gpio: qixis: select CONFIG_REGMAP_MMIO
The regmap drivers need to be selected by each user, without that there
can be configurations that fail to link:

drivers/xen: use min() instead of min_t()
min_t(unsigned int, a, b) casts an 'unsigned long' to 'unsigned int'. Use min(a, b) instead as it promotes any 'unsigned int' to 'unsigned long' and so cannot discard significant bits. In this case the 'unsigned long' value is small enough that the result is ok. Detected by an extra check added to min_t().

tpm2-sessions: Fix tpm2_read_public range checks
tpm2_read_public() has some rudimentary range checks but the function does
not ensure that the response buffer has enough bytes for the full TPMT_HA
payload.
Re-implement the function with necessary checks and validation, and return
name and name size for all handle types back to the caller.

tpm2-sessions: Fix out of range indexing in name_size
'name_size' does not have any range checks, and it just directly indexes
with TPM_ALG_ID, which could lead into memory corruption at worst.
Address the issue by only processing known values and returning -EINVAL for
unrecognized values.
Make also 'tpm_buf_append_name' and 'tpm_buf_fill_hmac_session' fallible so
that errors are detected before causing any spurious TPM traffic.
End also the authorization session on failure in both of the functions, as
the session state would be then by definition corrupted.

Capabilities patch for v6.19
There is only a single commit,
Clarify the rootid_owns_currentns
which introduces no functional change. Ryan Foster had sent a patch
to add testing of the security/commoncap.c:rootid_owns_currentns()
function. The patch pointed out that this function was not as clear
as it should be.
This commit has two purposes:
1. Clarify the intent of the function in the name
2. Split the function so that the base functionality is easier
to test from a kunit test.
This commit has been in linux-next since November 18 with no reported
issues. Ryan has posted an updated test patch based on this commit.

only works with VFIO. This closes the last functional gap with classic
VFIO type 1 to safely support PCI peer to peer DMA by mapping the VFIO

Pull iommufd updates from Jason Gunthorpe:
"This is a pretty consequential cycle for iommufd, though this pull is
not too big. It is based on a shared branch with VFIO that introduces
VFIO_DEVICE_FEATURE_DMA_BUF a DMABUF exporter for VFIO device's MMIO
PCI BARs. This was a large multiple series journey over the last year
and a half.
Based on that work IOMMUFD gains support for VFIO DMABUF's in its
existing IOMMU_IOAS_MAP_FILE, which closes the last major gap to
support PCI peer to peer transfers within VMs.
In Joerg's iommu tree we have the "generic page table" work which aims
to consolidate all the duplicated page table code in every iommu
driver into a single algorithm. This will be used by iommufd to
implement unique page table operations to start adding new features
and improve performance.
In here:
- Expand IOMMU_IOAS_MAP_FILE to accept a DMABUF exported from VFIO.
This is the first step to broader DMABUF support in iommufd, right
now it only works with VFIO. This closes the last functional gap

VFIO updates for v6.19-rc1
- Move libvfio selftest artifacts in preparation of more tightly
coupled integration with KVM selftests. (David Matlack)
- Fix comment typo in mtty driver. (Chu Guangqing)
- Support for new hardware revision in the hisi_acc vfio-pci variant
driver where the migration registers can now be accessed via the PF.
When enabled for this support, the full BAR can be exposed to the
user. (Longfang Liu)
- Fix vfio cdev support for VF token passing, using the correct size
for the kernel structure, thereby actually allowing userspace to
provide a non-zero UUID token. Also set the match token callback for
the hisi_acc, fixing VF token support for this this vfio-pci variant
driver. (Raghavendra Rao Ananta)
- Introduce internal callbacks on vfio devices to simplify and
consolidate duplicate code for generating VFIO_DEVICE_GET_REGION_INFO
data, removing various ioctl intercepts with a more structured
solution. (Jason Gunthorpe)
- Introduce dma-buf support for vfio-pci devices, allowing MMIO regions
to be exposed through dma-buf objects with lifecycle managed through
move operations. This enables low-level interactions such as a
vfio-pci based SPDK drivers interacting directly with dma-buf capable
RDMA devices to enable peer-to-peer operations. IOMMUFD is also now
able to build upon this support to fill a long standing feature gap
versus the legacy vfio type1 IOMMU backend with an implementation of
P2P support for VM use cases that better manages the lifecycle of the
P2P mapping. (Leon Romanovsky, Jason Gunthorpe, Vivek Kasireddy)
- Convert eventfd triggering for error and request signals to use RCU
mechanisms in order to avoid a 3-way lockdep reported deadlock issue.
(Alex Williamson)
- Fix a 32-bit overflow introduced via dma-buf support manifesting with
large DMA buffers. (Alex Mastro)
- Convert nvgrace-gpu vfio-pci variant driver to insert mappings on
fault rather than at mmap time. This conversion serves both to make
use of huge PFNMAPs but also to both avoid corrected RAS events
during reset by now being subject to vfio-pci-core's use of
unmap_mapping_range(), and to enable a device readiness test after
reset. (Ankit Agrawal)
- Refactoring of vfio selftests to support multi-device tests and split
code to provide better separation between IOMMU and device objects.
This work also enables a new test suite addition to measure parallel
device initialization latency. (David Matlack)

crypto/ccp: Fix CONFIG_PCI=n build
It turns out that the PCI driver for ccp is unconditionally built into the kernel in the CONFIG_PCI=y case. This means that the new SEV-TIO support needs an explicit dependency on PCI to avoid build errors when CONFIG_CRYPTO_DEV_SP_PSP=y and CONFIG_PCI=n.

IOMMU Updates for Linux v6.19
Including:
- Introduction of the generic IO page-table framework with support for
Intel and AMD IOMMU formats from Jason. This has good potential for
unifying more IO page-table implementations and making future
enhancements more easy. But this also needed quite some fixes during
development. All known issues have been fixed, but my feeling is that
there is a higher potential than usual that more might be needed.
- Intel VT-d updates:
- Use right invalidation hint in qi_desc_iotlb().
- Reduce the scope of INTEL_IOMMU_FLOPPY_WA.
- ARM-SMMU updates:
- Qualcomm device-tree binding updates for Kaanapali and Glymur SoCs
and a new clock for the TBU.
- Fix error handling if level 1 CD table allocation fails.
- Permit more than the architectural maximum number of SMRs for funky
Qualcomm mis-implementations of SMMUv2.
- Mediatek driver:
- MT8189 iommu support.
- Move ARM IO-pgtable selftests to kunit.
- Device leak fixes for a couple of drivers.
- Random smaller fixes and improvements.

The reason this happens is because the fwsec-sb firmware image only
supports being booted from a contiguous coherent sysmem allocation. If a
system runs into enough memory fragmentation from memory pressure, such as
what can happen on systems with low amounts of memory, this can lead to a
situation where it later becomes impossible to find space for a large
enough contiguous allocation to hold fwsec-sb. This causes us to fail to
boot the firmware image, causing the GPU to fail booting and causing the
driver to fail.
Since this firmware can't use non-contiguous allocations, the best solution
to avoid this issue is to simply allocate the memory for fwsec-sb during
initial driver-load, and reuse the memory allocation when fwsec-sb needs to
be used. We then release the memory allocations on driver unload.

amdgpu drivers so the PCI core can restore BARs if the resize fails
(Ilpo Järvinen)
- Move Resizable BAR code to rebar.c (Ilpo Järvinen)
- Add pci_rebar_size_supported() and use it in i915 and xe (Ilpo
Järvinen)
- Add pci_rebar_get_max_size() and use it in xe and amdgpu (Ilpo
Järvinen)
Power management and error handling:
- For drivers using PCI legacy suspend, save config state at suspend
so that state (not any earlier state from enumeration, probe, or
error recovery) will be restored when resuming (Lukas Wunner)
- For devices with no driver or a driver that lacks power management,
save config state at hibernate so that state (not any earlier state
from enumeration, probe, or error recovery) will be restored when
resuming (Lukas Wunner)
- Save device config space on device addition, before driver binding,
so error recovery works more reliably (Lukas Wunner)
- Drop pci_save_state() from several drivers that no longer need it
since the PCI core always does it and pci_restore_state() no longer
invalidates the saved state (Lukas Wunner)
- Document use of pci_save_state() by drivers to capture the state
they want restored during error recovery (Lukas Wunner)
Power control:
- Add a struct pci_ops.assert_perst() function pointer to
assert/deassert PCIe PERST# and implement it for the qcom driver
(Krishna Chaitanya Chundru)
- Add DT binding and pwrctrl driver for the Toshiba TC9563 PCIe
switch, which must be held in reset after poweron so the pwrctrl
driver can configure the switch via I2C before bringing up the
links (Krishna Chaitanya Chundru)
Endpoint framework:
- Convert the endpoint doorbell test to use a threaded IRQ to fix a
'sleeping while atomic' issue (Bhanu Seshu Kumar Valluri)
- Add endpoint VNTB MSI doorbell support to reduce latency between
host and endpoint (Frank Li)
New native PCIe controller drivers:
- Add CIX Sky1 host controller DT binding and driver (Hans Zhang)
- Add NXP S32G host controller DT binding and driver (Vincent
Guittot)
- Add Renesas RZ/G3S host controller DT binding and driver (Claudiu
Beznea)
- Add SpacemiT K1 host controller DT binding and driver (Alex Elder)
Amlogic Meson PCIe controller driver:
- Update DT binding to name DBI region 'dbi', not 'elbi', and update
driver to support both (Manivannan Sadhasivam)
Apple PCIe controller driver:
- Move struct pci_host_bridge allocation from pci_host_common_init()
to callers, which significantly simplifies pcie-apple (Marc
Zyngier)
Broadcom STB PCIe controller driver:
- Disable advertising ASPM L0s support correctly (Jim Quinlan)
- Add a panic/die handler to print diagnostic info in case PCIe
caused an unrecoverable abort (Jim Quinlan)
Cadence PCIe controller driver:
- Add module support for Cadence platform host and endpoint
controller driver (Manikandan K Pillai)
- Split headers into 'legacy' (LGA) and 'high perf' (HPA) to prepare
for new CIX Sky1 driver (Manikandan K Pillai)
MediaTek PCIe controller driver:
- Convert DT binding to YAML schema (Christian Marangi)
- Add Airoha AN7583 DT compatible and driver support (Christian
Marangi)
Qualcomm PCIe controller driver:
- Add Qualcomm Kaanapali to SM8550 DT binding (Qiang Yu)
- Add required 'power-domains' and 'resets' to qcom sa8775p, sc7280,
sc8280xp, sm8150, sm8250, sm8350, sm8450, sm8550, x1e80100 DT
schemas (Krzysztof Kozlowski)
- Look up OPP using both frequency and data rate (not just frequency)
so RPMh votes can account for both (Krishna Chaitanya Chundru)
Rockchip DesignWare PCIe controller driver:
- Add Rockchip RK3528 compatible strings in DT binding (Yao Zi)
STMicroelectronics STM32MP25 PCIe controller driver:
- Fix a race between link training and endpoint register
initialization (Christian Bruel)
- Align endpoint allocations to match the ATU requirements (Christian
Bruel)
Synopsys DesignWare PCIe controller driver:
- Clear L1 PM Substate Capability 'Supported' bits unless glue driver
says it's supported, which prevents users from enabling non-working
L1SS. Currently only qcom and tegra194 support L1SS (Bjorn Helgaas)
- Remove now-superfluous L1SS disable code from tegra194 (Bjorn
Helgaas)
- Configure L1SS support in dw-rockchip when DT says
'supports-clkreq' (Shawn Lin)
TI Keystone PCIe controller driver:
- Fail the probe instead of silently succeeding if ks_pcie_of_data
didn't specify Root Complex or Endpoint mode (Siddharth Vadapalli)
- Make keystone buildable as a loadable module, except on ARM32 where
hook_fault_code() is __init (Siddharth Vadapalli)"

EFI updates for v6.19:
- Parse SMBIOS tables in memory directly on Macbooks that do not
implement the EFI SMBIOS protocol
- Obtain EDID information from the primary display while running in the
EFI stub, and expose it via bootparams on x86 (generic method is in
the works, and will likely land during the next cycle)
- Bring CPER handling for ARM systems up to data with the latest EFI
spec changes.
- Various cosmetic changes.

When interrupting perf stat in repeat mode with a signal the signal is passed to the child process but the repeat doesn't terminate: ``` $ perf stat -v --null --repeat 10 sleep 1 Control descriptor is not initialized [ perf stat: executing run #1 ... ] [ perf stat: executing run #2 ... ] ^Csleep: Interrupt [ perf stat: executing run #3 ... ] [ perf stat: executing run #4 ... ] [ perf stat: executing run #5 ... ] [ perf stat: executing run #6 ... ] [ perf stat: executing run #7 ... ] [ perf stat: executing run #8 ... ] [ perf stat: executing run #9 ... ] [ perf stat: executing run #10 ... ] Performance counter stats for 'sleep 1' (10 runs): 0.9500 +- 0.0512 seconds time elapsed ( +- 5.39% ) 0.01user 0.02system 0:09.53elapsed 0%CPU (0avgtext+0avgdata 18940maxresident)k 29944inputs+0outputs (0major+2629minor)pagefaults 0swaps ``` Terminate the repeated run and give a reasonable exit value: ``` $ perf stat -v --null --repeat 10 sleep 1 Control descriptor is not initialized [ perf stat: executing run #1 ... ] [ perf stat: executing run #2 ... ] [ perf stat: executing run #3 ... ] ^Csleep: Interrupt Performance counter stats for 'sleep 1' (10 runs): 0.680 +- 0.321 seconds time elapsed ( +- 47.16% ) Command exited with non-zero status 130 0.00user 0.01system 0:02.05elapsed 0%CPU (0avgtext+0avgdata 70688maxresident)k 0inputs+0outputs (0major+5002minor)pagefaults 0swaps ``` Note, this also changes the exit value for non-repeat runs when interrupted by a signal.

io_uring/kbuf: use READ_ONCE() for userspace-mapped memory
The struct io_uring_buf elements in a buffer ring are in a memory region accessible from userspace. A malicious/buggy userspace program could therefore write to them at any time, so they should be accessed with READ_ONCE() in the kernel. Commit |

nvmet-tcp: use kvcalloc for commands array
Replace kcalloc with kvcalloc for allocation of the commands array. Each command structure is 712 bytes. The array typically exceeds a single page, and grows much larger with high queue depths (e.g., commands >182KB). kvcalloc automatically falls back to vmalloc for large or fragmented allocations, improving reliability. In our case, this memory is not aimed for DMA operations and could be safely allocated by kvcalloc. Using virtually contiguous memory helps to avoid allocation failures and out-of-memory conditions common with kcalloc on large pools.

nvmet-rdma: use kvcalloc for commands and responses arrays
Replace kcalloc with kvcalloc for allocation of the commands and responses arrays. Each command structure is 272 bytes and each response structure is 672 bytes. These arrays typically exceed a single page, and grow much larger with high queue depths (e.g., commands >2MB, responses >170KB) kvcalloc automatically falls back to vmalloc for large or fragmented allocations, improving reliability. In our case, this memory is not aimed for DMA operations and could be safely allocated by kvcalloc. Using virtually contiguous memory helps to avoid allocation failures and out-of-memory conditions common with kcalloc on large pools.

io_uring/rsrc: fix lost entries after cloned range
When cloning with node replacements (IORING_REGISTER_DST_REPLACE),
destination entries after the cloned range are not copied over.
Add logic to copy them over to the new destination table.

nvmet-fc: use pr_* print macros instead of dev_*
Many of the nvmet-fc log messages cannot print the device used, because
it's not there yet:
(NULL device *): {0:0} Association deleted
Use the pr_* macros consistently throughout the module and match the
output of the nvme-fc module.
Using port:association ids are more useful when debugging what's going
on, because these match now with the log entries from nvme-fc.

io_uring/rsrc: rename misleading src_node variable in io_clone_buffers()
The variable holds nodes from the destination ring's existing buffer table. In io_clone_buffers(), the term "src" is used to refer to the source ring. Rename to node for clarity. Signed-off-by: Joanne Koong <joannelkoong@gmail.com> Signed-off-by: Jens Axboe <axboe@kernel.dk> |

block: fix memory leak in __blkdev_issue_zero_pages
Move the fatal signal check before bio_alloc() to prevent a memory
leak when BLKDEV_ZERO_KILLABLE is set and a fatal signal is pending.
Previously, the bio was allocated before checking for a fatal signal.
If a signal was pending, the code would break out of the loop without
freeing or chaining the just-allocated bio, causing a memory leak.
This matches the pattern already used in __blkdev_issue_write_zeroes()
where the signal check precedes the allocation.
