More Qualcomm driver updates for 5.13
This improves the Qualcomm SCM driver logic related to detecting the
calling convention, in particular on SC7180, and fixes a few small
issues in the same.
It introduces additonal sanity checks of the size of loaded segments in
the MDT loader and adds a missing error in the return path of
pdr_register_listener().
It makes it possible to specify the OEM specific firmware path in the
wcn36xx control (and WiFi) driver.
Lastly it adds a missing path specifier in the MAINTAINERS' entry and
fixes a bunch of kerneldoc issues in various drivers.

This can be used by Type-C controller drivers which use a standard
usb-connector fwnode, with altmodes sub-node, to describe the available
altmodes.
Note there are is no devicetree bindings documentation for the altmodes
node, this is deliberate. ATM the fwnodes used to register the altmodes
are only used internally to pass platform info from a drivers/platform/x86
driver to the type-c subsystem.
When a devicetree user of this functionally comes up and the dt-bindings
have been hashed out the internal use can be adjusted to match the
dt-bindings.
Currently the typec_port_register_altmodes() function expects
an "altmodes" child fwnode on port->dev with this "altmodes" fwnode having
child fwnodes itself with each child containing 2 integer properties:
1. A "svid" property, which sets the id of the altmode, e.g. displayport
altmode has a svid of 0xff01.
2. A "vdo" property, typically used as a bitmask describing the
capabilities of the altmode, the bits in the vdo are specified in the
specification of the altmode.

Given that lowlevel drivers usually cannot implement exactly what a
consumer requests with pwm_apply_state() there is some rounding

pwm_get_state() returns the setting that was requested most recently by
the consumer (opposed to what was actually implemented in hardware in

static_call_update() had stronger type requirements than regular C,
relax them to match. Instead of requiring the @func argument has the
exact matching type, allow any type which C is willing to promote to the
right (function) pointer type. Specifically this allows (void *)
arguments.
This cleans up a bunch of static_call_update() callers for
PREEMPT_DYNAMIC and should get around silly GCC11 warnings for free.

Previous kernels allowed the BLKROSET to override the disk's read-only
status. With that situation fixed the pmem driver needs to rely on
notification events to reevaluate the disk read-only status after the
host region has been marked read-write.
Recall that when libnvdimm determines that the persistent memory has
lost persistence (for example lack of energy to flush from DRAM to FLASH
on an NVDIMM-N device) it marks the region read-only, but that state can
be overridden by the user via:
echo 0 > /sys/bus/nd/devices/regionX/read_only
...to date there is no notification that the region has restored
persistence, so the user override is the only recovery.

list_sort() internally casts the comparison function passed to it
to a different type with constant struct list_head pointers, and
uses this pointer to call the functions, which trips indirect call
Control-Flow Integrity (CFI) checking.
Instead of removing the consts, this change defines the
list_cmp_func_t type and changes the comparison function types of
all list_sort() callers to use const pointers, thus avoiding type
mismatches.

With CONFIG_CFI_CLANG, the compiler replaces function addresses
in instrumented C code with jump table addresses. This means that
__pa_symbol(function) returns the physical address of the jump table
entry instead of the actual function, which may not work as the jump
table code will immediately jump to a virtual address that may not be
mapped.
To avoid this address space confusion, this change adds a generic
definition for function_nocfi(), which architectures that support CFI
can override. The typical implementation of would use inline assembly
to take the function address, which avoids compiler instrumentation.

With CONFIG_CFI_CLANG, the compiler replaces a function address taken
in C code with the address of a local jump table entry, which passes
runtime indirect call checks. However, the compiler won't replace
addresses taken in assembly code, which will result in a CFI failure
if we later jump to such an address in instrumented C code. The code
generated for the non-canonical jump table looks this:
<noncanonical.cfi_jt>: /* In C, &noncanonical points here */
jmp noncanonical
...
<noncanonical>: /* function body */
...
This change adds the __cficanonical attribute, which tells the
compiler to use a canonical jump table for the function instead. This
means the compiler will rename the actual function to <function>.cfi
and points the original symbol to the jump table entry instead:
<canonical>: /* jump table entry */
jmp canonical.cfi
...
<canonical.cfi>: /* function body */
...
As a result, the address taken in assembly, or other non-instrumented
code always points to the jump table and therefore, can be used for
indirect calls in instrumented code without tripping CFI checks.

This change adds support for Clang’s forward-edge Control Flow
Integrity (CFI) checking. With CONFIG_CFI_CLANG, the compiler
injects a runtime check before each indirect function call to ensure
the target is a valid function with the correct static type. This
restricts possible call targets and makes it more difficult for
an attacker to exploit bugs that allow the modification of stored
function pointers. For more details, see:
https://clang.llvm.org/docs/ControlFlowIntegrity.html
Clang requires CONFIG_LTO_CLANG to be enabled with CFI to gain
visibility to possible call targets. Kernel modules are supported
with Clang’s cross-DSO CFI mode, which allows checking between
independently compiled components.
With CFI enabled, the compiler injects a __cfi_check() function into
the kernel and each module for validating local call targets. For
cross-module calls that cannot be validated locally, the compiler
calls the global __cfi_slowpath_diag() function, which determines
the target module and calls the correct __cfi_check() function. This
patch includes a slowpath implementation that uses __module_address()
to resolve call targets, and with CONFIG_CFI_CLANG_SHADOW enabled, a
shadow map that speeds up module look-ups by ~3x.
Clang implements indirect call checking using jump tables and
offers two methods of generating them. With canonical jump tables,
the compiler renames each address-taken function to <function>.cfi
and points the original symbol to a jump table entry, which passes
__cfi_check() validation. This isn’t compatible with stand-alone
assembly code, which the compiler doesn’t instrument, and would
result in indirect calls to assembly code to fail. Therefore, we
default to using non-canonical jump tables instead, where the compiler
generates a local jump table entry <function>.cfi_jt for each
address-taken function, and replaces all references to the function
with the address of the jump table entry.
Note that because non-canonical jump table addresses are local
to each component, they break cross-module function address
equality. Specifically, the address of a global function will be
different in each module, as it's replaced with the address of a local
jump table entry. If this address is passed to a different module,
it won’t match the address of the same function taken there. This
may break code that relies on comparing addresses passed from other
components.
CFI checking can be disabled in a function with the __nocfi attribute.
Additionally, CFI can be disabled for an entire compilation unit by
filtering out CC_FLAGS_CFI.
By default, CFI failures result in a kernel panic to stop a potential
exploit. CONFIG_CFI_PERMISSIVE enables a permissive mode, where the
kernel prints out a rate-limited warning instead, and allows execution
to continue. This option is helpful for locating type mismatches, but
should only be enabled during development.

Since we're about to move drm_dp_helper.c over to drm_dbg_*(), we'll want
to make sure that we can also add ratelimited versions of these macros in
order to retain some of the previous debugging output behavior we had.
However, as I was preparing to do this I noticed that the current
rate limited macros we have are kind of bogus. It looks like when I wrote
these, I didn't notice that we'd always be calling __ratelimit() even if
the debugging message we'd be printing would normally be filtered out due
to the relevant DRM debugging category being disabled.
So, let's fix this by making sure to check drm_debug_enabled() in our
ratelimited macros before calling __ratelimit(), and start using
drm_dev_printk() in order to print debugging messages since that will save
us from doing a redundant drm_debug_enabled() check. And while we're at it,
let's move the code for this into another macro that we can reuse for
defining new ratelimited DRM debug macros more easily.

With recent changes that separated action module load from action
initialization tcf_action_init() function error handling code was modified
to manually release the loaded modules if loading/initialization of any
further action in same batch failed. For the case when all modules
successfully loaded and some of the actions were initialized before one of
them failed in init handler. In this case for all previous actions the
module will be released twice by the error handler: First time by the loop
that manually calls module_put() for all ops, and second time by the action
destroy code that puts the module after destroying the action.
Reproduction:
$ sudo tc actions add action simple sdata \"2\" index 2
$ sudo tc actions add action simple sdata \"1\" index 1 \
action simple sdata \"2\" index 2
RTNETLINK answers: File exists
We have an error talking to the kernel

$ sudo tc actions flush action simple

$ sudo tc actions add action simple sdata \"2\" index 2
Error: Failed to load TC action module.
We have an error talking to the kernel
$ lsmod | grep simple
act_simple 20480 -1
Fix the issue by modifying module reference counting handling in action
initialization code:
- Get module reference in tcf_idr_create() and put it in tcf_idr_release()
instead of taking over the reference held by the caller.
- Modify users of tcf_action_init_1() to always release the module
reference which they obtain before calling init function instead of
assuming that created action takes over the reference.
- Finally, modify tcf_action_init_1() to not release the module reference
when overwriting existing action as this is no longer necessary since both
upper and lower layers obtain and manage their own module references
independently.

Action init code increments reference counter when it changes an action.
This is the desired behavior for cls API which needs to obtain action
reference for every classifier that points to action. However, act API just
needs to change the action and releases the reference before returning.
This sequence breaks when the requested action doesn't exist, which causes
act API init code to create new action with specified index, but action is
still released before returning and is deleted (unless it was referenced
concurrently by cls API).
Reproduction:
$ sudo tc actions ls action gact
$ sudo tc actions change action gact drop index 1
$ sudo tc actions ls action gact
Extend tcf_action_init() to accept 'init_res' array and initialize it with
action->ops->init() result. In tcf_action_add() remove pointers to created
actions from actions array before passing it to tcf_action_put_many().

Some Chromebooks use hard-coded interrupts in their ACPI tables.
This is an excerpt as dumped on Relm:
...
Name (_HID, "ELAN0001") // _HID: Hardware ID
Name (_DDN, "Elan Touchscreen ") // _DDN: DOS Device Name
Name (_UID, 0x05) // _UID: Unique ID

{
0x000000B8,
}
})
Return (BUF0) /* \_SB_.I2C1.ETSA._CRS.BUF0 */
}
...
This interrupt is hard-coded to 0xB8 = 184 which is too high to be mapped
to IO-APIC, so no triggering information is propagated as acpi_register_gsi()
fails and irqresource_disabled() is issued, which leads to erasing triggering
and polarity information.
Do not overwrite flags as it leads to erasing triggering and polarity
information which might be useful in case of hard-coded interrupts.
This way the information can be read later on even though mapping to
APIC domain failed.

struct rapl_package is declared twice in intel_rapl.h, once at line 80

Code inspection suggests that the first instance should be struct
rapl_domain rather than rapl_package, so change it.

Move the busy check and disk-wide sync into the only caller, so that
the remainder can be shared with del_gendisk. Also pass the gendisk

1. Few cleanups.
2. Add debug statistics to Tegra20 memory controller.
3. Update bindings and convert to dtschema. This update is not
backwards compatible (ABI break) however the broken part was added
recently (v5.11) and there are no users of it yet.

ARM SCMI updates for v5.13
The major and big addition this time is to support modularisation of
individual SCMI protocols thus enabling to add support for vendors'
custom SCMI protocol. This changes the interface provided by the SCMI
driver to all the users of SCMI and hence involved changes in various
other subsystem SCMI drivers. The change has been split with a bit of
transient code to preserve bisectability and avoiding one big patch bomb
changing all the users.
This also includes SCMI IIO driver(pulled from IIO tree) and support for
per-cpu DVFS.

There is a timer wrap issue on dra7 for the ARM architected timer.
In a typical clock configuration the timer fails to wrap after 388 days.
To work around the issue, we need to use timer-ti-dm percpu timers instead.
Let's configure dmtimer3 and 4 as percpu timers by default, and warn about
the issue if the dtb is not configured properly.
Let's do this as a single patch so it can be backported to v5.8 and later
kernels easily. Note that this patch depends on earlier timer-ti-dm
systimer posted mode fixes, and a preparatory clockevent patch
"clocksource/drivers/timer-ti-dm: Prepare to handle dra7 timer wrap issue".
For more information, please see the errata for "AM572x Sitara Processors
Silicon Revisions 1.1, 2.0":
https://www.ti.com/lit/er/sprz429m/sprz429m.pdf
The concept is based on earlier reference patches done by Tero Kristo and
Keerthy.

Tag for the input subsystem to pick up

Current simple-card / audio-graph creates 1xCPU + 1xCodec + 1xPlatform
for all dai_link, but some of them is not needed.
For example Platform is not needed for DPCM BE case.
Moreover, we can share snd-soc-dummy DAI for CPU-dummy / dummy-Codec
in DPCM.
This patch adds dummy DAI and share it when DPCM case,
I beliave it can contribute to reduce memory.
By this patch, CPU-dummy / dummy-CPU are set at asoc_simple_init_priv(),
thus, its settings are no longer needed at DPCM detecting timing
on simple-card / audio-graph.
Moreover, we can remove triky Platform settings code for DPCM BE,
because un-needed Platform is not created.

We can't rely on the contents of the devres list during
spi_unregister_controller(), as the list is already torn down at the
time we perform devres_find() for devm_spi_release_controller. This
causes devices registered with devm_spi_alloc_{master,slave}() to be
mistakenly identified as legacy, non-devm managed devices and have their
reference counters decremented below 0.

Some HW/driver can support passing ethernet rx decap frames and
raw 802.11 frames for the monitor interface concurrently and
via separate RX calls to mac80211. Packets going to the monitor
interface(s) would be in 802.11 format and thus not have the
RX_FLAG_8023 set, and 802.11 format monitoring frames should have
RX_FLAG_ONLY_MONITOR set.
Drivers doing such can enable the SUPPORTS_CONC_MON_RX_DECAP to
allow using ethernet decap offload while a monitor interface is
active, currently RX decapsulation offload gets disabled when a
monitor interface is added.
