It was reported that on "HP ENVY x360" that power LED does not come
back, certain keys like brightness controls do not work, and the fan
never spins up, even under load on 5.14 final.
In analysis of the SSDT it's clear that the Microsoft UUID doesn't
provide functional support, but rather the AMD UUID should be
supporting this system.
Because this is a gap in the expected logic, we checked back with
internal team. The conclusion was that on Windows AMD uPEP *does*
run even when Microsoft UUID present, but most OEM systems have
adopted value of "0x3" for supported functions and hence nothing
runs.
Henceforth add support for running both Microsoft and AMD methods.
This approach will also allow the same logic on Intel systems if
desired at a future time as well by pulling the evaluation of
`lps0_dsm_func_mask_microsoft` out of the `if` block for
`acpi_s2idle_vendor_amd`.

Pull erofs updates from Gao Xiang:
"In this cycle, direct I/O and fsdax support for uncompressed files are
now added in order to avoid double-caching for loop device and VM
container use cases. All uncompressed cases are now turned into iomap
infrastructure, which looks much simpler and cleaner.
In addition, fiemap support is added for both (un)compressed files by
using iomap infrastructure as well so end users can easily get file
distribution. We've also added chunk-based uncompressed files support
for data deduplication as the next step of VM container use cases.

On some systems, in order to get to the deepest low-power state of
the platform (which may be necessary to save significant enough
amounts of energy while suspended to idle. for example), devices on
the PCI bus exposed by the VMD driver need to be power-managed via
ACPI. However, the layout of the ACPI namespace below the VMD
controller device object does not reflect the layout of the PCI bus
under the VMD host bridge, so in order to identify the ACPI companion
objects for the devices on that bus, it is necessary to use a special
_ADR encoding on the ACPI side. In other words, acpi_pci_find_companion()
does not work for these devices, so it needs to be amended with a
special lookup logic specific to the VMD bus.
Address this issue by allowing the VMD driver to temporarily install
an ACPI companion lookup hook containing the code matching the devices
on the VMD PCI bus with the corresponding objects in the ACPI
namespace.

If the call to ext4_map_blocks() fails due to an corrupted file
system, ext4_ext_replay_set_iblocks() can get stuck in an infinite
loop. This could be reproduced by running generic/526 with a file
system that has inline_data and fast_commit enabled. The system will
repeatedly log to the console:
EXT4-fs warning (device dm-3): ext4_block_to_path:105: block 1074800922 > max in inode 131076
and the stack that it gets stuck in is:
ext4_block_to_path+0xe3/0x130
ext4_ind_map_blocks+0x93/0x690

With this patch, generic/526 still fails, but system is no longer
locking up in a tight loop. It's likely the root casue is that
fast_commit replay is corrupting file systems with inline_data, and we
probably need to add better error handling in the fast commit replay
code path beyond what is done here, which essentially just breaks the
infinite loop without reporting the to the higher levels of the code.

Commit e26f023e01 ("firmware/dmi: Include product_sku info to modalias")
added a new field to the modalias in the middle of the modalias, breaking
some existing udev/hwdb matches on the whole modalias without a wildcard
('*') in between the pvr and rvn fields.
All modalias matches in e.g. :
https://github.com/systemd/systemd/blob/main/hwdb.d/60-sensor.hwdb
deliberately end in ':*' so that new fields can be added at *the end* of
the modalias, but adding a new field in the middle like this breaks things.
Move the new sku field to the end of the modalias to fix some hwdb
entries no longer matching.
The new sku field has already been put to use in 2 new hwdb entries:
sensor:modalias:platform:HID-SENSOR-200073:dmi:*svnDell*:sku0A3E:*
ACCEL_LOCATION=base
sensor:modalias:platform:HID-SENSOR-200073:dmi:*svnDell*:sku0B0B:*
ACCEL_LOCATION=base
The wildcard use before and after the sku in these matches means that they
should keep working with the sku moved to the end.
Note that there is a second instance of in essence the same problem,
commit f5152f4ded ("firmware/dmi: Report DMI Bios & EC firmware release")
Added 2 new br and efr fields in the middle of the modalias. This too
breaks some hwdb modalias matches, but this has gone unnoticed for over
a year. So some newer hwdb modalias matches actually depend on these
fields being in the middle of the string. Moving these to the end now
would break 3 hwdb entries, while fixing 8 entries.
Since there is no good answer for the new br and efr fields I have chosen
to leave these as is. Instead I'll submit a hwdb update to put a wildcard
at the place where these fields may or may not be present depending on the
kernel version.

Pull xfs updates from Darrick Wong:
"There's a lot in this cycle.
Starting with bug fixes: To avoid livelocks between the logging code
and the quota code, we've disabled the ability of quotaoff to turn off
quota accounting. (Admins can still disable quota enforcement, but
truly turning off accounting requires a remount.) We've tried to do
this in a careful enough way that there shouldn't be any user visible
effects aside from quotaoff no longer randomly hanging the system.
We've also fixed some bugs in runtime log behavior that could trip up
log recovery if (otherwise unrelated) transactions manage to start and
commit concurrently; some bugs in the GETFSMAP ioctl where we would
incorrectly restrict the range of records output if the two xfs
devices are of different sizes; a bug that resulted in fallocate
funshare failing unnecessarily; and broken behavior in the xfs inode
cache when DONTCACHE is in play.
As for new features: we now batch inode inactivations in percpu
background threads, which sharply decreases frontend thread wait time
when performing file deletions and should improve overall directory
tree deletion times. This eliminates both the problem where closing an
unlinked file (especially on a frozen fs) can stall for a long time,
and should also ease complaints about direct reclaim bogging down on
unlinked file cleanup.
Starting with this release, we've enabled pipelining of the XFS log.
On workloads with high rates of metadata updates to different shards
of the filesystem, multiple threads can be used to format committed
log updates into log checkpoints.
Lastly, with this release, two new features have graduated to
supported status: inode btree counters (for faster mounts), and
support for dates beyond Y2038. Expect these to be enabled by default
in a future release of xfsprogs.
Summary:
- Fix a potential log livelock on busy filesystems when there's so
much work going on that we can't finish a quotaoff before filling
up the log by removing the ability to disable quota accounting.
- Introduce the ability to use per-CPU data structures in XFS so that
we can do a better job of maintaining CPU locality for certain
operations.
- Defer inode inactivation work to per-CPU lists, which will help us
batch that processing. Deletions of large sparse files will
*appear* to run faster, but all that means is that we've moved the
work to the backend.
- Drop the EXPERIMENTAL warnings from the y2038+ support and the
inode btree counters, since it's been nearly a year and no
complaints have come in.
- Remove more of our bespoke kmem* variants in favor of using the
standard Linux calls.
- Prepare for the addition of log incompat features in upcoming
cycles by actually adding code to support this.
- Small cleanups of the xattr code in preparation for landing support
for full logging of extended attribute updates in a future cycle.
- Replace the various log shutdown state and flag code all over xfs
with a single atomic bit flag.
- Fix a serious log recovery bug where log item replay can be skipped
based on the start lsn of a transaction even though the transaction
commit lsn is the key data point for that by enforcing start lsns
to appear in the log in the same order as commit lsns.
- Enable pipelining in the code that pushes log items to disk.
- Drop ->writepage.
- Fix some bugs in GETFSMAP where the last fsmap record reported for
a device could extend beyond the end of the device, and a separate
bug where query keys for one device could be applied to another.
- Don't let GETFSMAP query functions edit their input parameters.
- Small cleanups to the scrub code's handling of perag structures.
- Small cleanups to the incore inode tree walk code.
- Constify btree function parameters that aren't changed, so that
there will never again be confusion about range query functions
changing their input parameters.
- Standardize the format and names of tracepoint data attributes.
- Clean up all the mount state and feature flags to use wrapped
bitset functions instead of inconsistently open-coded flag checks.
- Fix some confusion between xfs_buf hash table key variable vs.
block number.
- Fix a mis-interaction with iomap where we reported shared delalloc
cow fork extents to iomap, which would cause the iomap unshare
operation to return IO errors unnecessarily.
- Fix DONTCACHE behavior"

The function bfq_setup_merge prepares the merging between two
bfq_queues, say bfqq and new_bfqq. To this goal, it assigns
bfqq->new_bfqq = new_bfqq. Then, each time some I/O for bfqq arrives,
the process that generated that I/O is disassociated from bfqq and
associated with new_bfqq (merging is actually a redirection). In this
respect, bfq_setup_merge increases new_bfqq->ref in advance, adding
the number of processes that are expected to be associated with
new_bfqq.
Unfortunately, the stable-merging mechanism interferes with this
setup. After bfqq->new_bfqq has been set by bfq_setup_merge, and
before all the expected processes have been associated with
bfqq->new_bfqq, bfqq may happen to be stably merged with a different
queue than the current bfqq->new_bfqq. In this case, bfqq->new_bfqq
gets changed. So, some of the processes that have been already
accounted for in the ref counter of the previous new_bfqq will not be
associated with that queue. This creates an unbalance, because those
references will never be decremented.
This commit fixes this issue by reestablishing the previous, natural
behaviour: once bfqq->new_bfqq has been set, it will not be changed
until all expected redirections have occurred.

have 9 ports (port 6 being inactive) and they use port 5 as CPU by
default (depending on design some other may be CPU ports too).
A more reliable way of determining number of ports is to check for the
last set bit in the "enabled_ports" bitfield.
This fixes b53 internal state, it will allow providing accurate info to

I don't think we need to call flowi{4,6}_to_flowi() from these functions
because the first member of "struct flowi4" and "struct flowi6" is
struct flowi_common __fl_common;
while the first member of "struct flowi" is
union {
struct flowi_common __fl_common;
struct flowi4 ip4;
struct flowi6 ip6;
struct flowidn dn;
} u;
which should point to the same address without access to "struct flowi".

Currently, outgoing packets larger than 1496 bytes are dropped when
tagged VLAN is used on a switch port.
Add the frame check sequence length to the value of the register
GSWIP_MAC_FLEN to fix this. This matches the lantiq_ppa vendor driver,
which uses a value consisting of 1518 bytes for the MAC frame, plus the
lengths of special tag and VLAN tags.

Starting with following patch MIPS Malta is not able to boot:
| commit 79edff1206
| Author: Rob Herring <robh@kernel.org>
| scripts/dtc: Update to upstream version v1.6.0-51-g183df9e9c2b9
The reason is the alignment test added to the fdt_ro_probe_(). To fix
this issue, we need to make sure that fdt_buf is aligned.
Since the dtc patch was designed to uncover potential issue, I handle
initial MIPS Malta patch as initial bug.

Pull printk updates from Petr Mladek:
- Optionally, provide an index of possible printk messages via
<debugfs>/printk/index/. It can be used when monitoring important
kernel messages on a farm of various hosts. The monitor has to be
updated when some messages has changed or are not longer available by
a newly deployed kernel.
- Add printk.console_no_auto_verbose boot parameter. It allows to
generate crash dump even with slow consoles in a reasonable time
frame.
- Remove printk_safe buffers. The messages are always stored directly
to the main logbuffer, even in NMI or recursive context. Also it
allows to serialize syslog operations by a mutex instead of a spin
lock.
- Misc clean up and build fixes.
