A SERIAL_8250_16550A_VARIANTS configuration option has been recently
defined that lets one request the 8250 driver not to probe for 16550A
device features so as to reduce the driver's device startup time in
virtual machines.
Some actual hardware devices require these features to have been fully
determined however for their driver to work correctly, so define a flag
to let drivers request full 16550A feature probing on a device-by-device
basis if required regardless of the SERIAL_8250_16550A_VARIANTS option
setting chosen.
Fixes: dc56ecb81a ("serial: 8250: Support disabling mdelay-filled probes of 16550A variants")

mpc52xx_uart_int_rx_chars() returns unsigned int.
mpc52xx_uart_int_tx_chars() returns int.
The both results are binary ORed to the "keepgoing" variable. Unify all
three to bool as the only interesting value is whether we should keep
looping (true/false).

Both altera_uart_{r,t}x_chars() need only uart_port, not altera_uart. So
pass the former from altera_uart_interrupt() directly.
Apart it maybe saves a dereference, this makes the transition of

The serial-omap driver requires an rts-gpio for RS-485 to work.
Historically it has allowed enabling RS-485 even if no rts-gpio was
specified in the device tree.
That doesn't make any sense, so disable RS-485 on probe if rts-gpio is
missing and disallow user space from enabling it.
Three NULL pointer checks for up->rts_gpiod can be dropped as a result,
simplifying the driver slightly.

All non-UAPI asm/termios.h consist of include of UAPI counterpart
and, possibly, include of linux/uaccess.h
The latter can't be simply removed, even though nothing in
linux/termios.h doesn't depend upon it anymore - there are several
places that rely upon that indirect chain of includes to pull
linux/uaccess.h. So the include needs to be lifted out of there -
we lift into tty_driver.h, serdev.h and places that pull asm/termios.h,
but none of
* linux/uaccess.h (obvious)
* net/sock.h (pulls uaccess.h)
* linux/{tty,tty_driver,serdev}.h (tty.h pulls tty_driver.h)
That leaves us just with the include of UAPI asm/termios.h, which is
what <asm/termios.h> will resolve to if we simply remove non-UAPI header.

On old systems it used to be ^O. Linux had never actually used
the value, but INIT_C_CC (on i386) did initialize it to ^O;
unfortunately, it had a typo in the comment claiming that to be
^U. Most of the architectures copied the (correct) definition
along with mistaken comment. alpha, powerpc and sparc tried
to make the definition match comment.
However, util-linux still resets it to ^O on any architecture,
^O is the historical value, kernel ignores it anyway and finally,

-Wformat was recently re-enabled for builds with clang, then quickly
re-disabled, due to concerns stemming from the frequency of default
argument promotion related warning instances.
commit 258fafcd06 ("Makefile.extrawarn: re-enable -Wformat for clang")
commit 21f9c8a13b ("Revert "Makefile.extrawarn: re-enable -Wformat for clang"")
ISO WG14 has ratified N2562 to address default argument promotion
explicitly for printf, as part of the upcoming ISO C2X standard.
The behavior of clang was changed in clang-16 to not warn for the cited
cases in all language modes.
Add a version check, so that users of clang-16 now get the full effect
of -Wformat. For older clang versions, re-enable flags under the
-Wformat group that way users still get some useful checks related to
format strings, without noisy default argument promotion warnings. I
intentionally omitted -Wformat-y2k and -Wformat-security from being
re-enabled, which are also part of -Wformat in clang-16.

- kerneldoc build warning fixes
- other tiny serial core fixes
All of these have been in linux-next for a while with no reported
problems"
* tag 'tty-6.0-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty:
tty: n_gsm: avoid call of sleeping functions from atomic context
tty: n_gsm: replace kicktimer with delayed_work
tty: n_gsm: initialize more members at gsm_alloc_mux()
tty: n_gsm: add sanity check for gsm->receive in gsm_receive_buf()
tty: serial: atmel: Preserve previous USART mode if RS485 disabled
tty: serial: lpuart: disable flow control while waiting for the transmit engine to complete
tty: Fix lookahead_buf crash with serdev

Here are 3 small staging driver fixes for 6.0-rc4 that resolve some
reported problems and add some a device id:
- new device id for r8188eu driver
- use-after-free bugfixes for the rtl8712 driver
- fix up firmware dependency problem for the r8188eu driver
All of these have been in linux-next for a while with no reported
problems.

staging: rtl8712: fix use after free bugs
staging: r8188eu: Add Rosewill USB-N150 Nano to device tables
staging: r8188eu: add firmware dependency
to the core framework. We had to revert out a commit that affected boot
on some devices that have the CLK_OPS_PARENT_ENABLE flag set. It isn't
critical to have that fix so we'll try again next time.
Driver side fixes include:
- Plug an of node refcount bug in the TI clk driver
- Fix the error handling in the raspberry pi firmware get_rate
so that errors don't look like valid frequencies
- Avoid going out of bounds in the raspberry pi driver too if the
video firmware returns something we're not expecting

We had to revert out a commit that affected boot on some devices that

Driver side fixes include:

The mmap lock protects the page walker from changes to the page tables
during the walk. However a read lock is insufficient to protect those
areas which don't have a VMA as munmap() detaches the VMAs before
downgrading to a read lock and actually tearing down PTEs/page tables.
For users of walk_page_range() the solution is to simply call pte_hole()
immediately without checking the actual page tables when a VMA is not
present. We now never call __walk_page_range() without a valid vma.
For walk_page_range_novma() the locking requirements are tightened to
require the mmap write lock to be taken, and then walking the pgd
directly with 'no_vma' set.
This in turn means that all page walkers either have a valid vma, or
it's that special 'novma' case for page table debugging. As a result,
all the odd '(!walk->vma && !walk->no_vma)' tests can be removed.
