In __bond_release_one(), bond_set_carrier() is only called when bond
device has no slave. Therefore, if we remove the up slave from a master
with two slaves and keep the down slave, the master will remain up.
Fix this by moving bond_set_carrier() out of if (!bond_has_slaves(bond))
statement.
Reproducer:
$ insmod bonding.ko mode=0 miimon=100 max_bonds=2
$ ifconfig bond0 up
$ ifenslave bond0 eth0 eth1
$ ifconfig eth0 down
$ ifenslave -d bond0 eth1
$ cat /proc/net/bonding/bond0

IPv6 GRE tunnels are not being offloaded, this is caused by a missing
netdev offload check. The functionality of IPv6 GRE tunnel offloading
was previously added but this check was not included. Adding the
ip6gretap check allows IPv6 GRE tunnels to be offloaded correctly.

At boot on the BCM2711, if the HDMI controllers are running, the CRTC
driver will disable itself and its associated HDMI controller to work
around a hardware bug that would leave some pixels stuck in a FIFO.
In order to avoid that issue, we need to run some operations in lockstep
between the CRTC and HDMI controller, and we need to make sure the HDMI
controller will be powered properly.
However, since we haven't enabled it through KMS, the runtime_pm state
is off at this point so we need to make sure the device is powered
through pm_runtime_resume_and_get, and once the operations are complete,
we call pm_runtime_put.
However, the HDMI controller will do that itself in its
post_crtc_powerdown, which means we'll end up calling pm_runtime_put for
a single pm_runtime_get, throwing the reference counting off. Let's
remove the pm_runtime_put call in the CRTC code in order to have the
proper counting.

With the existing logic where clear_ack is true (HW doesn’t support
auto clear for ICR), interrupt clear register reset is not handled
properly. Due to this only the first interrupts get processed properly
and further interrupts are blocked due to not resetting interrupt
clear register.
Example for issue case where Invert_ack is false and clear_ack is true:
Say Default ISR=0x00 & ICR=0x00 and ISR is triggered with 2
interrupts making ISR = 0x11.
Step 1: Say ISR is set 0x11 (store status_buff = ISR). ISR needs to
be cleared with the help of ICR once the Interrupt is processed.
Step 2: Write ICR = 0x11 (status_buff), this will clear the ISR to 0x00.
Step 3: Issue - In the existing code, ICR is written with ICR =
~(status_buff) i.e ICR = 0xEE -> This will block all the interrupts
from raising except for interrupts 0 and 4. So expectation here is to
reset ICR, which will unblock all the interrupts.
if (chip->clear_ack) {
if (chip->ack_invert && !ret)
........
else if (!ret)
ret = regmap_write(map, reg,
~data->status_buf[i]);
So writing 0 and 0xff (when ack_invert is true) should have no effect, other
than clearing the ACKs just set.

When the gadget driver hasn't been (yet) configured, and the cable is
connected to a HOST, the SFTDISCON gets cleared unconditionally, so the
HOST tries to enumerate it.
At the host side, this can result in a stuck USB port or worse. When
getting lucky, some dmesg can be observed at the host side:
new high-speed USB device number ...
device descriptor read/64, error -110
Fix it in drd, by checking the enabled flag before calling
dwc2_hsotg_core_connect(). It will be called later, once configured,
by the normal flow:
- udc_bind_to_driver
- usb_gadget_connect
- dwc2_hsotg_pullup

Daniel Gibson reports that the n_tty code gets line termination wrong in
very specific cases:
"If you feed a line with exactly 64 chars + terminating newline, and
directly afterwards (without reading) another line into a pseudo
terminal, the the first read() on the other side will return the 64
char line *without* terminating newline, and the next read() will
return the missing terminating newline AND the complete next line (if
it fits in the buffer)"
and bisected the behavior to commit 3b830a9c34d5 ("tty: convert
tty_ldisc_ops 'read()' function to take a kernel pointer").
Now, digging deeper, it turns out that the behavior isn't exactly new:
what changed in commit 3b830a9c34d5 was that the tty line discipline
.read() function is now passed an intermediate kernel buffer rather than
the final user space buffer.
And that intermediate kernel buffer is 64 bytes in size - thus that
special case with exactly 64 bytes plus terminating newline.
The same problem did exist before, but historically the boundary was not
the 64-byte chunk, but the user-supplied buffer size, which is obviously
generally bigger (and potentially bigger than N_TTY_BUF_SIZE, which
would hide the issue entirely).
The reason is that the n_tty canon_copy_from_read_buf() code would look
ahead for the EOL character one byte further than it would actually
copy. It would then decide that it had found the terminator, and unmark
it as an EOL character - which in turn explains why the next read
wouldn't then be terminated by it.
Now, the reason it did all this in the first place is related to some
historical and pretty obscure EOF behavior, see commit ac8f3bf8832a
("n_tty: Fix poll() after buffer-limited eof push read") and commit
40d5e0905a03 ("n_tty: Fix EOF push handling").
And the reason for the EOL confusion is that we treat EOF as a special
EOL condition, with the EOL character being NUL (aka "__DISABLED_CHAR"
in the kernel sources).
So that EOF look-ahead also affects the normal EOL handling.
This patch just removes the look-ahead that causes problems, because EOL
is much more critical than the historical "EOF in the middle of a line
that coincides with the end of the buffer" handling ever was.
Now, it is possible that we should indeed re-introduce the "look at next
character to see if it's a EOF" behavior, but if so, that should be done
not at the kernel buffer chunk boundary in canon_copy_from_read_buf(),
but at a higher level, when we run out of the user buffer.
In particular, the place to do that would be at the top of
'n_tty_read()', where we check if it's a continuation of a previously
started read, and there is no more buffer space left, we could decide to
just eat the __DISABLED_CHAR at that point.
But that would be a separate patch, because I suspect nobody actually
cares, and I'd like to get a report about it before bothering.

Add and ACPI idle power level limit for 32-bit ThinkPad T40.
There is a regression on T40 introduced by commit d6b88ce2, starting
with kernel 5.16:

ACPI: processor idle: Allow playing dead in C3 state
The above patch is trying to enter C3 state during init, what is causing
a T40 system freeze. I have not found a similar issue on any other of my
32-bit machines.
The fix is to add another exception to the processor_power_dmi_table[] list.
As a result the dmesg shows as expected:
[2.155398] ACPI: IBM ThinkPad T40 detected - limiting to C2 max_cstate. Override with "processor.max_cstate=9"
[2.155404] ACPI: processor limited to max C-state 2
The fix is trivial and affects only vintage T40 systems.

With v2 hardware, an IRQ can be configured to trigger on both edges via
a bit in the int_bothedge register. Currently, the driver sets this bit
when changing the trigger type to IRQ_TYPE_EDGE_BOTH, but fails to reset
this bit if the trigger type is later changed to something else. This
causes spurious IRQs, and when using gpio-keys with wakeup-event-action
set to EV_ACT_(DE)ASSERTED, those IRQs translate into spurious wakeups.

Paul reports that the ACPI core complains on every boot about a missing
CEDT table. Unlike the standard NUMA tables (SRAT, MADT, and SLIT) that
are critical to NUMA init, CEDT is only expected on CXL platforms. Given
the notice is not actionable lower its severity to debug.

A broken device may give an extreme offset like 0xFFF0
and a reasonable length for a fragment. In the sanity
check as formulated now, this will create an integer
overflow, defeating the sanity check. Both offset
and offset + len need to be checked in such a manner
that no overflow can occur.
And those quantities should be unsigned.

Do alignment logic properly and use the "ptr" local variable for
calculating the remainder of the alignment.
This became an issue because struct edac_mc_layer has a size that is not
zero modulo eight, and the next offset that was prepared for the private
data was unaligned, causing an alignment exception.
The patch in Fixes: which broke this actually wanted to "what we
actually care about is the alignment of the actual pointer that's about
to be returned." But it didn't check that alignment.
Use the correct variable "ptr" for that.

The -ENODEV return value from xhci_check_args() is incorrectly changed
to -EINVAL in a couple places before propagated further.
xhci_check_args() returns 4 types of value, -ENODEV, -EINVAL, 1 and 0.
xhci_urb_enqueue and xhci_check_streams_endpoint return -EINVAL if
the return value of xhci_check_args <= 0.
This causes problems for example r8152_submit_rx, calling usb_submit_urb
in drivers/net/usb/r8152.c.
r8152_submit_rx will never get -ENODEV after submiting an urb when xHC
is halted because xhci_urb_enqueue returns -EINVAL in the very beginning.

Commit e0082698b689 ("usb: dwc3: ulpi: conditionally resume ULPI PHY")
fixed an issue where ULPI transfers would timeout if any requests where
send to the phy sometime after init, giving it enough time to auto-suspend.
Commit e5f4ca3fce90 ("usb: dwc3: ulpi: Fix USB2.0 HS/FS/LS PHY suspend
regression") changed the behavior to instead of clearing the
DWC3_GUSB2PHYCFG_SUSPHY bit, add an extra sleep when it is set.
But on Bay Trail devices, when phy_set_mode() gets called during init,
this leads to errors like these:
[ 28.451522] tusb1210 dwc3.ulpi: error -110 writing val 0x01 to reg 0x0a
[ 28.464089] tusb1210 dwc3.ulpi: error -110 writing val 0x01 to reg 0x0a
Add "snps,dis_u2_susphy_quirk" to the settings for Bay Trail devices to
fix this. This restores the old behavior for Bay Trail devices, since
previously the DWC3_GUSB2PHYCFG_SUSPHY bit would get cleared on the first
ulpi_read/_write() and then was never set again.
