
The key enhancement allows PCI devices to directly use user-space virtual
addresses for DMA operations, eliminating the need for bounce buffers or
explicit IOVA mapping. This is achieved by leveraging the kernel's IOMMU-SVA
subsystem, including process address space attachment, page fault handling,
and shared context management between CPU and device.
With this driver, userspace applications can perform zero-copy DMA using
native pointers:
void *addr = malloc(N);
set_dma_addr((uint64_t)addr); // Passing user VA directly
start_dma();
The device can now access 'addr' through the IOMMU's PASID-based translation,
provided that the underlying IOMMU hardware (e.g., Intel VT-d 3.1+, AMD-Vi,
ARM SMMU, RISCV IOMMU) and platform support SVA.
Dependencies:
- CONFIG_IOMMU_SVA must be enabled.
- The platform must support PRI (Page Request Interface) and PASID.
- Device drivers/userspace must handle page faults if demand-paging is used.
The implementation reuses core logic from uio_pci_generic.c while adding
PASID setting, and integration with the IOMMU SVA APIs.
Also, add a read-only sysfs attribute 'pasid' to expose the Process Address
Space ID assigned by IOMMU driver when binding an SVA-enabled device.
For details, refer to the ABI documentation for uio_pci_sva driver sysfs attribute
(Documentation/ABI/testing/sysfs-driver-uio_pci_sva-pasid).

The CAN cores on Polarfire SoC both have a reset. The platform firmware

during normal operation. The resets should have been made required, but
this is one of the things that can happen when the binding is written
without driver support.

Qualcomm driver updates for v6.19
Support for hardware-keymanager v1 support for wrapped keys is introduce
in the ICE driver.
Support for the new Kaanapali mobile platform is added to last-level
cache controller, pd-mapper, and UBWC drivers.
UBWC driver gains support for the Monaco and Glymur platforms.
The PMIC GLINK driver is extended to handle the differences found in
targets where the related firmware runs on the SoCCP.
Support for running on targets without initialized SMEM is provided, by
reworking the SMEM driver to differentiate between "not yet probed" and
"probed but there was no SMEM". An unwanted WARN_ON() that triggered if
clients asked for a SMEM item beyond the currently running system's
limit, was removed, to allow new use cases to gracefully fail on old
targets.
The Qualcomm socinfo driver is extended with support for version 20
through 23 and support for providing version information about more than
32 remote processors. Identifiers for QCS6490 and SM8850 are also added.
Additionally, a number of smaller bug fixes and cleanups in PBS, OCMEM,
GSBI, TZMEM, and MDT-loader are included.

Add "aspeed,ast2700-mdio" compatible to the binding schema with a fallback
to "aspeed,ast2600-mdio".
Although the MDIO controller on AST2700 is functionally the same as the
one on AST2600, it's good practice to add a SoC-specific compatible for
new silicon. This allows future driver updates to handle any 2700-specific
integration issues without requiring devicetree changes or complex
runtime detection logic.
For now, the driver continues to bind via the existing
"aspeed,ast2600-mdio" compatible, so no driver changes are needed.

This was added by commit 099ada2c8726 ("io_uring/rw: add write support
for IOCB_DIO_CALLER_COMP") and disabled a little later by commit
838b35bb6a89 ("io_uring/rw: disable IOCB_DIO_CALLER_COMP") because it
didn't work. Remove all the related code that sat unused for 2 years.

Since v4.6 the BUDDY flag is set for _all_ pages in the block
and no longer just for the first one.
This change was introduced by:
commit 832fc1de01ae ("/proc/kpageflags: return KPF_BUDDY for "tail" buddy pages")
Strictly speaking, this was an ABI change, but as nobody has noticed
since 2016, let's just update the documentation.

Change page_free to folio_free to make the folio support for
zone device-private more consistent. The PCI P2PDMA callback
has also been updated and changed to folio_free() as a result.
For drivers that do not support folios (yet), the folio is
converted back into page via &folio->page and the page is used
as is, in the current callback implementation.

After recovering from a PCI error through reset, affected devices are in
D0_uninitialized state and need to be brought into D0_active state by
re-initializing their Config Space registers (PCIe r7.0 sec 5.3.1.1).
To facilitate that, the PCI core provides pci_restore_state() and
pci_save_state() helpers. Document rules governing their usage.
As Bjorn notes, so far no file in "Documentation/ includes anything about
the idea of a driver using pci_save_state() to capture the state it wants
to restore after an error", even though it is a common pattern in drivers.
So that's obviously a gap that should be closed.

Some devices reserve a larger NVMEM region for the U-Boot environment
than the actual environment data length used by U-Boot itself. The CRC32
in the U-Boot header is calculated over the smaller data length, causing
CRC validation to fail when Linux reads the full partition.
Allow an optional device tree property "env-size" to specify the
environment data size to use for CRC computation.
