When pre-calibration data is missing, do not fail the driver probe.
Instead, just print a warning and fall back to regular calibration.

Add pre-calibration for mt7986 and mt7916. It has different data size
with mt7915. Group cal needs 54k and 94k for 2G + 5G and 2G + 6G,
respectively. DPD cal needs 300k.

When queueing packets, only the MT76_RESET flag of the primary PHY
is checked. If the primary PHY is scanning or changing channels, this can
lead to packet loss for tx on the second PHY.
Fix this by passing the phy to the .tx_queue_skb op and using it to check
the correct flag.

"- Enable CPPC v2 for certain processors in the family 17H, as requested
by TR40 processor users who expect improved performance and lower
system temperature.
- Change latency and delay values to be read from platform firmware
firstly for more accurate timing.
- A new quirk is introduced for supporting amd-pstate on legacy
processors which either lack CPPC capability, or only only have CPPC
v2 capability."

Currently, when using WCN7850 or QCN9274 as AP, ath12k always performs down
grade phy mode operation regardless of whether the firmware supports EHT
capability or not and then vdev will start in HE mode. When stations that
support EHT capability try to connect to the AP, the AP will set phy mode
to EHT after receiving the association request packet, and then send
WMI_PEER_ASSOC_CMDID command to firmware, AP’s firmware will crash.
This is because when the ath12k_mac_copy_sband_iftype_data() function
handles EHT capability, it does not copy the EHT capability into the
iftype[band][type] array according to the interface type. So, interface
type should not be used as an index to get eht_cap in
ath12k_mac_check_down_grade_phy_mode() function.
To address this issue, use types_mask to select the eht_cap in
ath12k_mac_check_down_grade_phy_mode() function.
This patch affects QCN9274 and WCN7850 because they have the same issue.

The J2 SPI controller bindings never allowed spi-max-frequency property
in the controller node. Neither old spi-bus.txt bindings, nor new DT
schema allows it. Linux driver does not parse that property from
controller node, thus drop it from DTS as incorrect hardware
description. The SPI child device has already the same property with
the same value, so functionality should not be affected.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The following commits loosened the permissions of /proc/<PID>/fdinfo/
directory, as well as the files within it, from 0500 to 0555 while also
introducing a PTRACE_MODE_READ check between the current task and
<PID>'s task:
- commit 7bc3fa0172a4 ("procfs: allow reading fdinfo with PTRACE_MODE_READ")
- commit 1927e498aee1 ("procfs: prevent unprivileged processes accessing fdinfo dir")
Before those changes, inode based system calls like inotify_add_watch(2)
would fail when the current task didn't have sufficient read permissions:
[...]
lstat("/proc/1/task/1/fdinfo", {st_mode=S_IFDIR|0500, st_size=0, ...}) = 0
inotify_add_watch(64, "/proc/1/task/1/fdinfo",
IN_MODIFY|IN_ATTRIB|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|
IN_ONLYDIR|IN_DONT_FOLLOW|IN_EXCL_UNLINK) = -1 EACCES (Permission denied)
[...]
This matches the documented behavior in the inotify_add_watch(2) man
page:
ERRORS
EACCES Read access to the given file is not permitted.
After those changes, inotify_add_watch(2) started succeeding despite the
current task not having PTRACE_MODE_READ privileges on the target task:
[...]
lstat("/proc/1/task/1/fdinfo", {st_mode=S_IFDIR|0555, st_size=0, ...}) = 0
inotify_add_watch(64, "/proc/1/task/1/fdinfo",
IN_MODIFY|IN_ATTRIB|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|
IN_ONLYDIR|IN_DONT_FOLLOW|IN_EXCL_UNLINK) = 1757
openat(AT_FDCWD, "/proc/1/task/1/fdinfo",
O_RDONLY|O_NONBLOCK|O_CLOEXEC|O_DIRECTORY) = -1 EACCES (Permission denied)
[...]
This change in behavior broke .NET prior to v7. See the github link
below for the v7 commit that inadvertently/quietly (?) fixed .NET after
the kernel changes mentioned above.
Return to the old behavior by moving the PTRACE_MODE_READ check out of
the file .open operation and into the inode .permission operation:
[...]
lstat("/proc/1/task/1/fdinfo", {st_mode=S_IFDIR|0555, st_size=0, ...}) = 0
inotify_add_watch(64, "/proc/1/task/1/fdinfo",
IN_MODIFY|IN_ATTRIB|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|
IN_ONLYDIR|IN_DONT_FOLLOW|IN_EXCL_UNLINK) = -1 EACCES (Permission denied)

ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull netfs writeback updates from David Howells:
The primary purpose of these patches is to rework the netfslib writeback
implementation such that pages read from the cache are written to the cache
through ->writepages(), thereby allowing the fscache page flag to be
retired.
The reworking also:
(1) builds on top of the new writeback_iter() infrastructure;
(2) makes it possible to use vectored write RPCs as discontiguous streams
of pages can be accommodated;
(3) makes it easier to do simultaneous content crypto and stream division.
(4) provides support for retrying writes and re-dividing a stream;
(5) replaces the ->launder_folio() op, so that ->writepages() is used
instead;
(6) uses mempools to allocate the netfs_io_request and netfs_io_subrequest
structs to avoid allocation failure in the writeback path.
Some code that uses the fscache page flag is retained for compatibility
purposes with nfs and ceph. The code is switched to using the synonymous
private_2 label instead and marked with deprecation comments. I have a
separate set of patches that convert cifs to use this code.
-~-
In this new implementation, writeback_iter() is used to pump folios,
progressively creating two parallel, but separate streams. Either or both
streams can contain gaps, and the subrequests in each stream can be of
variable size, don't need to align with each other and don't need to align
with the folios. (Note that more streams can be added if we have multiple
servers to duplicate data to).
Indeed, subrequests can cross folio boundaries, may cover several folios or
a folio may be spanned by multiple subrequests, e.g.:
+---+---+-----+-----+---+----------+
Folios: | | | | | | |
+---+---+-----+-----+---+----------+
+------+------+ +----+----+
Upload: | | |.....| | |
+------+------+ +----+----+
+------+------+------+------+------+
Cache: | | | | | |
+------+------+------+------+------+
Data that got read from the server that needs copying to the cache is
stored in folios that are marked dirty and have folio->private set to a
special value.
The progressive subrequest construction permits the algorithm to be
preparing both the next upload to the server and the next write to the
cache whilst the previous ones are already in progress. Throttling can be
applied to control the rate of production of subrequests - and, in any
case, we probably want to write them to the server in ascending order,
particularly if the file will be extended.
Content crypto can also be prepared at the same time as the subrequests and
run asynchronously, with the prepped requests being stalled until the
crypto catches up with them. This might also be useful for transport
crypto, but that happens at a lower layer, so probably would be harder to
pull off.
The algorithm is split into three parts:
(1) The issuer. This walks through the data, packaging it up, encrypting
it and creating subrequests. The part of this that generates
subrequests only deals with file positions and spans and so is usable
for DIO/unbuffered writes as well as buffered writes.
(2) The collector. This asynchronously collects completed subrequests,
unlocks folios, frees crypto buffers and performs any retries. This
runs in a work queue so that the issuer can return to the caller for
writeback (so that the VM can have its kswapd thread back) or async
writes.
Collection is slightly complex as the collector has to work out where
discontiguities happen in the folio list so that it doesn't try and
collect folios that weren't included in the write out.
(3) The retryer. This pauses the issuer, waits for all outstanding
subrequests to complete and then goes through the failed subrequests
to reissue them. This may involve reprepping them (with cifs, the
credits must be renegotiated and a subrequest may need splitting), and
doing RMW for content crypto if there's a conflicting change on the
server.
