Extend all cable info APIs with 'slot_index' argument.
For main board, slot will always be set to zero and these APIs will work
as before. If reading cable information is required from cages located
on line cards, slot should be set to the physical slot number, where
line card is located in modular systems.

A recent patch[1] from Eric Dumazet flipped the order in which the
keepalive timer and the keepalive worker were cancelled in order to fix a
syzbot reported issue[2]. Unfortunately, this enables the mirror image bug
whereby the timer races with rxrpc_exit_net(), restarting the worker after
it has been cancelled:
CPU 1 CPU 2
=============== =====================
if (rxnet->live)
<INTERRUPT>
rxnet->live = false;
cancel_work_sync(&rxnet->peer_keepalive_work);
rxrpc_queue_work(&rxnet->peer_keepalive_work);
del_timer_sync(&rxnet->peer_keepalive_timer);
Fix this by restoring the removed del_timer_sync() so that we try to remove
the timer twice. If the timer runs again, it should see ->live == false
and not restart the worker.

Commit 932d596378b0 ("serial: 8250: Return early in .start_tx() if there

runtime PM stopped idling. This is because serial8250_rpm_put_tx() is now

Commit 76821e222c18 ("serial: imx: ensure that RX irqs are off if RX is
off") accidentally enabled overrun interrupts unconditionally when
deferring DMA enable until after the receiver has been enabled during
startup.
Fix this by using the DMA-initialised instead of DMA-enabled flag to
determine whether overrun interrupts should be enabled.
Note that overrun interrupts are already accounted for in
imx_uart_clear_rx_errors() when using DMA since commit 41d98b5da92f
("serial: imx-serial - update RX error counters when DMA is used").

The current timeout for draining the tx fifo in RS485 mode is calculated by
multiplying the time it takes to transmit one character (with the given
baud rate) with the maximal number of characters in the tx queue.
This timeout is too short for two reasons:
First when calculating the time to transmit one character integer division
is used which may round down the result in case of a remainder of the
division.
Fix this by rounding up the division result.
Second the hardware may need additional time (e.g for first putting the
characters from the fifo into the shift register) before the characters are
actually put onto the wire.
To be on the safe side double the current maximum number of iterations
that are used to wait for the queue draining.

Now fsl_lpuart driver use both of_alias_get_id() and ida_simple_get() in
.probe(), which has the potential bug. For example, when remove the
lpuart7 alias in dts, of_alias_get_id() will return error, then call
ida_simple_get() to allocate the id 0 for lpuart7, this may confilct
with the lpuart4 which has alias 0.
aliases {
...
serial0 = &lpuart4;
serial1 = &lpuart5;
serial2 = &lpuart6;
serial3 = &lpuart7;
}
So remove the ida_simple_get() in .probe(), return an error directly
when calling of_alias_get_id() fails, which is consistent with other
uart drivers behavior.

When flow control is enabled, the UART should set RTS to false
during suspend to stop incoming data. Currently, the suspend
routine sets the mctrl register in the uart to zero, but leaves
the shadow version in the uart_port struct alone so that resume
can restore it. This causes a problem later in suspend when
serial8250_do_shutdown() is called which uses the shadow mctrl
register to clear some additional bits but ends up restoring RTS.
The solution is to clear RTS from the shadow version before
serial8250_do_shutdown() is called and restore it after.

Introduce the UART_CAP_NOTEMT capability. The capability indicates that
the UART doesn't have an interrupt available on TEMT.
In the case where the device does not support it, we calculate the
maximum time it could take for the transmitter to empty the
shift register. When we get in the situation where we get the
THRE interrupt, we check if the TEMT bit is set. If it's not, we start
the a timer and recall __stop_tx() after the delay.
The transmit sequence is a bit modified when the capability is set. The
new timer is used between the last interrupt(THRE) and a potential
stop_tx timer.

Several drivers that support setting the RS485 configuration via userspace
implement one or more of the following tasks:
- in case of an invalid RTS configuration (both RTS after send and RTS on
send set or both unset) fall back to enable RTS on send and disable RTS
after send
- nullify the padding field of the returned serial_rs485 struct
- copy the configuration into the uart port struct
- limit RTS delays to 100 ms
Move these tasks into the serial core to make them generic and to provide
a consistent behaviour among all drivers.

Provide information in the kernel log as to what configuration option to
enable for PCI UART devices that have been blacklisted in the generic
PCI 8250 UART driver and which have a dedicated driver available to
handle that has been disabled. The rationale is there is no easy way
for the user to map a specific PCI vendor:device pair to an individual
dedicated driver while the generic driver has this information readily
available and it will likely be confusing that the generic driver does
not register such a port.
This is unlike usual drivers, such as drivers/net/ethernet/3com/3c59x.c
which handles all the hardware family members regardless of differences
between them, and following an existing example where a serio driver
provides suggestions as to the correct configuration options to use:
psmouse serio1: synaptics: The touchpad can support a better bus than the too old PS/2 protocol. Make sure MOUSE_PS2_SYNAPTICS_SMBUS and RMI4_SMB are enabled to get a better touchpad experience.
A message is then printed like:
serial 0000:04:00.3: ignoring port, enable SERIAL_8250_PERICOM to handle
when an affected device is encountered and the generic driver rejects it.

TTYs in ICANON mode have a special case that allows "pushing" a line
without a regular EOL character (like newline), by using EOF (the EOT
character - ASCII 0x4) as a pseudo-EOL. It is silently discarded, so
the reader of the PTS will receive the line *without* EOF or any other
terminating character.
This special case has an edge case: What happens if the readers buffer
is the same size as the line (without EOF)? Will they be able to tell
if the whole line is received, i.e. if the next read() will return more
of the same line or the next line?
There are two possibilities, that both have (dis)advantages:
1. The next read() returns 0. FreeBSD (13.0) and OSX (10.11) do this.
Advantage: The reader can interpret this as "the line is over".
Disadvantage: read() returning 0 means EOF, the reader could also
interpret it as "there's no more data" and stop reading or even
close the PT.
2. The next read() returns the next line, the EOF is silently discarded.
Solaris (or at least OpenIndiana 2021.10) does this, Linux has done
do this since commit 40d5e0905a03 ("n_tty: Fix EOF push handling");
this behavior was recently broken by commit 359303076163 ("tty:
n_tty: do not look ahead for EOL character past the end of the buffer").
Advantage: read() won't return 0 (EOF), reader less likely to be
confused (and things like `while(read(..)>0)` don't break)
Disadvantage: The reader can't really know if the read() continues
the last line (that filled the whole read buffer) or starts a
new line.
As both options are defensible (and are used by other Unix-likes), it's
best to stick to the "old" behavior since "n_tty: Fix EOF push handling"
of 2013, i.e. silently discard that EOF.
This patch - that I actually got from Linus for testing and only
modified slightly - restores that behavior by skipping an EOF
character if it's the next character after reading is done.
Based on a patch from Linus Torvalds.

Commit d2825fa9365d ("crypto: sm3,sm4 - move into crypto directory")
moved the sm4 library implementation from the lib/crypto directory to
the crypto directory and configured the name as CRYPTO_SM4. The arm64
SM4 NEON/CE implementation depends on this and needs to be modified
uniformly.
Fixes: 4f1aef9b806f ("crypto: arm64/sm4 - add ARMv8 NEON implementation")
Fixes: 5b33e0ec881c ("crypto: arm64/sm4 - add ARMv8 Crypto Extensions implementation")
