This reverts commit 398aa9a7e77cf23c2a6f882ddd3dcd96f21771dc.
The update to the gadget API to support EBC feature is incomplete. It's
missing at least the following:
* New usage documentation
* Gadget capability check
* Condition for the user to check how many and which endpoints can be
used as "fifo_mode"
* Description of how it can affect completed request (e.g. dwc3 won't
update TRB on completion -- ie. how it can affect request's actual
length report)
Let's revert this until it's ready.

If intending to associate with a lower bandwidth, remove capabilities
related to 320 MHz from the EHT capabilities element. Also change the
EHT MCS-NSS set accordingly: if just reducing 320->160 or similar the
format doesn't change, just cut off the last bytes. If changing from
higher bandwidth to 20 MHz only EHT STA, adjust the format.
Note that this also requires adjusting the caller in mlme.c since the
data written can now be shorter than it determined. We need to clean
all that up. Since the other callers pass NULL for the conn limit, we
don't need to change things there.

A short read may occur while reading the message footer from the
socket. Later, when the socket is ready for another read, the
messenger invokes all read_partial_*() handlers, including
read_partial_sparse_msg_data(). The expectation is that
read_partial_sparse_msg_data() would bail, allowing the messenger to
invoke read_partial() for the footer and pick up where it left off.
However read_partial_sparse_msg_data() violates that and ends up
calling into the state machine in the OSD client. The sparse-read
state machine assumes that it's a new op and interprets some piece of
the footer as the sparse-read header and returns bogus extents/data
length, etc.
To determine whether read_partial_sparse_msg_data() should bail, let's
reuse cursor->total_resid. Because once it reaches to zero that means
all the extents and data have been successfully received in last read,
else it could break out when partially reading any of the extents and
data. And then osd_sparse_read() could continue where it left off.

The detection of dirty-throttled tasks in blk-wbt has been subtly broken
since its beginning in 2016. Namely if we are doing cgroup writeback and
the throttled task is not in the root cgroup, balance_dirty_pages() will
set dirty_sleep for the non-root bdi_writeback structure. However
blk-wbt checks dirty_sleep only in the root cgroup bdi_writeback
structure. Thus detection of recently throttled tasks is not working in
this case (we noticed this when we switched to cgroup v2 and suddently
writeback was slow).
Since blk-wbt has no easy way to get to proper bdi_writeback and
furthermore its intention has always been to work on the whole device
rather than on individual cgroups, just move the dirty_sleep timestamp
from bdi_writeback to backing_dev_info. That fixes the checking for
recently throttled task and saves memory for everybody as a bonus.

commit dfad37051ade ("remap_range: move permission hooks out of
do_clone_file_range()") moved the permission hooks from
do_clone_file_range() out to its caller vfs_clone_file_range(),
but left all the fast sanity checks in do_clone_file_range().
This makes the expensive security hooks be called in situations
that they would not have been called before (e.g. fs does not support
clone).
The only reason for the do_clone_file_range() helper was that overlayfs
did not use to be able to call vfs_clone_file_range() from copy up
context with sb_writers lock held. However, since commit c63e56a4a652
("ovl: do not open/llseek lower file with upper sb_writers held"),
overlayfs just uses an open coded version of vfs_clone_file_range().
Merge_clone_file_range() into vfs_clone_file_range(), restoring the
original order of checks as it was before the regressing commit and adapt
the overlayfs code to call vfs_clone_file_range() before the permission
hooks that were added by commit ca7ab482401c ("ovl: add permission hooks
outside of do_splice_direct()").
Note that in the merge of do_clone_file_range(), the file_start_write()
context was reduced to cover ->remap_file_range() without holding it
over the permission hooks, which was the reason for doing the regressing
commit in the first place.

The hrtimers migration on CPU-down hotplug process has been moved
earlier, before the CPU actually goes to die. This leaves a small window
of opportunity to queue an hrtimer in a blind spot, leaving it ignored.
For example a practical case has been reported with RCU waking up a
SCHED_FIFO task right before the CPUHP_AP_IDLE_DEAD stage, queuing that
way a sched/rt timer to the local offline CPU.
Make sure such situations never go unnoticed and warn when that happens.

The CW1200 uses two GPIOs to control the powerup and reset
pins, get these from GPIO descriptors instead of being passed
as platform data from boardfiles.
The RESET line will need to be marked as active low as we will
let gpiolib handle the polarity inversion.
The SDIO case is a bit special since the "card" need to be
powered up before it gets detected on the SDIO bus and
properly probed. Fix this by using board-specific GPIOs
assigned to device "NULL".

Aligning the buffer to the L1 cache is not sufficient in some platforms
as they might have larger cacheline sizes for caches after L1 and thus,
we can't guarantee DMA safety.
That was the whole reason to introduce IIO_DMA_MINALIGN in [1]. Do the same
for st_sensors common buffer.
While at it, moved the odr_lock before buffer_data as we definitely
don't want any other data to share a cacheline with the buffer.

When the width of a fill is smaller than the width of the preceding
spill, the information about scalar boundaries can still be preserved,
as long as it's coerced to the right width (done by coerce_reg_to_size).
Even further, if the actual value fits into the fill width, the ID can
be preserved as well for further tracking of equal scalars.
Implement the above improvements, which makes narrowing fills behave the
same as narrowing spills and MOVs between registers.
Two tests are adjusted to accommodate for endianness differences and to
take into account that it's now allowed to do a narrowing fill from the
least significant bits.
reg_bounds_sync is added to coerce_reg_to_size to correctly adjust
umin/umax boundaries after the var_off truncation, for example, a 64-bit
value 0xXXXXXXXX00000000, when read as a 32-bit, gets umin = 0, umax =
0xFFFFFFFF, var_off = (0x0; 0xffffffff00000000), which needs to be
synced down to umax = 0, otherwise reg_bounds_sanity_check doesn't pass.

Pablo Neira Ayuso says:
====================
Netfilter fixes for net
1) TCP conntrack now only evaluates window negotiation for packets in
the REPLY direction, from Ryan Schaefer. Otherwise SYN retransmissions
trigger incorrect window scale negotiation. From Ryan Schaefer.
2) Restrict tunnel objects to NFPROTO_NETDEV which is where it makes sense
to use this object type.
3) Fix conntrack pick up from the middle of SCTP_CID_SHUTDOWN_ACK packets.
From Xin Long.
4) Another attempt from Jozsef Kadlecsik to address the slow down of the
swap command in ipset.
5) Replace a BUG_ON by WARN_ON_ONCE in nf_log, and consolidate check for
the case that the logger is NULL from the read side lock section.
6) Address lack of sanitization for custom expectations. Restrict layer 3
and 4 families to what it is supported by userspace.

The patch "netfilter: ipset: fix race condition between swap/destroy
and kernel side add/del/test", commit 28628fa9 fixes a race condition.
But the synchronize_rcu() added to the swap function unnecessarily slows
it down: it can safely be moved to destroy and use call_rcu() instead.
Eric Dumazet pointed out that simply calling the destroy functions as
rcu callback does not work: sets with timeout use garbage collectors
which need cancelling at destroy which can wait. Therefore the destroy
functions are split into two: cancelling garbage collectors safely at
executing the command received by netlink and moving the remaining
part only into the rcu callback.

This commit adds support for flags on BTF_SET8s. struct btf_id_set8
already supported 32 bits worth of flags, but was only used for
alignment purposes before.
We now use these bits to encode flags. The first use case is tagging
kfunc sets with a flag so that pahole can recognize which
BTF_ID_FLAGS(func, ..) are actual kfuncs.

A last minute revert in 6.7-final introduced a potential deadlock when
enabling ASPM during probe of Qualcomm PCIe controllers as reported by
lockdep:
============================================
WARNING: possible recursive locking detected
6.7.0 #40 Not tainted
--------------------------------------------
kworker/u16:5/90 is trying to acquire lock:
ffffacfa78ced000 (pci_bus_sem){++++}-{3:3}, at: pcie_aspm_pm_state_change+0x58/0xdc
but task is already holding lock:
ffffacfa78ced000 (pci_bus_sem){++++}-{3:3}, at: pci_walk_bus+0x34/0xbc
other info that might help us debug this:
Possible unsafe locking scenario:

lock(pci_bus_sem);
*** DEADLOCK ***

The deadlock can easily be reproduced on machines like the Lenovo ThinkPad
X13s by adding a delay to increase the race window during asynchronous
probe where another thread can take a write lock.
Add a new pci_set_power_state_locked() and associated helper functions that
can be called with the PCI bus semaphore held to avoid taking the read lock
twice.

This patch changes the following in struct ethtool_keee
- remove member cmd, it's not needed on kernel side
- remove reserved fields
- switch the semantically boolean members to type bool
We don't have to change any user of the boolean members due to the
implicit casting from/to bool. A small change is needed where a
pointer to bool members is used, in addition remove few now unneeded
double negations.

In order to pass EEE link modes beyond bit 32 to userspace we have to
complement the 32 bit bitmaps in struct ethtool_eee with linkmode
bitmaps. Therefore, similar to ethtool_link_settings and
ethtool_link_ksettings, add a struct ethtool_keee. In a first step
it's an identical copy of ethtool_eee. This patch simply does a
s/ethtool_eee/ethtool_keee/g for all users.
No functional change intended.

Follow the docs at Documentation/bpf/kfuncs.rst:
- declare the function with `__bpf_kfunc`
- disables missing prototype warnings, which allows to remove them from
include/linux/hid-bpf.h
Removing the prototypes is not an issue because we currently have to
redeclare them when writing the BPF program. They will eventually be
generated by bpftool directly AFAIU.
