Pull CXL (Compute Express Link) updates from Dan Williams:
"This subsystem is still in the build-out phase as the bulk of the
update is improvements to enumeration and fleshing out the device
model. In terms of new features, more mailbox commands have been added
to the allowed-list in support of persistent memory provisioning
support targeting v5.15.
The critical update from an enumeration perspective is support for the
CXL Fixed Memory Window Structure that indicates to Linux which system
physical address ranges decode to the CXL Host Bridges in the system.
This allows the driver to detect which address ranges have been mapped
by firmware and what address ranges are available for future hotplug.
So, again, mostly skeleton this round, with more meat targeting v5.15.
Summary:
- Add support for the CXL Fixed Memory Window Structure, a recent
extension of the ACPI CEDT (CXL Early Discovery Table)
- Add infrastructure for component registers
- Add HDM (Host-managed device memory) decoder definitions
- Define a device model for an HDM decoder tree
- Bridge CXL persistent memory capabilities to an NVDIMM bus /
device-model
- Switch to fine grained mapping of CXL MMIO registers to allow
different drivers / system software to own individual register
blocks
- Enable media provisioning commands, and publish the label storage
area size in sysfs
- Miscellaneous cleanups and fixes"

Commit d2bcbeab4200 ("scsi: blkcg: Add app identifier support for
blkcg") introduced an FC_APPID config option under SCSI. However, the
added config option is not used anywhere. Simply remove it.
The block layer BLK_CGROUP_FC_APPID config option is what actually
controls whether the application ID code should be built or not. Make
this option dependent on NVMe over FC since that is currently the only
transport which supports the capability.

Add a new PCI driver which register a thermal zone and allows to get
notification for threshold violation by a RW trip point. These
notifications are delivered from the device using MSI based
interrupt.
The main difference between this new PCI driver and the existing
one is that the temperature and trip points directly use PCI
MMIO instead of using ACPI methods.
This driver registers a thermal zone "TCPU_PCI" in addition to the
legacy processor thermal device, which uses ACPI companion device
to set name, temperature and trips.
This driver is enabled for AlderLake.

Remove enumeration part from the processor_thermal_device to two
different modules. One for ACPI and one for PCI:
ACPI enumeration: int3401_thermal
PCI part: processor_thermal_device_pci_legacy
The current processor_thermal_device now just implements interface
functions to be used by the ACPI and PCI enumeration module. This is
done by:
1. Make functions proc_thermal_add() and proc_thermal_remove() non static
and export them for usage in other processor_thermal_device_pci_legacy.c
and in int3401_thermal.c.
2. Move the sysfs file creation for TCC offset and power limit attribute
group to the proc_thermal_add() from the individual enumeration callbacks
for PCI and ACPI.
3. Create new interface functions proc_thermal_mmio_add() and
proc_thermal_mmio_remove() which will be called from the
processor_thermal_device_pci_legacy module.
4. Export proc_thermal_resume(), so that it can be used by power
management callbacks.
5. Remove special check for double enumeration as it never happens.
While here, fix some cleanup on error conditions in proc_thermal_add().
No functional changes are expected with this change.

- Added option for per CPU threads to the hwlat tracer
- Have hwlat tracer handle hotplug CPUs
- New tracer: osnoise, that detects latency caused by interrupts,
softirqs and scheduling of other tasks.
- Added timerlat tracer that creates a thread and measures in detail
what sources of latency it has for wake ups.
- Removed the "success" field of the sched_wakeup trace event. This has
been hardcoded as "1" since 2015, no tooling should be looking at it
now. If one exists, we can revert this commit, fix that tool and try
to remove it again in the future.
- tgid mapping fixed to handle more than PID_MAX_DEFAULT pids/tgids.
- New boot command line option "tp_printk_stop", as tp_printk causes
trace events to write to console. When user space starts, this can
easily live lock the system. Having a boot option to stop just after
boot up is useful to prevent that from happening.
- Have ftrace_dump_on_oops boot command line option take numbers that
match the numbers shown in /proc/sys/kernel/ftrace_dump_on_oops.

virtio_disable_cb is currently a nop for split ring with event index.
This is because it used to be always called from a callback when we know
device won't trigger more events until we update the index. However,
now that we run with interrupts enabled a lot we also poll without a
callback so that is different: disabling callbacks will help reduce the
number of spurious interrupts.
Further, if using event index with a packed ring, and if being called
from a callback, we actually do disable interrupts which is unnecessary.
Fix both issues by tracking whenever we get a callback. If that is
the case disabling interrupts with event index can be a nop.
If not the case disable interrupts. Note: with a split ring
there's no explicit "no interrupts" value. For now we write
a fixed value so our chance of triggering an interupt
is 1/ring size. It's probably better to write something
related to the last used index there to reduce the chance
even further. For now I'm keeping it simple.

It's unsafe to operate a vq from multiple threads.
Unfortunately this is exactly what we do when invoking

Same happens with napi-tx even without the
opportunistic cleaning from the receive interrupt: that races
with processing the vq in start_xmit.
As a fix move everything that deals with the vq to under tx lock.

In order to support running vdpa using vritio_vdpa driver, we need to
create a different kind of MR, one that has 1:1 mapping, since the
addresses referring to virtqueues are dma addresses.
We create the 1:1 MR in mlx5_vdpa_dev_add() only in case firmware
supports the general capability umem_uid_0. The reason for that is that
1:1 MRs must be created with uid == 0 while virtqueue objects can be
created with uid == 0 only when the firmware capability is on.
If the set_map() callback is called with new translations provided
through iotlb, the driver will destroy the 1:1 MR and create a regular
one.

Before SF support was introduced, the DMA device was equal to
mdev->device which was in essence equal to pdev->dev.
With SF introduction this is no longer true. It has already been
handled for vhost_vdpa since the reference to the dma device can from
within mlx5_vdpa. With virtio_vdpa this broke. To fix this we set the
real dma device when initializing the device.
In addition, for the sake of consistency, previous references in the
code to the dma device are changed to vdev->dma_dev.

But now sector_t and blkcnt_t are always 64-bit in size.

and/or nice improvements.
Here are some highlights:
Core:
- A new framing access mode for rawmidi to get timestamps
- Cleanup / refactoring of buffer memory management helper code
- Support for automatic negotiation of ASoC DAI formats
- Revival of software suspend for PCM and control core, as a
preliminary work for PCI BAR rescan support

Commit dacce2be3312 ("vmxnet3: add geneve and vxlan tunnel offload
support") added support for encapsulation offload. However, the inner
offload capability is to be restricted to UDP tunnels with default
Vxlan and Geneve ports.
This patch fixes the issue for tunnels with non-default ports using
features check capability and filtering appropriate features for such
tunnels.

The current location of the callback delete can lead to a race
condition where deleting the callback requires a write_lock on
the nf_table, but at the same time another thread from netfilter
could have taken a read lock on the table before trying to offload.
Since the driver is taking a rtnl_lock this can lead into a deadlock
situation, where the netfilter offload will wait for the cls_flower
rtnl_lock to be released, but this cannot happen since this is
waiting for the nf_table read_lock to be released before it can
delete the callback.
Solve this by completely removing the nf_flow_table_offload_del_cb
call, as this will now be cleaned up by act_ct itself when cleaning
up the specific nf_table.

Pull asm/unaligned.h unification from Arnd Bergmann:
"Unify asm/unaligned.h around struct helper
The get_unaligned()/put_unaligned() helpers are traditionally
architecture specific, with the two main variants being the
"access-ok.h" version that assumes unaligned pointer accesses always
work on a particular architecture, and the "le-struct.h" version that
casts the data to a byte aligned type before dereferencing, for
architectures that cannot always do unaligned accesses in hardware.
Based on the discussion linked below, it appears that the access-ok
version is not realiable on any architecture, but the struct version
probably has no downsides. This series changes the code to use the
same implementation on all architectures, addressing the few
exceptions separately"
