8434c69119 pinctrl: cy8c95x0: Move driver data to the local variable in ->probe()
For all these years of driver existence the driver_data has been used
only as a raw material for other fields in the struct cy8c95x0_pinctrl.
Move it from the structure to be just a local variable in ->probe().
Later, if ever need arises, we may reconsider that.

While at it, drop an unneeded validation and replace uintptr_t with plain
unsigned long which is more readable and works in the same way.

970dacb3b9 pinctrl: cy8c95x0: remove duplicate error message
The pin control core is covered to report any error via message.
The devm_request_threaded_irq() already prints an error message.
Remove the duplicates.

While at it, drop the info message as the same information about
an IRQ in use can be retrieved differently.

b6c3af46c2 pinctrl: cy8c95x0: Don't miss reading the last bank registers
When code had been changed to use for_each_set_clump8(), it mistakenly
switched from chip->nport to chip->tpin since the cy8c9540 and cy8c9560
have a 4-pin gap. This, in particular, led to the missed read of
the last bank interrupt status register and hence missing interrupts
on those pins. Restore the upper limit in for_each_set_clump8() to take
into consideration that gap.

dd677d0598 nvmet-fcloop: Check remoteport port_state before calling done callback
In nvme_fc_handle_ls_rqst_work, the lsrsp->done callback is only set when
remoteport->port_state is FC_OBJSTATE_ONLINE.  Otherwise, the
nvme_fc_xmt_ls_rsp's LLDD call to lport->ops->xmt_ls_rsp is expected to
fail and the nvme-fc transport layer itself will directly call
nvme_fc_xmt_ls_rsp_free instead of relying on LLDD's done callback to free
the lsrsp resources.

Update the fcloop_t2h_xmt_ls_rsp routine to check remoteport->port_state.
If online, then lsrsp->done callback will free the lsrsp.  Else, return
-ENODEV to signal the nvme-fc transport to handle freeing lsrsp.

c45be7c420 Bug fixes for the IPMI driver
I apologise for this being late, I wanted to leave it in the next tree
 for a while, and the work I did came in late, but I really don't want to
 ship 7.0 with these issues.   It's been in the next tree since Feb 13,
 and I had to rebase on Feb 23 to add a missed review and to fold in a
 fix that didn't make sense by itself.
 
 This mostly revolves around getting the driver to behave when the IPMI
 device misbehaves.  Past attempts have not worked very well because I
 didn't have hardware I couldmake do this, and AI was fairly useless for
 help on this.
 
 So I modified qemu and my test suite so I could reproduce a misbehaving
 IPMI device, and with that I was able to fix the issues.

749989b2d9 sched_ext: Fix SCX_EFLAG_INITIALIZED being a no-op flag
SCX_EFLAG_INITIALIZED is the sole member of enum scx_exit_flags with no
explicit value, so the compiler assigns it 0. This makes the bitwise OR
in scx_ops_init() a no-op:

    sch->exit_info->flags |= SCX_EFLAG_INITIALIZED; /* |= 0 */

As a result, BPF schedulers cannot distinguish whether ops.init()
completed successfully by inspecting exit_info->flags.

Assign the value 1LLU << 0 so the flag is actually set.

4226479f91 drm/i915/dpt: pass opaque struct intel_dpt around instead of i915_address_space
struct i915_address_space is used in an opaque fashion in the display
parent interface, but it's just one include away from being
non-opaque. And anyway the name is rather specific.

Switch to using the struct intel_dpt instead, which embeds struct
i915_address_space anyway. With the definition hidden in i915_dpt.c,
this can't be accidentally made non-opaque, and the type seems rather
more generic anyway.

We do have to add a new helper i915_dpt_to_vm(), as there's one case in
intel_fb_pin_to_dpt() that requires direct access to struct
i915_address_space. But this just underlines the point about opacity.

The functions ath11k_mac_setup_bcn_tmpl_ema() and
ath11k_mac_setup_bcn_tmpl_mbssid() allocate memory for beacon templates
but fail to free it when parameter setup returns an error.

Since beacon templates must be released during normal execution, they
must also be released in the error handling paths to prevent memory
leaks.

Fix this by using unified exit paths with proper cleanup in the respective
error paths.

Compile tested only. Issue found using a prototype static analysis tool
and code review.

151322bccd wifi: ath12k: add basic hwmon temperature reporting
Add initial thermal support by wiring up a per-radio (pdev) hwmon temperature
sensor backed by the existing WMI pdev temperature command and event.
When userspace reads the sysfs file temp1_input, the driver sends
WMI_PDEV_GET_TEMPERATURE_CMDID (tag WMI_TAG_PDEV_GET_TEMPERATURE_CMD) and waits
for the corresponding WMI_PDEV_TEMPERATURE_EVENTID
(tag WMI_TAG_PDEV_TEMPERATURE_EVENT) to get the temperature and pdev_id.

Export the reported value in millidegrees Celsius as required by hwmon.
The temperature reported is per-radio (pdev). In a multi-radio wiphy under a
single phy, a separate hwmon device is created for each radio.

Sample command and output:
$ cat /sys/devices/pci0000:00/.../ieee80211/phyX/hwmonY/temp1_input

b7bf516c3e bpf: Fix stack-out-of-bounds write in devmap
get_upper_ifindexes() iterates over all upper devices and writes their
indices into an array without checking bounds.

Also the callers assume that the max number of upper devices is
MAX_NEST_DEV and allocate excluded_devices[1+MAX_NEST_DEV] on the stack,
but that assumption is not correct and the number of upper devices could
be larger than MAX_NEST_DEV (e.g., many macvlans), causing a
stack-out-of-bounds write.

Add a max parameter to get_upper_ifindexes() to avoid the issue.
When there are too many upper devices, return -EOVERFLOW and abort the
redirect.

To reproduce, create more than MAX_NEST_DEV(8) macvlans on a device with
an XDP program attached using BPF_F_BROADCAST | BPF_F_EXCLUDE_INGRESS.
Then send a packet to the device to trigger the XDP redirect path.

ef06fd16d4 bpf, arm64: Force 8-byte alignment for JIT buffer to prevent atomic tearing
struct bpf_plt contains a u64 target field. Currently, the BPF JIT
allocator requests an alignment of 4 bytes (sizeof(u32)) for the JIT
buffer.

Because the base address of the JIT buffer can be 4-byte aligned (e.g.,
ending in 0x4 or 0xc), the relative padding logic in build_plt() fails
to ensure that target lands on an 8-byte boundary.

This leads to two issues:
1. UBSAN reports misaligned-access warnings when dereferencing the
   structure.
2. More critically, target is updated concurrently via WRITE_ONCE() in
   bpf_arch_text_poke() while the JIT'd code executes ldr. On arm64,
   64-bit loads/stores are only guaranteed to be single-copy atomic if
   they are 64-bit aligned. A misaligned target risks a torn read,
   causing the JIT to jump to a corrupted address.

Fix this by increasing the allocation alignment requirement to 8 bytes
(sizeof(u64)) in bpf_jit_binary_pack_alloc(). This anchors the base of
the JIT buffer to an 8-byte boundary, allowing the relative padding math
in build_plt() to correctly align the target field.

ASoC: SDCA: Improve mapping of Q7.8 SDCA volumes
SDCA measures volumes in 256ths of a dB, whereas ALSA measures
volumes in 100ths of a dB. Currently the SDCA volume controls are
mapped to ALSA controls by mapping the step size and working out
the number of steps for this mapped step size. Due to quantization
of the step size this means the number of steps in the ALSA
control will rarely match the number of steps in the SDCA control,
leading to skipped values and multiple values that map to the
same volume. This is not a huge problem, the volume is still
increasing and the differences will be small but it is not really
desirable.

It is simpler and more accurate to count the number of steps based on
the SDCA volume levels. This gives a 1-to-1 mapping between control
values and register volumes. The TLV is based on a minimum and maximum
volume so still accurately specifies the volume range.

ASoC: SDCA: Update counting of SU/GE DAPM routes
Device Layer Selector Unit's are controlled by a Group Entity control
rather than by the host directly. For the purposes of the ASoC class
driver the number of input routes to the SU is controlled by the number
of options within the Group Entity Selected Mode Control. ie. One valid
DAPM route for each valid route defined in the Group Entity.

Currently the code assumes that a Device Layer SU will have a number of
routes equal to the number of potential sources for the SU. ie. it
counts the routes using the SU, but then creates the routes using the
GE. However, this isn't actually true, it is perfectly allowed for the
GE to only define options for some of the potential sources of the SU.o
In such a case the number of routes return will not match those created,
leading to either an overflow of the routes array or undefined routes to
be past to the ASoC core, both of which generally lead to the sound card
failing to probe.

Update the handling for the counting of routes to count the connected
routes on the GE itself and then ignore the source routes on the SU.
This makes it match the logic generating the routes and ensuring that
both remain in sync.

of clang that supports btf_type_tag.

genksyms falls over parsing the __rcu attribute in the declarator:

  # Kernel reproducer
  $ make -skj"$(nproc)" ARCH=x86_64 KCFLAGS=-D__GENKSYMS__ LLVM=1 net/netfilter/nf_conntrack_ftp.i

  $ scripts/genksyms/genksyms -w <net/netfilter/nf_conntrack_ftp.i &| rg 'syntax error'

  net/netfilter/nf_conntrack_ftp.c:46: syntax error

  # Trivial reproducer
  $ cat test.c
  int (*func)(void *foo, int bar);
  int (__attribute__((btf_type_tag("rcu"))) *func_with_attr)(void *foo, int bar);

  $ scripts/genksyms/genksyms -w <test.c
  <stdin>:2: syntax error

Optionally allow an attribute to precede a declarator to resolve this
error and properly generate symbol versions.

kbuild: Split .modinfo out from ELF_DETAILS
Commit 3e86e4d74c ("kbuild: keep .modinfo section in
vmlinux.unstripped") added .modinfo to ELF_DETAILS while removing it
from COMMON_DISCARDS, as it was needed in vmlinux.unstripped and
ELF_DETAILS was present in all architecture specific vmlinux linker
scripts. While this shuffle is fine for vmlinux, ELF_DETAILS and
COMMON_DISCARDS may be used by other linker scripts, such as the s390
and x86 compressed boot images, which may not expect to have a .modinfo
section. In certain circumstances, this could result in a bootloader
failing to load the compressed kernel [1].

Commit ddc6cbef3e ("s390/boot/vmlinux.lds.S: Ensure bzImage ends with
SecureBoot trailer") recently addressed this for the s390 bzImage but
the same bug remains for arm, parisc, and x86. The presence of .modinfo
in the x86 bzImage was the root cause of the issue worked around with
commit d50f210913 ("kbuild: align modinfo section for Secureboot
Authenticode EDK2 compat"). misc.c in arch/x86/boot/compressed includes
lib/decompress_unzstd.c, which in turn includes lib/xxhash.c and its
MODULE_LICENSE / MODULE_DESCRIPTION macros due to the STATIC definition.

Split .modinfo out from ELF_DETAILS into its own macro and handle it in
all vmlinux linker scripts. Discard .modinfo in the places where it was
previously being discarded from being in COMMON_DISCARDS, as it has
never been necessary in those uses.
