Unbinding the bcm2835aux UART driver raises the following error if the
maximum number of 8250 UARTs is set to 1 (via the 8250.nr_uarts module
parameter or CONFIG_SERIAL_8250_RUNTIME_UARTS):
(NULL device *): Removing wrong port: a6f80333 != fa20408b
That's because bcm2835aux_serial_probe() retrieves UART line number 1
from the devicetree and stores it in data->uart.port.line, while
serial8250_register_8250_port() instead uses UART line number 0,
which is stored in data->line.
On driver unbind, bcm2835aux_serial_remove() uses data->uart.port.line,
which contains the wrong number. Fix it.
The issue does not occur if the maximum number of 8250 UARTs is >= 2.

Following the device's documentation guidance, reading a packet from the
device or writing a packet to it must be atomic. Previously, only
reading device's vacancy (before writing on it) or occupancy (before
reading from it) was locked. Hence, effectively reading the packet or
writing the packet wasn't locked at all. However, reading a packet (and
writing one, to a lesser extent) requires to read 3 different registers
in a specific order, without missing one or else we should reset the
device.
This patch fixes the device's locking mechanism on the FIFO character
device. As the device was using copy_from_user() and copy_to_user(), we
need to replace spinlocks with mutexes.

If the length of the socket buffer is 0xFFFFFFFF (max size for an
unsigned int), then payload_len becomes 0xFFFFFFF1 after subtracting 14
(ETH_HLEN). Then, mdp_len is set to payload_len + 16 (MDP_HDR_LEN)
which overflows and results in a value of 2. These values for
payload_len and mdp_len will pass current buffer size checks.
This patch checks if derived from skb->len sum may overflow.
The check is based on the following idea:
For any `unsigned V1, V2` and derived `unsigned SUM = V1 + V2`,
`V1 + V2` overflows iif `SUM < V1`.

When the ARM accelerated ChaCha driver is built as part of a configuration
that has kernel mode NEON disabled, we expect the compiler to propagate
the build time constant expression IS_ENABLED(CONFIG_KERNEL_MODE_NEON) in
a way that eliminates all the cross-object references to the actual NEON
routines, which allows the chacha-neon-core.o object to be omitted from
the build entirely.
Unfortunately, this fails to work as expected in some cases, and we may
end up with a build error such as
chacha-glue.c:(.text+0xc0): undefined reference to `chacha_4block_xor_neon'
caused by the fact that chacha_doneon() has not been eliminated from the
object code, even though it will never be called in practice.
Let's fix this by adding some IS_ENABLED(CONFIG_KERNEL_MODE_NEON) tests
that are not strictly needed from a logical point of view, but should
help the compiler infer that the NEON code paths are unreachable in
those cases.

When this was originally ported, the 12-byte nonce vectors were left out
to keep things simple. I agree that we don't need nor want a library
interface for 12-byte nonces. But these test vectors were specially
crafted to look at issues in the underlying primitives and related
interactions. Therefore, we actually want to keep around all of the
test vectors, and simply have a helper function to test them with.
Secondly, the sglist-based chunking code in the library interface is
rather complicated, so this adds a developer-only test for ensuring that
all the book keeping is correct, across a wide array of possibilities.
