WS X570-ACE has a T_Sensor header on board according to manual[1].
I'm using a 10kΩ B=3435K thermsistor attached to the header of WS X570-ACE.
EC byte at 0x3d matches readings from BIOS sensor page and environment temperature.

With the removal of seq_get_buf in blkcg_print_one_stat, we
cannot make adding the newline conditional on there being
relevant stats because the name was already written out
unconditionally.
Otherwise we may end up with multiple device names in one
line which is confusing and doesn't follow the nested-keyed
file format.

Calling synchronize_irq() right before free_irq() is quite useless. On one
hand the IRQ can easily fire again before free_irq() is entered, on the
other hand free_irq() itself calls synchronize_irq() internally (in a race
condition free way), before any state associated with the IRQ is freed.

As per Errata Section 5.1, if EEE is intended to be used, some register
writes must be done once after every hardware reset. This patch now adds
the necessary register writes as listed in the Marvell errata.
Without this fix we experience ethernet problems on some of our boards
equipped with a new version of this ethernet PHY (different supplier).
The fix applies to Marvell Alaska 88E1510/88E1518/88E1512/88E1514

If user space provides smaller buffer than the IPC4 reply then it is
possible that we corrupt user space memory since the IPC4 dfs_read function
is not using the count directly in copy_to_user() due to the nature of
an IPC4 message.
Cap the remaining counter to make sure that we are not writing too much to
the user space provided buffer.
Add a check also to make sure that the buffer is at least the size of the
IPC4 header.

firmware generation and thus the '+' suffix. Introduciton of IMR,
removal of CLDMA, D0IX support and monolithic-ation of library/module

AVS driver operates with granular audio card division in mind.
Super-card approach (e.g.: I2S, DMIC and HDA DAIs combined) is
deprecated in favour of individual cards - one per each device. This
provides necessary dynamism, especially for configurations with number
of codecs present and makes it easier to survive auxiliary devices
failures - one card failing to probe does not prevent others from
succeeding.
All boards spawned by AVS are unregistered on ->remove(). This includes
dummy codecs such as DMIC.
As all machine boards found in sound/soc/intel/boards are irreversibly
tied to 'super-card' approach, new boards are going to be introduced.
This temporarily increases number of boards available under /intel
directory until skylake-driver becomes deprecated and removed.

Audio DSP device supports D0 substates in form of D0ix, allowing for
preserving more power even when device is still considered active (D0).
When entered, certain domains which are not being currently used become
power gated. Entering and leaving D0ix is a complex process and differs
between firmware generations.
Conditions that disallow D0i3 and require immediate D0i0 transition
include but may not be limited to: IPC traffic, firmware tracing and
SRAM I/O. To make D0ix toggling sane, delay D0i3 transition and refresh
the timer each time an IPC is requested.

HDA streaming in DSP world means enlisting HDAudio links as BE
interfaces. Another difference when compared to its DMIC and I2S friends
is lack of NHLT blob usage - no additional hardware configuration is
needed.
Similarly to I2S component, HDA populates its DAIs dynamically, here by
the means of codec->pcm_list_head. Allows for cutting the number of soc
components required to support the interface.

Not all modules are part of base firmware. Some are part of loadable
libraries. These need to be loaded after base firmware reports ready
status through FW_READY notification.
Their loading process is similar to the base firmware's one. Request the
binary file, verify and strip the manifest and load the actual code into
DSP memory with help of CLDMA or HD-Audio render stream, depending on
audio device generation.
List of libraries needed for loading is obtained through the topology -
vendor sections specifying the name of firmware files to request.

In vmxnet3_rq_create(), when dma_alloc_coherent() fails,
vmxnet3_rq_destroy() is called. It sets rq->rx_ring[i].base to NULL. Then
vmxnet3_rq_create() returns an error to its callers mxnet3_rq_create_all()
-> vmxnet3_change_mtu(). Then vmxnet3_change_mtu() calls
vmxnet3_force_close() -> dev_close() in error handling code. And the driver
calls vmxnet3_close() -> vmxnet3_quiesce_dev() -> vmxnet3_rq_cleanup_all()
-> vmxnet3_rq_cleanup(). In vmxnet3_rq_cleanup(),
rq->rx_ring[ring_idx].base is accessed, but this variable is NULL, causing
a NULL pointer dereference.
To fix this possible bug, an if statement is added to check whether
rq->rx_ring[0].base is NULL in vmxnet3_rq_cleanup() and exit early if so.
The error log in our fault-injection testing is shown as follows:

In vmxnet3_rq_alloc_rx_buf(), when dma_map_single() fails, rbi->skb is

rbi->page is also freed. In the two cases, vmxnet3_rq_alloc_rx_buf()
returns an error to its callers vmxnet3_rq_init() -> vmxnet3_rq_init_all()

vmxnet3_rq_cleanup_all() in error handling code, and rbi->skb or rbi->page

* irq/gic-v3-nmi-fixes-5.19:
: .
: GICv3 pseudo-NMI fixes from Mark Rutland:
:
: "These patches fix a couple of issues with the way GICv3 pseudo-NMIs are
: handled:
:
: * The first patch adds a barrier we missed from NMI handling due to an
: oversight.
:
: * The second patch refactors some logic around reads from ICC_IAR1_EL1
: and adds commentary to explain what's going on.
:
: * The third patch descends into madness, reworking gic_handle_irq() to
: consistently manage ICC_PMR_EL1 + DAIF and avoid cases where these can
: be left in an inconsistent state while softirqs are processed."

The passive governor requires the cpu data to get the next target frequency
of devfreq device if depending on cpu. In order to reduce the unnecessary
memory data, keep cpufreq_policy data for possible cpus instead of NR_CPU.

In order to keep the consistent coding style between passive_devfreq
and passive_cpufreq, use common code for handling required opp property.
Also remove the unneed conditional statement and unify the comment
of both passive_devfreq and passive_cpufreq when getting the target frequency.

Many CPU architectures have caches that can scale independent of the
CPUs. Frequency scaling of the caches is necessary to make sure that the
cache is not a performance bottleneck that leads to poor performance and
power. The same idea applies for RAM/DDR.
To achieve this, this patch adds support for cpu based scaling to the
passive governor. This is accomplished by taking the current frequency
of each CPU frequency domain and then adjust the frequency of the cache
(or any devfreq device) based on the frequency of the CPUs. It listens
to CPU frequency transition notifiers to keep itself up to date on the
current CPU frequency.
To decide the frequency of the device, the governor does one of the
following:
* Derives the optimal devfreq device opp from required-opps property of
the parent cpu opp_table.
* Scales the device frequency in proportion to the CPU frequency. So, if
the CPUs are running at their max frequency, the device runs at its
max frequency. If the CPUs are running at their min frequency, the
device runs at its min frequency. It is interpolated for frequencies
in between.

swiotlb_find_slots() skips slots according to io tlb aligned mask
calculated from min aligned mask and original physical address
offset. This affects max mapping size. The mapping size can't
achieve the IO_TLB_SEGSIZE * IO_TLB_SIZE when original offset is
non-zero. This will cause system boot up failure in Hyper-V
Isolation VM where swiotlb force is enabled. Scsi layer use return
value of dma_max_mapping_size() to set max segment size and it
finally calls swiotlb_max_mapping_size(). Hyper-V storage driver
sets min align mask to 4k - 1. Scsi layer may pass 256k length of
request buffer with 0~4k offset and Hyper-V storage driver can't
get swiotlb bounce buffer via DMA API. Swiotlb_find_slots() can't
find 256k length bounce buffer with offset. Make swiotlb_max_mapping
_size() take min align mask into account.

Not all of these drivers are needed on every ARCH_SUNXI platform. In
particular, the ARCH_SUNXI symbol will be reused for the Allwinner D1,
a RISC-V SoC which contains none of these irqchips.
Introduce Kconfig symbols so we can select only the drivers actually
used by a particular set of platforms. This also lets us move the
irqchip driver dependencies to a more appropriate location.

The global blackhole_netdev has replaced pernet loopback_dev to become the
one given to the object that holds an netdev when ifdown in many places of
ipv4 and ipv6 since commit 8d7017fd621d ("blackhole_netdev: use
blackhole_netdev to invalidate dst entries").
Especially after commit faab39f63c1f ("net: allow out-of-order netdev
unregistration"), it's no longer safe to use loopback_dev that may be
freed before other netdev.
This patch is to set dst dev to blackhole_netdev instead of loopback_dev
in ifdown.
v1->v2:
- add Fixes tag as Eric suggested.
