Serdev currently only supports a single slave device, but the required
sanity checks to prevent further registration attempts were missing.
If a serial-port node has two child nodes with compatible properties,
the OF code would try to register two slave devices using the same id
and name. Driver core will not allow this (and there will be loud
complaints), but the controller's slave pointer would already have been
set to address of the soon to be deallocated second struct
serdev_device. As the first slave device remains registered, this can
lead to later use-after-free issues when the slave callbacks are
accessed.
Note that while the serdev registration helpers are exported, they are
typically only called by serdev core. Any other (out-of-tree) callers
must serialise registration and deregistration themselves.

UART devices is expected to be enumerated by SerDev subsystem.
During ACPI scan, serial devices behind SPI, I2C or UART buses are not
enumerated, allowing them to be enumerated by their respective parents.
Rename *spi_i2c_slave* to *serial_bus_slave* as this will be used for serial
devices on serial buses (SPI, I2C or UART).
On Macs an empty ResourceTemplate is returned for uart slaves.
Instead the device properties "baud", "parity", "dataBits", "stopBits" are
provided. Add a check for "baud" in acpi_is_serial_bus_slave().

While the standard UART port can use a single IRQ that 'sums' both RX
and TX interrupts, the extended port cannot and has to use two different
ISR, one for each direction. The standard port also has the hability
to use two separate interrupts (one for each direction).
The logic is then: either there is only one unnamed interrupt on the
standard port and this interrupt must be used for both directions
(this is legacy bindings); or all the interrupts must be described and
named 'uart-sum' (if available), 'uart-rx', 'uart-tx' and two separate
handlers for each direction will be used.

for the TX interrupt to continue the transfer.

When receiving data on RX pin before ->uart_startup() is called, some
error bits in the state register could be set up (like BRK_DET).
This is harmless when using only the standard UART (error bits are
read-only), but may procude an endless loop once in the extended UART
RX interrupt handler (error bits must be cleared).
Clear the status register in ->uart_startup() to avoid this situation.

first one, plus additional features, but it has a different register
layout (some bit fields are also moved inside the registers).
Clearly separate register offsets and bit fields that differ between the
standard and the extended IP. Access them in a generic way. Rename the
defines with the "STD" prefix for future distinction with "EXT" defines.
Point to these defines in the main driver data structure.
The early console only uses the standard port (not extended).

In con_font_set(), when we need to guess font height (for
compat reasons?), the current approach uses multiple userspace
fetches, i.e., get_user(tmp, &charmap[32*i+h-1]), to derive
the height. This has two drawbacks:
1. performance: accessing userspace memory is less efficient than
directly de-reference the byte
2. security: a more critical problem is that the height derived
might not match with the actual font.data. This is because a user
thread might race condition to change the memory of op->data after
the op->height guessing but before the second fetch: font.data =
memdup_user(op->data, size). Leaving font.height = 32 while the
actual height is 1 or vice-versa.
This patch tries to resolve both issues by re-locating the height
guessing part after the font.data is fetched in. In this way, the
userspace data is fetched in one shot and we directly dereference
the font.data in kernel space to probe for the height.

Pull block fixes from Jens Axboe:
"A collection of fixes for this series. This contains:
- NVMe pull request from Christoph, one uuid attribute fix, and one
fix for the controller memory buffer address for remapped BARs.
- use-after-free fix for bsg, from Benjamin Block.
- bcache race/use-after-free fix for a list traversal, fixing a
regression in this merge window. From Coly Li.
- null_blk change configfs dependency change from a 'depends' to a
'select'. This is a change from this merge window as well. From me.
- nbd signal fix from Josef, fixing a regression introduced with the
status code changes.
- nbd MAINTAINERS mailing list entry update.
- blk-throttle stall fix from Joseph Qi.
- blk-mq-debugfs fix from Omar, fixing an issue where we don't
register the IO scheduler debugfs directory, if the driver is
loaded with it. Only shows up if you switch through the sysfs
interface"
* 'for-linus' of git://git.kernel.dk/linux-block:
bsg-lib: fix use-after-free under memory-pressure
nvme-pci: Use PCI bus address for data/queues in CMB

nvme: fix visibility of "uuid" ns attribute
bcache: use llist_for_each_entry_safe() in __closure_wake_up()
- Bring initialisation of user space undefined instruction handling
early (core_initcall) since late_initcall() happens after modprobe in
initramfs is invoked. Similar fix for fpsimd initialisation
- Increase the kernel stack when KASAN is enabled
- Bring the PCI ACS enabling earlier via the
iort_init_platform_devices()
- Fix misleading data abort address printing (decimal vs hex)

Pull btrfs fixes from David Sterba:
"Two more fixes for bugs introduced in 4.13.
The sector_t problem with 32bit architecture and !LBDAF config seems
serious but the number of affected deployments is hopefully low.
The clashing status bits could lead to a confusing in-memory state of
the whole-filesystem operations if used with the quota override sysfs
knob"
* 'for-4.14-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
Btrfs: fix overlap of fs_info::flags values
btrfs: avoid overflow when sector_t is 32 bit
