If the no_hash_pointers command line parameter is set, then
printk("%p") will print pointers as unhashed, which is useful for
debugging purposes. This change applies to any function that uses
vsprintf, such as print_hex_dump() and seq_buf_printf().
A large warning message is displayed if this option is enabled.
Unhashed pointers expose kernel addresses, which can be a security
risk.
Also update test_printf to skip the hashed pointer tests if the
command-line option is set.

AM65 NUSS ethernet switch on K3 devices can be configured to work either
in independent mac mode where each port acts as independent network
interface (multi mac) or switch mode.
Add devlink hooks to provide a way to switch b/w these modes.
Rationale to use devlink instead of defaulting to bridge mode is that
SoC use cases require to support multiple independent MAC ports with no
switching so that users can use software bridges with multi-mac
configuration (e.g: to support LAG, HSR/PRP, etc). Also, switching
between multi mac and switch mode requires significant Port and ALE
reconfiguration, therefore is easier to be made as part of mode change
devlink hooks. It also allows to keep user interface similar to what
was implemented for the previous generation of TI CPSW IP
(on AM33/AM43/AM57 SoCs).

For the security reason, normal printk will show the hashed
pointer value (encrypted by random number) with %p to printk
buffer to hide the real address. But the tracefs/trace always
shows real address for debug. To bridge those outputs, add an
option to switch the output format. Ftrace users can use it
to find the hashed value corresponding to the real address
in trace log.

Add support for offloading of HSR/PRP (IEC 62439-3) tag insertion
tag removal, duplicate generation and forwarding.
For HSR, insertion involves the switch adding a 6 byte HSR header after
the 14 byte Ethernet header. For PRP it adds a 6 byte trailer.
Tag removal involves automatically stripping the HSR/PRP header/trailer
in the switch. This is possible when the switch also performs auto
deduplication using the HSR/PRP header/trailer (making it no longer
required).
Forwarding involves automatically forwarding between redundant ports in
an HSR. This is crucial because delay is accumulated as a frame passes
through each node in the ring.
Duplication involves the switch automatically sending a single frame
from the CPU port to both redundant ports. This is required because the
inserted HSR/PRP header/trailer must contain the same sequence number
on the frames sent out both redundant ports.
Export is_hsr_master so DSA can tell them apart from other devices in
dsa_slave_changeupper.

It is recommended to not specifiy clocks property in an endpoint subnode.
This series moves clocks to device node.
However after moving the clocks to device node, the audio playback or
capture fails. The specified clock is not actually getting enabled and
hence the failure is seen. There seems to be a bug in simple-card-utils.c
where clock handle is not assigned when parsing clocks from device node.
Fix the same and revert original change which actually added clocks
property in endpoint subnode. Also update Jetson AGX Xavier DT where the
usage is found.

When a Linux VM runs on Hyper-V, if the host toolstack doesn't support
hibernation for the VM (this happens on old Hyper-V hosts like Windows
Server 2016, or new Hyper-V hosts if the admin or user doesn't declare
the hibernation intent for the VM), the VM is discouraged from trying
hibernation (because the host doesn't guarantee that the VM's virtual
hardware configuration will remain exactly the same across hibernation),
i.e. the VM should not try to set up the swap partition/file for
hibernation, etc.
x86 Hyper-V uses the presence of the virtual ACPI S4 state as the
indication of the host toolstack support for a VM. Currently there is
no easy and reliable way for the userspace to detect the presence of
the state (see https://lkml.org/lkml/2020/12/11/1097). Add
/sys/bus/vmbus/hibernation for this purpose.

Per ZBC and ZAC specifications, host-managed SMR hard-disks mandate that
all writes into sequential write required zones be aligned to the device
physical block size. However, NVMe ZNS does not have this constraint and
allows write operations into sequential zones to be aligned to the
device logical block size. This inconsistency does not help with
software portability across device types.
To solve this, introduce the zone_write_granularity queue limit to
indicate the alignment constraint, in bytes, of write operations into
zones of a zoned block device. This new limit is exported as a
read-only sysfs queue attribute and the helper
blk_queue_zone_write_granularity() introduced for drivers to set this
limit.
The function blk_queue_set_zoned() is modified to set this new limit to
the device logical block size by default. NVMe ZNS devices as well as
zoned nullb devices use this default value as is. The scsi disk driver
is modified to execute the blk_queue_zone_write_granularity() helper to
set the zone write granularity of host-managed SMR disks to the disk
physical block size.
The accessor functions queue_zone_write_granularity() and
bdev_zone_write_granularity() are also introduced.

Currently, whether the alloc/free stack traces collection is enabled by
default for hardware tag-based KASAN depends on CONFIG_DEBUG_KERNEL.
The intention for this dependency was to only enable collection on slow
debug kernels due to a significant perf and memory impact.
As it turns out, CONFIG_DEBUG_KERNEL is not considered a debug option
and is enabled on many productions kernels including Android and Ubuntu.
As the result, this dependency is pointless and only complicates the
code and documentation.
Having stack traces collection disabled by default would make the
hardware mode work differently to to the software ones, which is
confusing.
This change removes the dependency and enables stack traces collection
by default.
Looking into the future, this default might makes sense for production
kernels, assuming we implement a fast stack trace collection approach.

User sets it to 1 or 0 to enable or disable threaded mode.
Note: when switching between threaded and the current softirq based mode

of some oddballs.
I dropped the 'm25p.*-nonjedec' compatible strings as these don't appear

It turns out allowing non-contigous allocations here was a rather bad
idea, as we'll now need to define ways to get the pages for mmaping
or dma_buf sharing. Revert this change and stick to the original
concept. A different API for the use case of non-contigous allocations
will be added back later.

"make dtbs_check" complains that the number of interconnect-cells
for some RPMh platforms is not "const: 1" (as defined in the schema).
That's because the interconnect-cells now can be 1 or 2, depending
on what is supported by the specific interconnect provider. Let's
reflect this in the schema.

Intel Moorestown and Medfield are quite old Intel Atom based
32-bit platforms, which were in limited use in some Android phones,
tablets and consumer electronics more than eight years ago.
There are no bugs or problems ever reported outside from Intel
for breaking any of that platforms for years. It seems no real
users exists who run more or less fresh kernel on it. Commit
05f4434bc1 ("ASoC: Intel: remove mfld_machine") is also in align
with this theory.
Due to above and to reduce a burden of supporting outdated drivers,
remove the support for outdated platforms completely.

Admitedly, passing id_aa64mmfr1.vh=0 on the command-line isn't
that easy to understand, and it is likely that users would much
prefer write "kvm-arm.mode=nvhe", or "...=protected".
So here you go. This has the added advantage that we can now
always honor the "kvm-arm.mode=protected" option, even when
booting on a VHE system.

The VM management interfaces expose several VM operations to ACRN
userspace via ioctls. For example, creating VM, starting VM, destroying
VM and so on.
The ACRN Hypervisor needs to exchange data with the ACRN userspace
during the VM operations. HSM provides VM operation ioctls to the ACRN
userspace and communicates with the ACRN Hypervisor for VM operations
via hypercalls.
HSM maintains a list of User VM. Each User VM will be bound to an
existing file descriptor of /dev/acrn_hsm. The User VM will be
destroyed when the file descriptor is closed.

Add support for FS_VERITY_METADATA_TYPE_SIGNATURE to
FS_IOC_READ_VERITY_METADATA. This allows a userspace server program to
retrieve the built-in signature (if present) of a verity file for
serving to a client which implements fs-verity compatible verification.
See the patch which introduced FS_IOC_READ_VERITY_METADATA for more
details.
The ability for userspace to read the built-in signatures is also useful
because it allows a system that is using the in-kernel signature
verification to migrate to userspace signature verification.
This has been tested using a new xfstest which calls this ioctl via a
new subcommand for the 'fsverity' program from fsverity-utils.

Add support for FS_VERITY_METADATA_TYPE_DESCRIPTOR to

retrieve the fs-verity descriptor of a file for serving to a client
which implements fs-verity compatible verification. See the patch which
introduced FS_IOC_READ_VERITY_METADATA for more details.
"fs-verity descriptor" here means only the part that userspace cares
about because it is hashed to produce the file digest. It doesn't
include the signature which ext4 and f2fs append to the
fsverity_descriptor struct when storing it on-disk, since that way of
storing the signature is an implementation detail. The next patch adds
a separate metadata_type value for retrieving the signature separately.
This has been tested using a new xfstest which calls this ioctl via a
new subcommand for the 'fsverity' program from fsverity-utils.

Add an ioctl FS_IOC_READ_VERITY_METADATA which will allow reading verity
metadata from a file that has fs-verity enabled, including:
- The Merkle tree
- The fsverity_descriptor (not including the signature if present)
- The built-in signature, if present
This ioctl has similar semantics to pread(). It is passed the type of
metadata to read (one of the above three), and a buffer, offset, and
size. It returns the number of bytes read or an error.
Separate patches will add support for each of the above metadata types.
This patch just adds the ioctl itself.
This ioctl doesn't make any assumption about where the metadata is
stored on-disk. It does assume the metadata is in a stable format, but
that's basically already the case:
- The Merkle tree and fsverity_descriptor are defined by how fs-verity
file digests are computed; see the "File digest computation" section
of Documentation/filesystems/fsverity.rst. Technically, the way in
which the levels of the tree are ordered relative to each other wasn't
previously specified, but it's logical to put the root level first.
- The built-in signature is the value passed to FS_IOC_ENABLE_VERITY.
This ioctl is useful because it allows writing a server program that
takes a verity file and serves it to a client program, such that the
client can do its own fs-verity compatible verification of the file.
This only makes sense if the client doesn't trust the server and if the
server needs to provide the storage for the client.
More concretely, there is interest in using this ability in Android to
export APK files (which are protected by fs-verity) to "protected VMs".
This would use Protected KVM (https://lwn.net/Articles/836693), which
provides an isolated execution environment without having to trust the
traditional "host". A "guest" VM can boot from a signed image and
perform specific tasks in a minimum trusted environment using files that
have fs-verity enabled on the host, without trusting the host or
requiring that the guest has its own trusted storage.
Technically, it would be possible to duplicate the metadata and store it
in separate files for serving. However, that would be less efficient
and would require extra care in userspace to maintain file consistency.
In addition to the above, the ability to read the built-in signatures is
useful because it allows a system that is using the in-kernel signature
verification to migrate to userspace signature verification.

The bugfix mentioned there, commit b6c40d68ff ("net: only invoke
dev->change_rx_flags when device is UP"), was basically a "don't do
that" approach to working around the promiscuity while down issue.
Further work done by Vlad Yasevich in commit d2615bf450 ("net: core:
Always propagate flag changes to interfaces") has resolved the
underlying issue, and it is strictly up to the DSA and 8021q drivers
now, it is no longer mandated by the networking core that the master
interface must be up when changing its promiscuity.
From DSA's point of view, deciding to error out in dsa_slave_open
because the master isn't up is
(a) a bad user experience and
(b) knocking at an open door.
Even if there still was an issue with promiscuity while down, DSA could
still just open the master and avoid it.
Doing it this way has the additional benefit that user space can now
remove DSA-specific workarounds, like systemd-networkd with BindCarrier:
https://github.com/systemd/systemd/issues/7478
And we can finally remove one of the 2 bullets in the "Common pitfalls
using DSA setups" chapter.
Tested with two cascaded DSA switches:

According to the USB 3.2 spec, a SuperSpeed Plus device can operate at
gen2x2, gen2x1, or gen1x2. If the USB controller device supports
multiple lanes at different transfer rates, the user can specify the HW
capability via these new speed strings:
"super-speed-plus-gen2x2"
"super-speed-plus-gen2x1"
"super-speed-plus-gen1x2"
If the argument is simply "super-speed-plus", USB controllers should
default to their maximum transfer rate and number of lanes.

The V4L2 temporary clock helper API, was introduced
in late 2012 and, as mentioned in the documentation,
meant to be replaced by the generic clock API,
once the generic clock framework became available
on all relevant architectures.
The generic clock API is a well-established API (since a few
years now). The last few media capture drivers and sensors
using v4l2-clk have been converted to the generic clock framework.
We can now remove the v4l2-clk API.

Previously, a cross-reference to another document could only be created
by writing the full path to the document starting from the
Documentation/ directory.
Extend this to also allow relative paths to be used. A relative path
would be just the path, like ../filename.rst, while the absolute path
still needs to start from Documentation, like Documentation/filename.rst.
As part of this change, the .rst extension is now required for both
types of paths, since not requiring it would cause the regex to be too
generic.

Firmware/co-processors might use reserved memory areas in order to pass
data stemming from an nvmem device otherwise non accessible to Linux.
For example an EEPROM memory only physically accessible to firmware, or
data only accessible early at boot time.

Properties in if/then schemas weren't getting checked by the meta-schemas.
Enabling meta-schema checks finds several errors.
The use of an 'items' schema (as opposed to the list form) is wrong in
some cases as it applies to all entries. 'contains' is the correct schema
to use in the case of multiple entries.

encrypted through the KVM_SEV_LAUNCH_UPDATE_{DATA, VMSA} commands and
sign the report with the Platform Endorsement Key (PEK).
See the SEV FW API spec section 6.8 for more details.
Note there already exist a command (KVM_SEV_LAUNCH_MEASURE) that can be
used to get the SHA-256 digest. The main difference between the
KVM_SEV_LAUNCH_MEASURE and KVM_SEV_ATTESTATION_REPORT is that the latter
can be called while the guest is running and the measurement value is
signed with PEK.

Recent Intel Thunderbolt firmware connection manager has support for
another security level, SL5, that disables PCIe tunneling. This option
can be turned on from the BIOS.
When this is set the driver exposes a new security level "nopcie" to the
userspace and hides the authorized attribute under connected devices.
While there we also hide it when "dponly" security level is enabled
since it is not really usable in that case anyway.

Currently, when auto negotiation is on, the user can advertise all the
linkmodes which correspond to a specific speed, but does not have a
similar selector for the number of lanes. This is significant when a
specific speed can be achieved using different number of lanes. For
example, 2x50 or 4x25.
Add 'ETHTOOL_A_LINKMODES_LANES' attribute and expand 'struct
ethtool_link_settings' with lanes field in order to implement a new
lanes-selector that will enable the user to advertise a specific number
of lanes as well.
When auto negotiation is off, lanes parameter can be forced only if the
driver supports it. Add a capability bit in 'struct ethtool_ops' that
allows ethtool know if the driver can handle the lanes parameter when
auto negotiation is off, so if it does not, an error message will be
returned when trying to set lanes.
Example:
$ ethtool -s swp1 lanes 4
$ ethtool swp1

We've added a new mount options, "checkpoint_merge" and "nocheckpoint_merge",
which creates a kernel daemon and makes it to merge concurrent checkpoint
requests as much as possible to eliminate redundant checkpoint issues. Plus,
we can eliminate the sluggish issue caused by slow checkpoint operation
when the checkpoint is done in a process context in a cgroup having
low i/o budget and cpu shares. To make this do better, we set the
default i/o priority of the kernel daemon to "3", to give one higher
priority than other kernel threads. The below verification result
explains this.
The basic idea has come from https://opensource.samsung.com.

The Meson8/Meson8b/Meson8m2 SoCs have a register bank called SECBUS2 which
contains registers for various IP blocks such as pin-controller bits for
the BSD_EN and TEST_N GPIOs as well as some AO ARC core control bits.
The registers can be accessed directly when not running in "secure mode".
When "secure mode" is enabled then these registers have to be accessed
through secure monitor calls.
So far these SoCs are always known to boot in "non-secure mode".
Add a binding documentation using syscon (as these registers are shared
across different IPs) for the SECBUS2 registers.

Increase the parallelism level for pwork clients to the workqueue

a large factor, and the following posteof/cowblocks cleanup series will
use the functionality presented in this patch to run garbage collection
as quickly as possible.
We do this by switching the pwork workqueue to unbounded, since the
current user (quotacheck) runs lengthy scans for each work item and we
don't care about dispatching the work on a warm cpu cache or anything
like that. Also set WQ_SYSFS so that we can monitor where the wq is
