those bindings are not used anymore.
A comment in drivers/edac/mpc85xx_edac.c say they are to be removed
with kernel 2.6.30.

When SRBDS is mitigated by TSX OFF, update_srbds_msr() will still read
and write to MSR_IA32_MCU_OPT_CTRL even when that MSR is not supported
due to not having loaded the appropriate microcode.
Check for X86_FEATURE_SRBDS_CTRL which is set only when the respective
microcode which adds MSR_IA32_MCU_OPT_CTRL is loaded.
Based on a patch by Thadeu Lima de Souza Cascardo <cascardo@canonical.com>.

The kunit_remove_resource() function is used to unlink a resource from
the list of resources in the test, making it no longer show up in
kunit_find_resource().
However, this could lead to a race condition if two threads called
kunit_remove_resource() on the same resource at the same time: the
resource would be removed from the list twice (causing a crash at the
second list_del()), and the refcount for the resource would be
decremented twice (instead of once, for the reference held by the
resource list).
Fix both problems, the first by using list_del_init(), and the second by
checking if the resource has already been removed using list_empty(),
and only decrementing its refcount if it has not.
Also add a KUnit test for the kunit_remove_resource() function which
tests this behaviour.

Add KUnit tests to the hlist linked-list structure which is used by
hashtables. This should give coverage of every function and macro in
list.h, as well as (combined with the KUnit tests for the hash
functions) get very close to having tests for the hashtable structure.
The tests here mirror the existing list tests, and are found in a new

In mce_threshold_create_device(), if threshold_create_bank() fails, the
previously allocated threshold banks array @bp will be leaked because
the call to mce_threshold_remove_device() will not free it.
This happens because mce_threshold_remove_device() fetches the pointer
through the threshold_banks per-CPU variable but bp is written there
only after the bank creation is successful, and not before, when
threshold_create_bank() fails.
Add a helper which unwinds all the bank creation work previously done
and pass into it the previously allocated threshold banks array for
freeing.

The asm constraint does not reflect the fact that the asm statement can
modify the value of the local variable loops. Which it does.
Specifying the wrong constraint may lead to undefined behavior, it may
clobber random stuff (e.g. local variable, important temporary value in
regs, etc.). This is especially dangerous when the compiler decides to
inline the function and since it doesn't know that the value gets
modified, it might decide to use it from a register directly without
reloading it.
Change the constraint to "+a" to denote that the first argument is an
input and an output argument.

Allow the component debugfs_prefix to be set from
snd_soc_component_driver. First use case is avoiding a duplicate
debugfs entry error in case a device has multiple components
which have the same name therefore.
Note that we don't set component->debugfs_prefix if it's set already.
That's needed because partially component->debugfs_prefix is set
before calling snd_soc_component_initialize().

AK4613 has STEREO/TDM512/TDM256/TDM128 mode.
Renesas is the only user of ak4613 on upstream for now,
and is using it as STEREO mode, because of board connection.
Thus, current driver is supporting STEREO mode only, and other
modes are not supported.
But I noticed that I can try first 2ch out of TDM256 mode 8ch
Playback even in such a situation.
But because of board connection, I can't test full TDM256 mode,
and/or other TDM mode. Thus I don't want to add new DT propaty for now.
This patch enables TDM256 mode test by "ifdef style",
but it has no effect to current supported STEREO mode.
You can define AK4613_ENABLE_TDM_TEST to try TDM256 mode.
Please don't hesitate to break current code if you can add full TDM256
and/or other TDM mode. You don't need to care compatibility with Renesas.

Create a new kunit test for soc-utils and use it to test
snd_soc_tdm_params_to_bclk().
The test uses a table of values to avoid the possibility that an
on-the-fly generator contains the same algorithmic error as the
function-under-test and so fails to detect a bug.
There is no need to test every possible combination of values.

Add a helper function snd_soc_tdm_params_to_bclk() to calculate
the bclk from params info and the tdm sots configuration.
When using a TDM frame of N slots of width W bits:
bclk = sample_rate * N * W
As a convenience to simplify calling code, if the slot count or
slot width are 0 a value will be obtained from the params. This
allows calling code to use this one function to handle cases of
TDM where only one parameter is fixed, or I2S where the slot width
is fixed (for example to set a 32-bit slot for 24-bit samples).
Also as a convenience the slot count can optionally be rounded up
to a multiple. This is mainly useful for I2S systems, since I2S has
two phases of LRCLK the number of slots is always a multiple of 2.

amd_cache_northbridges() is exported by amd_nb.c and is called by
amd64-agp.c and amd64_edac.c modules at module_init() time so that NB
descriptors are properly cached before those drivers can use them.
However, the init_amd_nbs() initcall already does call
amd_cache_northbridges() unconditionally and thus makes sure the NB
descriptors are enumerated.
That initcall is a fs_initcall type which is on the 5th group (starting
from 0) of initcalls that gets run in increasing numerical order by the
init code.
The module_init() call is turned into an __initcall() in the MODULE=n
case and those are device-level initcalls, i.e., group 6.
Therefore, the northbridges caching is already finished by the time
module initialization starts and thus the correct initialization order
is retained.
Unexport amd_cache_northbridges(), update dependent modules to
call amd_nb_num() instead. While at it, simplify the checks in
amd_cache_northbridges().

After resuming from suspend-to-RAM, the MSRs that control CPU's
speculative execution behavior are not being restored on the boot CPU.
These MSRs are used to mitigate speculative execution vulnerabilities.
Not restoring them correctly may leave the CPU vulnerable. Secondary
CPU's MSRs are correctly being restored at S3 resume by
identify_secondary_cpu().
During S3 resume, restore these MSRs for boot CPU when restoring its

The mechanism to save/restore MSRs during S3 suspend/resume checks for
the MSR validity during suspend, and only restores the MSR if its a
valid MSR. This is not optimal, as an invalid MSR will unnecessarily
throw an exception for every suspend cycle. The more invalid MSRs,
higher the impact will be.
Check and save the MSR validity at setup. This ensures that only valid
MSRs that are guaranteed to not throw an exception will be attempted
during suspend.

In 1394 OHCI specification, descriptor of Asynchronous Receive DMA context
has timeStamp field in its trailer quadlet. The field is written by
the host controller for the time to receive asynchronous request
subaction in isochronous cycle time.
In Linux FireWire subsystem, the value of field is stored to fw_packet
structure and copied to fw_request structure as the part. The fw_request
structure is hidden from unit driver and passed as opaque pointer when
calling registered handler. It's inconvenient to the unit driver which
needs timestamp of packet.
This commit adds kernel API to pick up timestamp from opaque pointer to
fw_request structure.

1394 OHCI specification defined Isochronous Cycle Timer Register to get
value of CYCLE_TIME register defined by IEEE 1394 for CSR architecture
defined by ISO/IEC 13213. Unit driver can calculate packet time by
compute with the value of CYCLE_TIME and timeStamp field in descriptor
of each isochronous and asynchronous context. The resolution of CYCLE_TIME
is 49.576 MHz, while the one of timeStamp is 8,000 Hz.
Current implementation of Linux FireWire subsystem allows the driver to
get the value of CYCLE_TIMER CSR register by transaction service. The
transaction service has overhead in regard of access to MMIO register.
This commit adds kernel API for unit driver to access the register

This fixes segfaults when a card gets yanked off of the PCIe bus while
busy, e.g. with a userspace app trying to get the cycle time:

As long as reading commit 20802224298c ("firewire: core: add forgotten
dummy driver methods, remove unused ones"), three functions are not
implemeted in dummy driver for reason; .read_csr, .write_csr, and
.set_config_rom.
In core of Linux FireWire subsystem, the callback of .set_config_rom is
under acquisition of mutual exclusive for local list of card. The
acquision is also done in process for removal of card, therefore it's
safe for missing implementation of .set_config_rom.
On the other hand, no lock primitive accompanies any call of .read_csr and
.write_csr. For userspace client, check of node shutdown is done in the
beginning of dispatch of ioctl request, while node shifts to shutdown
state in workqueue context enough after card shifts to dummy driver. It's
probable that these two functions are called for the dummy driver by the
code of userspace client. In-kernel unit driver has similar situation.
It's better to add implementation of the two functions for dummy driver.

In systems with only a discrete i915 GPU, the acomp init will
always timeout for the PCH HDA controller instance.
Avoid the timeout by checking the PCI device hierarchy
whether any display class PCI device can be found on the system,
and at the same level as the HDA PCI device. If found, proceed
with the acomp init, which will wait until i915 probe is complete
and component binding can proceed. If no matching display
device is found, the audio component bind can be safely skipped.
The bind timeout will still be hit if the display is present
in the system, but i915 driver does not bind to it by configuration
choice or probe error. In this case the 60sec timeout will be
hit.

iommu_get_domain_for_dev() is already perfectly happy to return NULL
if the given device has no IOMMU. Drop the unnecessary check in favour
of just handling that condition appropriately.

arch/powerpc/include/asm/prom.h includes some headers that it doesn't need
itself. Add the missing headers to files that include prom.h so we can
remove them from prom.h.

Currently when XDP rings are created, each descriptor gets its DD bit
set, which turns out to be the wrong approach as it can lead to a
situation where more descriptors get cleaned than it was supposed to,
e.g. when AF_XDP busy poll is run with a large batch size. In this
situation, the driver would request for more buffers than it is able to
handle.
Fix this by not setting the DD bits in ice_xdp_alloc_setup_rings(). They
should be initialized to zero instead.
