First of all, we don't use intel-family.h directly. On the other hand
we actively use boolean type, that is defined in the types.h (we take
top-level header for that) and x86_cpu_id, that is provided in the
mod_devicetable.h.
Secondly, we don't need to spread SOC_INTEL_IS_CPU() macro to the users.
Hence, undefine it when it's appropriate.

There is one Intel Out-of-Band (OOB) PCI device per CPU package. Since
TPMI feature is exposed via OOB PCI device, there will be multiple
TPMI device instances on a multi CPU package system.
There are several PM features, which needs to associate APIC based CPU
package ID information to a TPMI instance. For example if Intel Speed
Select feature requires control of a CPU package, it needs to identify
right TPMI device instance.
There is one special TPMI ID (ID = 0x81) in the PFS. The MMIO
region of this TPMI ID points to a mapping table:
- PCI Bus ID
- PCI Device ID
- APIC based Package ID
This mapping information can be used by any PM feature driver which
requires mapping from a CPU package to a TPMI device instance.
Unlike other TPMI features, device node is not created for this feature
ID (0x81). Instead store the mapping information as platform data, which
is part of the per PCI device TPMI instance (struct intel_tpmi_info).
Later the TPMI feature drivers can get the mapping information using an
interface "tpmi_get_platform_data()"

Make v4l2_async_register_subdev_sensor() try to get a privacy LED
associated with the sensor and extend the call_s_stream() wrapper to
enable/disable the privacy LED if found.
This makes the core handle privacy LED control, rather then having to
duplicate this code in all the sensor drivers.

Merge tag 'ib-leds-led_get-v6.3' into HEAD
Immutable branch from LEDs due for the v6.3 merge window
We currently have a struct ssam_request_sync and a function
ssam_request_sync(). While this is valid C, there are some downsides to
it.
One of these is that current Sphinx versions (>= 3.0) cannot
disambiguate between the two (see disucssion and pull request linked
below). It instead emits a "WARNING: Duplicate C declaration" and links
for the struct and function in the resulting documentation link to the
same entry (i.e. both to either function or struct documentation)
instead of their respective own entries.
While we could just ignore that and wait for a fix, there's also a point
to be made that the current naming can be somewhat confusing when
searching (e.g. via grep) or trying to understand the levels of
abstraction at play:
We currently have struct ssam_request_sync and associated functions
ssam_request_sync_[alloc|free|init|wait|...]() operating on this struct.
However, function ssam_request_sync() is one abstraction level above
this. Similarly, ssam_request_sync_with_buffer() is not a function
operating on struct ssam_request_sync, but rather a sibling to
ssam_request_sync(), both using the struct under the hood.
Therefore, rename the top level request functions:
ssam_request_sync() -> ssam_request_do_sync()
ssam_request_sync_with_buffer() -> ssam_request_do_sync_with_buffer()
ssam_request_sync_onstack() -> ssam_request_do_sync_onstack()

Similar to the target category (TC), the target ID (TID) can be one
value out of a small number of choices, given in enum ssam_ssh_tid.
In the device ID macros, SSAM_SDEV() and SSAM_VDEV() we already use text
expansion to, both, remove some textual clutter for the target category
values and enforce that the value belongs to the known set. Now that we
know the names for the target IDs, use the same trick for them as well.
Also rename the SSAM_ANY_x macros to SSAM_SSH_x_ANY to better fit in.

The `tid_in` and `tid_out` fields of the serial hub protocol command
struct (struct ssh_command) are actually source and target IDs,
indicating the peer from which the message originated and the peer for
which it is intended.
Change the naming of those fields accordingly and improve the protocol
documentation. Additionally, introduce an enum containing all currently

Add a generic [devm_]led_get() method which can be used on both devicetree
and non devicetree platforms to get a LED classdev associated with
a specific function on a specific device, e.g. the privacy LED associated
with a specific camera sensor.
Note unlike of_led_get() this takes a string describing the function
rather then an index. This is done because e.g. camera sensors might
have a privacy LED, or a flash LED, or both and using an index
approach leaves it unclear what the function of index 0 is if there is
only 1 LED.
This uses a lookup-table mechanism for non devicetree platforms.
This allows the platform code to map specific LED class_dev-s to a specific
device,function combinations this way.
For devicetree platforms getting the LED by function-name could be made
to work using the standard devicetree pattern of adding a -names string
array to map names to the indexes.

The struct device driver-data pointer is used for any data that a driver
may need in various callbacks while bound to the device. For
convenience, subsystems typically provide wrappers such as
usb_set_intfdata() of the generic accessor functions for use in bus
callbacks.
There is generally no longer any need for a driver to clear the pointer,
but since commit 0998d06310 ("device-core: Ensure drvdata = NULL when
no driver is bound") the driver-data pointer is set to NULL by driver
core post unbind anyway.
For historical reasons, USB core also clears this pointer when an
explicitly claimed interface is released.
Due to a misunderstanding, a misleading kernel doc comment for
usb_set_intfdata() was recently added which claimed that the driver data
pointer must not be cleared during disconnect before "all actions [are]
completed", which is both imprecise and incorrect.
Specifically, drivers like cdc-acm which claim additional interfaces use
the driver-data pointer as a flag which is cleared when the first
interface is unbound. As long as a driver does not do something odd like
dereference the pointer in, for example, completion callbacks, this can
be done at any time during disconnect. And in any case this is no
different than for any other resource, like the driver data itself,
which may be freed by the disconnect callback.
Note that the comment actually also claimed that the interface itself
was somehow being set to NULL by driver core.
Fix the kernel doc by removing incorrect, overly specific and misleading
details and adding a comment about why some drivers do clear the
driver-data pointer.

Add a helper to evaluate ACPI usb device specific method (_DSM) provided
in case the USB3 port shouldn't enter U1 and U2 link states.
This _DSM was added as port specific retimer configuration may lead to
exit latencies growing beyond U1/U2 exit limits, and OS needs a way to
find which ports can't support U1/U2 link power management states.
This _DSM is also used by windows:

syzbot reported a nasty crash [1] in net_tx_action() which
made little sense until we got a repro.
This repro installs a taprio qdisc, but providing an
invalid TCA_RATE attribute.
qdisc_create() has to destroy the just initialized
taprio qdisc, and taprio_destroy() is called.
However, the hrtimer used by taprio had already fired,
therefore advance_sched() called __netif_schedule().
Then net_tx_action was trying to use a destroyed qdisc.
We can not undo the __netif_schedule(), so we must wait
until one cpu serviced the qdisc before we can proceed.
Many thanks to Alexander Potapenko for his help.

- avoid a potential crash on the efi_subsys_init() error path
- use more appropriate error code for runtime services calls issued

efi: tpm: Avoid READ_ONCE() for accessing the event log
efi: rt-wrapper: Add missing include
efi: fix userspace infinite retry read efivars after EFI runtime services page fault
efi: fix NULL-deref in init error path
Nathan reports that recent kernels built with LTO will crash when doing
EFI boot using Fedora's GRUB and SHIM. The culprit turns out to be a
misaligned load from the TPM event log, which is annotated with
READ_ONCE(), and under LTO, this gets translated into a LDAR instruction
which does not tolerate misaligned accesses.
Interestingly, this does not happen when booting the same kernel
straight from the UEFI shell, and so the fact that the event log may
appear misaligned in memory may be caused by a bug in GRUB or SHIM.
However, using READ_ONCE() to access firmware tables is slightly unusual
in any case, and here, we only need to ensure that 'event' is not
dereferenced again after it gets unmapped, but this is already taken
care of by the implicit barrier() semantics of the early_memunmap()
call.

Pull arm64 fixes from Will Deacon:
"Here's a sizeable batch of Friday the 13th arm64 fixes for -rc4. What
could possibly go wrong?
The obvious reason we have so much here is because of the holiday
season right after the merge window, but we've also brought back an
erratum workaround that was previously dropped at the last minute and
there's an MTE coredumping fix that strays outside of the arch/arm64
directory.
Summary:
- Fix PAGE_TABLE_CHECK failures on hugepage splitting path
- Fix PSCI encoding of MEM_PROTECT_RANGE function in UAPI header
- Fix NULL deref when accessing debugfs node if PSCI is not present
- Fix MTE core dumping when VMA list is being updated concurrently
- Fix SME signal frame handling when SVE is not implemented by the
CPU
- Fix asm constraints for cmpxchg_double() to hazard both words
- Fix build failure with stack tracer and older versions of Clang
- Bring back workaround for Cortex-A715 erratum 2645198"

Commit 449c796768 ("mm: teach release_pages() to take an array of
encoded page pointers too") added the kernel doc comment for
release_pages() on top of 'union release_pages_arg', so making 'make
htmldocs' complains as below:
./include/linux/mm.h:1268: warning: cannot understand function prototype: 'typedef union '
The kernel doc comment for the function is already on top of the
function's definition in mm/swap.c, and the new comment is actually not
for the function but indeed release_pages_arg. Fixing the comment to
reflect the intent would be one option. But, kernel doc cannot parse
the union as below due to the attribute.
./include/linux/mm.h:1272: error: Cannot parse struct or union!
Modify the comment to reflect the intent but do not mark it as a kernel
doc comment.

ARM: SoC fixes
These are three fixes for mistakes I discovered during the preparation
of the boardfile removal. Robert noticed the accidental removal
of PXA310 and PXA320 support because of a misplaced Kconfig statement,
and the two OMAP patches were build failures that got introduced
earlier but that I found while testing the removal.
* 'armsoc-build-fixes' of https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc:
ARM: omap1: fix building gpio15xx
ARM: omap1: fix !ARCH_OMAP1_ANY link failures
ARM: pxa: enable PXA310/PXA320 for DT-only build
While compile-testing randconfig builds for the upcoming boardfile
removal, I noticed that an earlier patch of mine was completely
broken, and the introduction of CONFIG_ARCH_OMAP1_ANY only replaced
one set of build failures with another one, now resulting in
link failures like
ld: drivers/video/fbdev/omap/omapfb_main.o: in function `omapfb_do_probe':
drivers/video/fbdev/omap/omapfb_main.c:1703: undefined reference to `omap_set_dma_priority'
ld: drivers/dma/ti/omap-dma.o: in function `omap_dma_free_chan_resources':
drivers/dma/ti/omap-dma.c:777: undefined reference to `omap_free_dma'
drivers/dma/ti/omap-dma.c:1685: undefined reference to `omap_get_plat_info'
ld: drivers/usb/gadget/udc/omap_udc.o: in function `next_in_dma':
drivers/usb/gadget/udc/omap_udc.c:820: undefined reference to `omap_get_dma_active_status'
I tried reworking it, but the resulting patch ended up much bigger than
simply avoiding the original problem of unused-function warnings like
arch/arm/mach-omap1/mcbsp.c:76:30: error: unused variable 'omap1_mcbsp_ops' [-Werror,-Wunused-variable]
As a result, revert the previous fix, and rearrange the code that
produces warnings to hide them. For mcbsp, the #ifdef check can
simply be removed as the cpu_is_omapxxx() checks already achieve
the same result, while in the io.c the easiest solution appears to
be to merge the common map bits into each soc specific portion.
This gets cleaned in a nicer way after omap7xx support gets dropped,
as the remaining SoCs all have the exact same I/O map.

The Dell Latitude E6430 both with and without the optional NVidia dGPU
has a bug in its ACPI tables which is causing Linux to assign the wrong
ACPI fwnode / companion to the pci_device for the i915 iGPU.
Specifically under the PCI root bridge there are these 2 ACPI Device()s :
Scope (_SB.PCI0)
{
Device (GFX0)
{
Name (_ADR, 0x00020000) // _ADR: Address
}
...
Device (VID)
{
Name (_ADR, 0x00020000) // _ADR: Address
...
Method (_DOS, 1, NotSerialized) // _DOS: Disable Output Switching
{
VDP8 = Arg0
VDP1 (One, VDP8)
}
Method (_DOD, 0, NotSerialized) // _DOD: Display Output Devices
{
...
}
...
}
}
The non-functional GFX0 ACPI device is a problem, because this gets
returned as ACPI companion-device by acpi_find_child_device() for the iGPU.
This is a long standing problem and the i915 driver does use the ACPI
companion for some things, but works fine without it.
However since commit 63f534b8ba ("ACPI: PCI: Rework acpi_get_pci_dev()")
acpi_get_pci_dev() relies on the physical-node pointer in the acpi_device
and that is set on the wrong acpi_device because of the wrong
acpi_find_child_device() return. This breaks the ACPI video code,
leading to non working backlight control in some cases.
Add a type.backlight flag, mark ACPI video bus devices with this and make
find_child_checks() return a higher score for children with this flag set,
so that it picks the right companion-device.

When a running wake_tx_queue() call is aborted due to a hw queue stop
the corresponding iTXQ is not always correctly marked for resumption:
wake_tx_push_queue() can stops the queue run without setting
@IEEE80211_TXQ_STOP_NETIF_TX.
Without the @IEEE80211_TXQ_STOP_NETIF_TX flag __ieee80211_wake_txqs()
will not schedule a new queue run and remaining frames in the queue get
stuck till another frame is queued to it.
Fix the issue for all drivers - also the ones with custom wake_tx_queue
callbacks - by moving the logic into ieee80211_tx_dequeue() and drop the
redundant @txqs_stopped.
@IEEE80211_TXQ_STOP_NETIF_TX is also renamed to @IEEE80211_TXQ_DIRTY to
better describe the flag.

Move the connection setup of client calls to the I/O thread so that a whole
load of locking and barrierage can be eliminated. This necessitates the
app thread waiting for connection to complete before it can begin
encrypting data.
This also completes the fix for a race that exists between call connection
and call disconnection whereby the data transmission code adds the call to
the peer error distribution list after the call has been disconnected (say
by the rxrpc socket getting closed).
The fix is to complete the process of moving call connection, data
transmission and call disconnection into the I/O thread and thus forcibly
serialising them.
Note that the issue may predate the overhaul to an I/O thread model that
were included in the merge window for v6.2, but the timing is very much
changed by the change given below.
