DW APB SSI controller can be used by the two SPI core interfaces:
traditional SPI transfers and SPI memory operations. The controller needs
to be accordingly configured at runtime when the corresponding operations
are executed. In order to do that for the both interfaces from a single
function we introduce a new data wrapper for the transfer mode, data
width, number of data frames (for the automatic data transfer) and the bus
frequency. It will be used by the update_config() method to tune the DW
APB SSI up.
The update_config() method is made exported to be used not only by the DW
SPI core driver, but by the glue layer drivers too. This will be required
in a coming further commit.

Rx sample delay can be SPI device specific, and should be synchronously
initialized with the rest of the communication and peripheral device
related controller setups. So let's move the Rx-sample delay setup into
the DW APB SSI configuration update method.

The code currently responsible for the SPI communication speed setting up
is a bit messy. Most likely for some historical reason the bus frequency
is saved in the peripheral chip private data. It's pointless now since the
custom communication speed is a SPI-transfer-specific thing and only if
there is no SPI transfer data specified (like during the SPI memory
operations) it can be taken from the SPI device structure. But even in the
later case there is no point in having the clock divider and the SPI bus
frequency saved in the chip data, because the controller can be used for
both SPI-transfer-based and SPI-transfer-less communications. From
software point of view keeping the current clock divider in an SPI-device
specific storage may give a small performance gain (to avoid sometimes a
round-up division), but in comparison to the total SPI transfer time it
just doesn't worth saving a few CPU cycles in comparison to the total SPI
transfer time while having the harder to read code. The only optimization,
which could worth preserving in the code is to avoid unnecessary DW SPI
controller registers update if it's possible. So to speak let's simplify
the SPI communication speed update procedure by removing the clock-related
fields from the peripheral chip data and update the DW SPI clock divider
only if it's really changed. The later change is reached by keeping the
effective SPI bus speed in the internal DW SPI private data.

The SPI bus speed update functionality will be useful in another parts of
the driver too (like to implement the SPI memory operations and from the
DW SPI glue layers). Let's move it to the update_cr0() method then and
since the later is now updating not only the CTRLR0 register alter its
prototype to have a generic function name not related to CR0.
Leave the too long line with the chip->clk_div setting as is for now,
since it's going to be changed later anyway.

Indeed there is no point in detecting the SPI peripheral device parameters
and initializing the CR0 register fields each time an SPI transfer is
executed. Instead let's define a dedicated CR0 chip-data member, which
will be initialized in accordance with the SPI device settings at the
moment of setting it up.
By doing so we'll finally make the SPI device chip_data serving as it's
supposed to - to preserve the SPI device specific DW SPI configuration.
See spi-fsl-dspi.c, spi-pl022.c, spi-pxa2xx.c drivers for example of the
way the chip data is utilized.

Currently DWC SSI core is supported by means of setting up the
core-specific update_cr0() callback. It isn't suitable for multiple
reasons. First of all having exported several methods doing the same thing
but for different chips makes the code harder to maintain. Secondly the
spi-dw-core driver exports the methods, then the spi-dw-mmio driver sets
the private data callback with one of them so to be called by the core
driver again. That makes the code logic too complicated. Thirdly using
callbacks for just updating the CR0 register is problematic, since in case
if the register needed to be updated from different parts of the code,
we'd have to create another callback (for instance the SPI device-specific
parameters don't need to be calculated each time the SPI transfer is
submitted, so it's better to pre-calculate the CR0 data at the SPI-device
setup stage).
So keeping all the above in mind let's discard the update_cr0() callbacks,
define a generic and static dw_spi_update_cr0() method and create the
DW_SPI_CAP_DWC_SSI capability, which when enabled would activate the
alternative CR0 register layout.
While at it add the comments to the code path of the normal DW APB SSI
controller setup to make the dw_spi_update_cr0() method looking coherent.

Use kstrndup() to copy line labels from the userspace provided char
array, rather than ensuring the char array contains a null terminator
and using kstrdup().
Note that the length provided to kstrndup() still assumes that the char
array does contain a null terminator, so the maximum string length is one
less than the array. This is consistent with the previous behaviour.

Currently, init_listener() tries to prevent adding a filter with
SECCOMP_FILTER_FLAG_NEW_LISTENER if one of the existing filters already
has a listener. However, this check happens without holding any lock that
would prevent another thread from concurrently installing a new filter
(potentially with a listener) on top of the ones we already have.
Theoretically, this is also a data race: The plain load from
current->seccomp.filter can race with concurrent writes to the same
location.
Fix it by moving the check into the region that holds the siglock to guard
against concurrent TSYNC.
(The "Fixes" tag points to the commit that introduced the theoretical
data race; concurrent installation of another filter with TSYNC only
became possible later, in commit 51891498f2da ("seccomp: allow TSYNC and
USER_NOTIF together").)

In order to make adding configurable features into seccomp easier,
it's better to have the options at one single location, considering
especially that the bulk of seccomp code is arch-independent. An quick
look also show that many SECCOMP descriptions are outdated; they talk
about /proc rather than prctl.
As a result of moving the config option and keeping it default on,
architectures arm, arm64, csky, riscv, sh, and xtensa did not have SECCOMP
on by default prior to this and SECCOMP will be default in this change.
Architectures microblaze, mips, powerpc, s390, sh, and sparc have an
outdated depend on PROC_FS and this dependency is removed in this change.

portions of the syscall number and return values need to be set at which
different phases. For non-powerpc, all changes are made during ptrace
syscall entry, as before. For powerpc, the syscall number is changed at
ptrace syscall entry and the syscall return value is changed on ptrace
syscall exit.

Some firmware files trigger a PHY soft reset and don't wait for it to
be finished. PHY register writes directly after applying the firmware
may fail or provide unexpected results therefore. Fix this by waiting
for bit BMCR_RESET to be cleared after applying firmware.
There's nothing wrong with the referenced change, it's just that the
fix will apply cleanly only after this change.

With multiple DNAT rules it's possible that after destination
translation the resulting tuples collide.
For example, two openvswitch flows:
nw_dst=10.0.0.10,tp_dst=10, actions=ct(commit,table=2,nat(dst=20.0.0.1:20))
nw_dst=10.0.0.20,tp_dst=10, actions=ct(commit,table=2,nat(dst=20.0.0.1:20))
Assuming two TCP clients initiating the following connections:
10.0.0.10:5000->10.0.0.10:10
10.0.0.10:5000->10.0.0.20:10
Both tuples would translate to 10.0.0.10:5000->20.0.0.1:20 causing
nf_conntrack_confirm() to fail because of tuple collision.
Netfilter handles this case by allocating a null binding for SNAT at
egress by default. Perform the same operation in openvswitch for DNAT
if no explicit SNAT is requested by the user and allocate a null binding
for SNAT for packets in the "original" direction.
