This reverts commit 1a48dd7b9ac809d1bd0fd2fef509abba83433846.
A recent change enabling OTG mode on the Lenovo ThinkPad T14s USB-C
ports can break SuperSpeed device hotplugging. The host controller is
enumerated, but the device is not:
xhci-hcd xhci-hcd.5.auto: xHCI Host Controller
xhci-hcd xhci-hcd.5.auto: new USB bus registered, assigned bus number 3
xhci-hcd xhci-hcd.5.auto: hcc params 0x0110ffc5 hci version 0x110 quirks 0x000080a000000810
xhci-hcd xhci-hcd.5.auto: irq 247, io mem 0x0a800000
xhci-hcd xhci-hcd.5.auto: xHCI Host Controller
xhci-hcd xhci-hcd.5.auto: new USB bus registered, assigned bus number 4
xhci-hcd xhci-hcd.5.auto: Host supports USB 3.1 Enhanced SuperSpeed
hub 3-0:1.0: USB hub found
hub 3-0:1.0: 1 port detected
hub 4-0:1.0: USB hub found
hub 4-0:1.0: 1 port detected
Once this happens on either of the two ports, no amount of disconnecting
and reconnecting makes the SuperSpeed device be enumerated, while
FullSpeed device enumeration still works.
With retimer (and orientation detection) support not even merged yet,
let's revert at least until we have stable host mode in mainline.

The macros giving the direction of the crossing thresholds use the BIT
macro which is not exported to the userspace. Consequently when an
userspace program includes the header, it fails to compile.
Replace the macros by their litteral to allow the compilation of
userspace program using this header.

32 IDs should be plenty (at yet, not too greedy) since a lot of sample
drivers will use their own subsystem allocations.
Sample drivers predominately reside in <KERNEL_ROOT>/samples, but there

There are situations where a pointer to a `struct device` will become
necessary (e.g. for calling into dev_*() functions). This accessor
allows callers to pull this out from the `struct miscdevice`.

Providing access to the underlying `struct miscdevice` is useful for
various reasons. For example, this allows you access the miscdevice's
internal `struct device` for use with the `dev_*` printing macros.
Note that since the underlying `struct miscdevice` could get freed at
any point after the fops->open() call (if misc_deregister is called),
only the open call is given access to it. To use `dev_*` printing macros
from other fops hooks, take a refcount on `miscdevice->this_device` to
keep it alive. See the linked thread for further discussion on the
lifetime of `struct miscdevice`.

This allows fops to access information about the underlying struct file

For many use cases (e.g. container images are just fetched from remote),
performance will be impacted if underlay page cache is up-to-date but
direct i/o flushes dirty pages first.
Instead, let's use buffered I/O by default to keep in sync with loop
devices and add a (re)mount option to explicitly give a try to use
direct I/O if supported by the underlying files.
The container startup time is improved as below:

Alexandre observed a warning emitted from pci_msi_setup_msi_irqs() on a
RISCV platform which does not provide PCI/MSI support:
WARNING: CPU: 1 PID: 1 at drivers/pci/msi/msi.h:121 pci_msi_setup_msi_irqs+0x2c/0x32
__pci_enable_msix_range+0x30c/0x596
pci_msi_setup_msi_irqs+0x2c/0x32
pci_alloc_irq_vectors_affinity+0xb8/0xe2
RISCV uses hierarchical interrupt domains and correctly does not implement
the legacy fallback. The warning triggers from the legacy fallback stub.
That warning is bogus as the PCI/MSI layer knows whether a PCI/MSI parent
domain is associated with the device or not. There is a check for MSI-X,
which has a legacy assumption. But that legacy fallback assumption is only
valid when legacy support is enabled, but otherwise the check should simply
return -ENOTSUPP.
Loongarch tripped over the same problem and blindly enabled legacy support
without implementing the legacy fallbacks. There are weak implementations
which return an error, so the problem was papered over.
Correct pci_msi_domain_supports() to evaluate the legacy mode and add
the missing supported check into the MSI enable path to complete it.

When USB-C monitor is connected directly to Intel Barlow Ridge host, it
goes into "redrive" mode that basically routes the DisplayPort signals
directly from the GPU to the USB-C monitor without any tunneling needed.
However, the host router must be powered on for this to work. Aaron
reported that there are a couple of cases where this will not work with
the current code:
- Booting with USB-C monitor plugged in.
- Plugging in USB-C monitor when the host router is in sleep state
(runtime suspended).
- Plugging in USB-C device while the system is in system sleep state.
In all these cases once the host router is runtime suspended the picture
on the connected USB-C display disappears too. This is certainly not
what the user expected.
For this reason improve the redrive mode handling to keep the host
router from runtime suspending when detect that any of the above cases
is happening.

Since commit 0a77d947f599 ("ksmbd: check outstanding simultaneous SMB
operations"), ksmbd enforces a maximum number of simultaneous operations
for a connection. The problem is that reaching the limit causes ksmbd to
close the socket, and the client has no indication that it should have
slowed down.
This behaviour can be reproduced by setting "smb2 max credits = 128" (or
lower), and transferring a large file (25GB).
smbclient fails as below:
$ smbclient //192.168.1.254/testshare -U user%pass
smb: \> put file.bin
cli_push returned NT_STATUS_USER_SESSION_DELETED
putting file file.bin as \file.bin smb2cli_req_compound_submit:
Insufficient credits. 0 available, 1 needed
NT_STATUS_INTERNAL_ERROR closing remote file \file.bin
smb: \> smb2cli_req_compound_submit: Insufficient credits. 0 available,
1 needed
Windows clients fail with 0x8007003b (with smaller files even).
Fix this by delaying reading from the socket until there's room to
allocate a request. This effectively applies backpressure on the client,
so the transfer completes, albeit at a slower rate.

The existing linked list based implementation of how ts tags are
assigned and managed is unsafe against concurrency and corner cases:
- element addition in tx processing can race against element removal
in ts queue completion,
- element removal in ts queue completion can race against element
removal in device close,
- if a large number of frames gets added to tx queue without ts queue
completions in between, elements with duplicate tag values can get
added.
Use a different implementation, based on per-port used tags bitmaps and
saved skb arrays.
Safety for addition in tx processing vs removal in ts completion is
provided by:
tag = find_first_zero_bit(...);
smp_mb();
<write rdev->ts_skb[tag]>
set_bit(...);
vs
<read rdev->ts_skb[tag]>
smp_mb();
clear_bit(...);
Safety for removal in ts completion vs removal in device close is
provided by using atomic read-and-clear for rdev->ts_skb[tag]:
ts_skb = xchg(&rdev->ts_skb[tag], NULL);
if (ts_skb)
<handle it>

There are some FW error handling paths that can cause us to
try to destroy the workqueue more than once, so let's be sure
we're checking for that.
The case where this popped up was in an AER event where the
handlers got called in such a way that ionic_reset_prepare()
and thus ionic_dev_teardown() got called twice in a row.
The second time through the workqueue was already destroyed,
and destroy_workqueue() choked on the bad wq pointer.
We didn't hit this in AER handler testing before because at
that time we weren't using a private workqueue. Later we
replaced the use of the system workqueue with our own private
workqueue but hadn't rerun the AER handler testing since then.

Use the correct attribute space for sub-message key lookup in nested

key and "data" sub-message are nested attributes in "linkinfo".

--create \
--spec Documentation/netlink/specs/rt_link.yaml \

Packets injected by the CPU should have a SRC_PORT field equal to the
CPU port module index in the Analyzer block (ocelot->num_phys_ports).
The blamed commit copied the ocelot_ifh_set_basic() call incorrectly
from ocelot_xmit_common() in net/dsa/tag_ocelot.c. Instead of calling
with "x", it calls with BIT_ULL(x), but the field is not a port mask,
but rather a single port index.
[ side note: this is the technical debt of code duplication :( ]
The error used to be silent and doesn't appear to have other
user-visible manifestations, but with new changes in the packing
library, it now fails loudly as follows:
------------[ cut here ]------------

The code path pertains to the ocelot switchdev driver and to the felix
