Many of the possible pincfg properties are not compatible with one
another, either because they represent mutually exclusive states for a
pin or because they provide the same information in different units.
Add some simple restrictions to prevent invalid configurations.

Some pinconf properties are mutually exclusive, either because they
convey the same information in different units or represent incompatible
configurations of the same pin. Attempt, in two ways, to prevent these
situations.
Firstly, for enable/disable properties, produce an error if both are
set. Since enable/disable properties share the same enum value, they can
be trivially checked via the newly added bitmap. Having both enable and
disable for the same config makes no sense at all, so produce an error
in this case.
For interactions between properties, doing them outside the loop makes
more sense as it can be evaluated once. In case there are some edge
cases that would be broken by producing an error, only warn for now.

When mounting a share with 'multichannel,max_channels=n,sec=krb5i',
the client was duplicating signing key for all secondary channels,
thus making the server fail all commands sent from secondary channels
due to bad signatures.
Every channel has its own signing key, so when establishing a new
channel with krb5 auth, make sure to use the new session key as the
derived key to generate channel's signing key in SMB2_auth_kerberos().
Repro:
$ mount.cifs //srv/share /mnt -o multichannel,max_channels=4,sec=krb5i
$ sleep 5
$ umount /mnt

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.

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.

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.

Pull IPMI driver fixes from Corey Minyard:
"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 could make 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"

ctx_restore_mid_bb memory is allocated in wa_bb_store(), but
xe_config_device_release() only frees ctx_restore_post_bb.
Free ctx_restore_mid_bb[0].cs as well to avoid leaking the allocation
when the configfs device is removed.

Somehow people got into the habit of putting labels at the tops of
documentation files, even when they are not used. It is better to just
give the name of a file when linking to the whole thing; remove the label
and update the references accordingly.

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.

When CONFIG_DEBUG_INFO_BTF_MODULES is enabled and vmlinux is available,
Makefile.modfinal and gen-btf.sh will try to use resolve_btfids on the
module .ko. install-extmod-build currently does not package
resolve_btfids, so that step fails.
Package resolve_btfids if it may be used.

Merge series from Svyatoslav Ryhel <clamor95@gmail.com>:
The initial goal was only to add support for the CPCAP used in the Mot
Tegra20 board; however, since the documentation was already partially
converted, I decided to complete the conversion to schema too.
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.

Rename struct i915_dpt to intel_dpt. This may seem rather inconsistent
considering we just renamed the functions the other way round, but the
intent here is to lift struct intel_dpt to the display parent interface
as the generic opaque type for DPT instead of the very specific struct
i915_address_space.

The remaining functions declared in intel_dpt.h are i915 specific, and
so are the users, so we can move them to i915_dpt.h. There are some
useless intel_dpt.h includes around that we can remove.

Split the size determination between caller and callee to drop the
dependency on struct intel_framebuffer from DPT code, but avoid adding a
dependency on I915_GTT_PAGE_SIZE in the caller side.
Pass zero size to let intel_dpt_create() handle the regular obj->size
case, but remapped size if fb needs stride remap.

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.

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
$ 50000
