Add nr_guest_files in per-HART local config to represent the number of
guest files available on a particular HART whereas the nr_guest_files
in the global config represents the number of guest files available
across all HARTs.
This allows KVM RISC-V to use nr_guest_files from per-HART local
config for asymmetric big.Little systems.

The AGILEX_L3_MAIN_FREE_CLK is defined in the dt-bindings header but
was never implemented in the clock driver. Per the Agilex TRM,
l3_main_free_clk has no divider or mux and is a fixed 1:1 derivative
of noc_free_clk that clocks most of the interconnect datapath.

git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next
New feature and cleanup for Exynos fbdev
- Move fbdev emulation to DRM client buffers
. Reuses standard ADDFB2/GEM paths and simplifies cleanup.
- Use DRM format helpers for geometry and size
. Applies 4CC-based format/pitch/size calculation with stronger checks and PAGE_SIZE alignment.
. Sets screen_size and fix.smem_len from actual allocated size.
Exynos DRM internal cleanup
- Adopt DRM core DMA tracking and drop redundant code
. Removes private DMA tracking, exynos_drm_gem_prime_import(), and obsolete iommu_dma_init_domain() stub.
- Reduce duplication and tighten local scope
. Replaces MAX_FB_BUFFER with DRM_FORMAT_MAX_PLANES.
. Drops redundant exynos_drm_gem.size and internalizes local-only helpers.
Bug fix for Exynos fbdev behavior

emac_poll_rx() already runs in NAPI context and TAH-equipped EMACs set
CHECKSUM_UNNECESSARY on verified frames, which lets GRO coalesce TCP
segments without a software checksum on the merge path. Replace the
per-poll rx_list batched with netif_receive_skb_list() with direct
napi_gro_receive() calls so the stack can merge segments into super-skbs
and skip a full traversal per packet -- a meaningful win on the slow
4xx-class CPUs this driver targets.

union devlink_param_value grows substantially once U64 array
parameters are added to devlink (from 32 bytes to over 264 bytes).
devlink_nl_param_value_fill_one() and devlink_nl_param_value_put()
copy the union by value in several places. Passing two instances as
value arguments alone consumes over 528 bytes of stack; combined with
deeper call chains the parameter stack can approach 800 bytes and trip
CONFIG_FRAME_WARN more easily.
Switch internal helpers and exported driver APIs to pass pointers to
union devlink_param_value rather than passing the union by value.

Discover satellite PFs from query_esw_functions output and allocate
eswitch vports for them. For each satellite PF, create a vport via the
CREATE_ESW_VPORT command using its vhca_id and allocate it in the

When enabling switchdev mode, the ECPF acting as the eswitch manager
activates each satellite PF with enable_hca, loads its vport and adds
a representor. Since satellite PF devlink ports are registered in a
later patch, guard mlx5_esw_offloads_devlink_port() against vports
with no devlink port to avoid NULL dereference during representor

This code works, but there are a few things to tidy up:
1. No need to an unlikely() because IS_ERR() already has an unlikely()

2. No need to use PTR_ERR_OR_ZERO() because it's not an error pointer.
3. Use the returned error code directly instead of using groveling in

rvu_mbox_handler_rep_event_notify() in drivers/net/ethernet/marvell/
octeontx2/af/rvu_rep.c queues a sender-controlled REP_EVENT_NOTIFY
request body verbatim, and rvu_rep_up_notify() then forwards
event->pcifunc (the nested body field, distinct from the
AF-normalised header pcifunc) into rvu_get_pfvf(), rvu_get_pf() and
the AF->PF mailbox device index without any bounds check.
A VF attached to a PF that has been put into switchdev
representor mode reaches this path: the VF mailbox handler
otx2_pfvf_mbox_handler() forwards every message id including
MBOX_MSG_REP_EVENT_NOTIFY to AF without an allowlist, and the AF
dispatcher rewrites only msg->pcifunc, leaving struct
rep_event::pcifunc attacker-controlled. The sibling
rvu_mbox_handler_esw_cfg() refuses requests whose header pcifunc
is not rvu->rep_pcifunc; this handler has no equivalent gate.
An out-of-range body pcifunc selects an &rvu->pf[]/&rvu->hwvf[]
element past the allocated array and, for RVU_EVENT_MAC_ADDR_CHANGE,
turns into a six-byte attacker-chosen OOB ether_addr_copy() target
inside the queued worker; KASAN reports a slab-out-of-bounds write
in rvu_rep_wq_handler.
Reject malformed requests at the handler entry by gating on
is_pf_func_valid(), which is already the canonical PF/VF range check
in this driver; expose it via rvu.h so callers in rvu_rep.c can use
it instead of open-coding the same range arithmetic.

In macsec_post_decrypt(), when pn is U32_MAX, pn + 1 overflows u32 to 0
and the first branch never fires. If next_pn_halves.lower is also in the
upper half, pn_same_half(pn, lower) is true and the XPN else-if does not
fire either, leaving next_pn_halves unchanged. An attacker that captures
the legitimate frame carrying pn == 0xFFFFFFFF on an XPN association
can then replay it indefinitely, since lowest_pn never rises above
the captured pn and macsec_decrypt() reconstructs the same IV.
Extend the XPN else-if to also fire when pn + 1 wraps to 0, so receipt
of pn == U32_MAX advances next_pn_halves to (upper + 1, 0).

Remove unnecessary fields in PciRomHeader. This allows a simplification
to use `FromBytes` instead of reading fields piecemeal. A lot of these
checks were redundant as well since it checks the size of the `data`
first in `BiosImage`.

Currently, FWSEC takes the first image and the last image. Treat the
first FWSEC image and all following image data as one logical block
for building the final FWSEC image. This avoids explicitly tracking
two FWSEC images.

Add support for hardware-wrapped encryption keys to the
dm-inlinecrypt target.
Introduce a new optional argument <key_type> to indicate
whether the provided key is a raw key or a hardware-wrapped
key. Based on this flag, the appropriate blk-crypto key type
is selected when initializing the key.
This allows dm-inlinecrypt to work with hardware that requires
keys to be wrapped and managed by the underlying inline
encryption engine.
Update the target argument parsing accordingly and pass the
key type to blk_crypto_init_key(). Documentation is also
updated to reflect the new parameter and usage.

The error cleanup loop in rdma_counter_init() iterates with variable
'i' but accesses dev->port_data[port] instead of dev->port_data[i].
This causes the failed port's hstats to be freed multiple times while
leaking hstats of previously initialized ports.

When __rdma_counter_bind_qp() fails in alloc_and_bind(), the error path
jumps to err_mode which frees the counter without decrementing
port_counter->num_counters. The only place that decrements is
rdma_counter_free(), which is unreachable since the counter was never
successfully bound.
This leak accumulates across repeated failures, permanently preventing
the port from switching to AUTO mode (-EBUSY in __counter_set_mode())
and blocking the MANUAL→NONE auto-revert in rdma_counter_free(). When
the mode was NONE before the call, the MANUAL mode set by
__counter_set_mode() also leaks since the revert logic is never
reached.
Add an err_bind label between the num_counters increment and the
existing err_mode label. It decrements num_counters and mirrors the
MANUAL→NONE revert from rdma_counter_free(), ensuring the port state
is fully restored on bind failure.

Replace the open-coded resource table iteration loop in
rproc_handle_resources() with the rsc_table_for_each_entry() helper.
The remoteproc-specific dispatch logic (vendor resource handling via
rproc_handle_rsc(), RSC_LAST bounds check, handler table lookup) is
moved into a local callback rproc_handle_rsc_entry(), keeping the
iteration mechanics in one canonical place.
The callback receives the payload offset within the table so that
handlers which write back into the resource table (e.g.
rproc_handle_carveout() recording a dynamically allocated address via
rsc_offset) continue to work correctly.
No functional change.

mlx5_cmd_hws_packet_reformat_alloc() handles
MLX5_REFORMAT_TYPE_REMOVE_HDR by looking up a matching HWS remove-header
action.
If mlx5_fs_get_action_remove_header_vlan() returns NULL, the code only

HWS action stored in the packet-reformat object.
Return an error when no matching remove-header action is available.

Turn acpi_video_bus_remove_notify_handler() into a devm
action added by acpi_video_bus_probe() after calling
acpi_video_bus_add_notify_handler and use the newly introduced
devm_acpi_install_notify_handler() to install an ACPI notify

This replaces the rollback path remnant in acpi_video_bus_probe()

Use the struct device pointer to the dev member in the struct
platform_device object representing the platform device used for driver
binding as the last argument of acpi_dev_install_notify_handler() and
accordingly update acpi_pad_notify() to pass that pointer directly to
dev_name() when generating the netlink event.
Since the dev_name() value for an ACPI-enumerated platform device is the
same as the dev_name() value for the dev member of its ACPI companion
object, as per acpi_create_platform_device(), the above code modification
is not expected to cause functionality to change.
