Pin the user CQ buffer with ib_umem_get_cq_buf() and take
ownership of the umem in the driver; fall back to
ib_umem_get_va() for the legacy UHW VA path. Apply the same
ownership pattern to the resize path.

Add UVERBS_ATTR_CREATE_CQ_BUF_UMEM and two driver-facing
wrappers, ib_umem_get_cq_buf() and ib_umem_get_cq_buf_or_va(),
that pin a CQ buffer umem from it. The wrappers reuse the
existing legacy CQ buffer-attr filler.

Extract the UVERBS_ATTR_CREATE_CQ_BUFFER_* parser from the CQ
create handler into uverbs_create_cq_get_buffer_desc(), and wrap
it in ib_umem_get_cq_tmp(), the umem-producing helper the cq_create
handler now calls.
ib_umem_get_cq_tmp() is temporary; subsequent patches replace it
with driver-owned ib_umem_get_cq_buf*() wrappers built on the
same parser, and remove it once all CQ drivers have switched.

ib_umem_get_va() is now redundant: ib_umem_get_attr_or_va() with
attrs=NULL and attr_id=0 covers the exact same path. Make it a static

Introduce a per-attribute UVERBS_ATTR_UMEM model so each uverbs
command's umem set is explicit in its UAPI definition. Add
driver-facing wrapper helpers that pin a umem on demand from an
attribute or a VA addr; the driver owns the returned umem and
releases it from its destroy/error paths.

The follow-up patch is going to introduce ib_umem_get_desc(),
the canonical desc-to-umem helper, which needs to pin a userspace VA
without going through the exported ib_umem_get_va() helper so later on
ib_umem_get_va() would use the ib_umem_get_desc() flow too.
Move the existing ib_umem_get_va() to a static __ib_umem_get_va()
and have ib_umem_get_va() as a thin wrapper that calls it.

The new umem getter family being introduced in follow-up patches
need a fitting name for the central all-source helper that resolves
attributes, legacy fillers and a UHW VA fallback.
Rename the existing VA-pinning helper ib_umem_get() to ib_umem_get_va()
so the name is freed up. The new name is consistent with names of rest
of the helpers that are about to be introduced.

Arm FF-A + SMCCC updates for v7.2
1. The FF-A core is moved onto the driver model by reverting the earlier
rootfs initcall change and registering the core as a platform driver with
a synthetic arm-ffa platform device. Enumerated FF-A devices are now
parented below the FF-A core device, and probing is deferred until pKVM
has completed its FF-A proxy initialisation.
2. The platform-driver conversion is also adjusted so systems without FF-A
support treat early unsupported transport/version discovery as a quiet
probe miss rather than a failed matched probe.
3. The register-based partition discovery path now honors the descriptor
size reported by FFA_PARTITION_INFO_GET_REGS. This keeps parsing aligned
for newer FF-A descriptor layouts while still copying only the fields the
driver understands.
4. Also included is an Arm SMCCC fix for the optional SOC_ID name call: the
name query now uses the SMC64 function ID required for returning eight
characters per register.

This reverts commit 3812a9e84265a5cdd90d29fe8d97a023e91fb945.
The probe ordering fix in the following patch ensures amd_gpio_probe()
completes before i2c-designware probes AMDI0010:02, allowing the
existing amd_gpio_irq_enable() flow to work correctly. The manual IRQ
restoration added by this patch is therefore no longer needed.

drm_gem_change_handle_ioctl leaves the old handle live in the IDR
during the window between spin_unlock(table_lock) and the final
spin_lock(table_lock). A concurrent drm_gem_handle_delete on the old
handle succeeds in this window, decrements handle_count to 0, and frees
the GEM object while the new handle's IDR entry still references it.
NULL the old handle's IDR entry before dropping table_lock so that any
concurrent GEM_CLOSE on the old handle sees NULL and returns -EINVAL.
Restore the old entry on the prime-bookkeeping error path.

Before commit 14dbe186b9d4 ("pinctrl: msmgpio: Make the irqchip immutable")
msm gpio irqchip conditionally initialized pctrl->irq_chip.irq_eoi to
irq_chip_eoi_parent() only for the GPIO irqs having a wakeup capable irq.
In order to make gpio irqchip immutable pctrl->irq_chip.irq_eoi is
initialized to msm_gpio_irq_eoi() which now gets invoked for both wake up
and non-wakeup capable GPIO IRQs.
Replace open coded eoi call to parent irqchip with irq_chip_eoi_parent().
Since the irq_chip_*_parent() APIs internally do not check the valid parent
data is present to ensure irq_chip_eoi_parent() is only invoked for wakeup
capable GPIOs validate d->parent_data within msm_gpio_irq_eoi().
For non wakeup capable GPIOs d->parent_data will be NULL since parent
irqchip diconnects hierarchy using irq_domain_disconnect_hierarchy() and
later irq framework trims hierarchy using irq_domain_trim_hierarchy() which
makes d->parent_data as NULL.
No functional impact.

... and PCI device helpers.
The various struct pci_device_id arrays were initialized mostly by one of the
PCI_DEVICE macros and then list expressions. The latter aren't easily readable
if you're not into PCI. Using named initializers is more explicit and thus
easier to parse.
Also use PCI_DEVICE* helper macros to assign .vendor, .device, .subvendor and
.subdevice where appropriate and skip explicit assignments of 0 (which the
compiler takes care of).
The secret plan is to make struct pci_device_id::driver_data an anonymous
union (similar to
https://lore.kernel.org/all/cover.1776579304.git.u.kleine-koenig@baylibre.com/

With how this is currently written, we add the trailer, zero it out, and
then add the header space on. If that header space requires a
reallocation + copy, the zeros in the trailer aren't copied, because the
skb len hasn't actually been yet expanded to cover that. Instead add the
padding at the end of the process rather than at the beginning.

The DRIVER_GEM_GPUVA feature flag is currently only used to control two
behaviors within the DRM core:
- calling drm_gem_gpuva_init() during
GEM object initialization
- creating the "gpuvas" debugfs entry
drm_gem_gpuva_init() is a plain INIT_LIST_HEAD() and therefore is cheap
to run for every GEM object. The DRM_DEBUGFS_GPUVA_INFO macro is only
referenced by GPU-VA capable drivers, so clearing the feature bit does
not cause any unrelated drivers to get the "gpuvas" debugfs node. The
flag doesn't have any relevant purpose (e.g. gating ioctl handlers or MM
logic) and doesn't provide any practical benefit.
Remove the flag definition and drop it from all drivers that use it,
call drm_gem_gpuva_init() unconditionally and clear the driver features
bit in DRM_DEBUGFS_GPUVA_INFO.

patch that will move RRL(retry_rd_err_log) code from i10nm_basic.c to

If error reporting is enabled during initialization but initialization
fails immediately after, or during normal driver teardown, error reporting
is left enabled in the mask register even after exit.
Replace i5400_enable_error_reporting() with i5400_set_error_reporting()
to combine enabling/disabling. Disable reporting at initialization
failure and driver exit, before call to i5400_put_devices() for cleanup.
This ensures clean hardware handling by disabling any unused error
reporting bits before exiting.
