* Account for big-endian 2^26 conversion in Poly1305.
* Account for big-endian NEON in Curve25519.
* Fix macros in big-endian AArch64 code so that this will actually run there
at all.
* Prefer if (IS_ENABLED(...)) over ifdef mazes when possible.
* Call simd_relax() within any preempt-disabling glue code every once in a
while so as not to increase latency if folks pass in super long buffers.
* Prefer compiler-defined architecture macros in assembly code, which puts us
in closer alignment with upstream CRYPTOGAMS code, and is cleaner.
* Non-static symbols are prefixed with wg_ to avoid polluting the global
namespace.
* Return a bool from simd_relax() indicating whether or not we were
rescheduled.
* Reflect the proper simd conditions on arm.
* Do not reorder lines in Kbuild files for the simd asm-generic addition,
since we don't want to cause merge conflicts.
* WARN() if the selftests fail in Zinc, since if this is an initcall, it won't
block module loading, so we want to be loud.
* Document some interdependencies beside include statements.
* Add missing static statement to fpu init functions.
* Use union in chacha to access state words as a flat matrix, instead of
casting a struct to a u8 and hoping all goes well. Then, by passing around
that array as a struct for as long as possible, we can update counter[0]
instead of state[12] in the generic blocks, which makes it clearer what's
happening.
* Remove __aligned(32) for chacha20_ctx since we no longer use vmovdqa on x86,
and the other implementations do not require that kind of alignment either.
* Submit patch to ARM tree for adjusting RiscPC's cflags to be -march=armv3 so
that we can build code that uses umull.
* Allow CONFIG_ARM[64] to imply [!]CONFIG_64BIT, and use zinc arch config
variables consistently throughout.
* Document rationale for the 2^26->2^64/32 conversion in code comments.
* Convert all of remaining BUG_ON to WARN_ON.
* Replace `bxeq lr` with `reteq lr` in ARM assembler to be compatible with old
ISAs via the macro in <asm/assembler.h>.
* Do not allow WireGuard to be a built-in if IPv6 is a module.
* Writeback the base register and reorder multiplications in the NEON x25519
implementation.
* Try all combinations of different implementations in selftests, so that
potential bugs are more immediately unearthed.
* Self tests and SIMD glue code work with #include, which lets the compiler
optimize these. Previously these files were .h, because they were included,
but a simple grep of the kernel tree shows 259 other files that carry out
this same pattern. Only they prefer to instead name the files with a .c
instead of a .h, so we now follow the convention.
* Support many more platforms in QEMU, especially big endian ones.
* Kernels < 3.17 don't have read_cpuid_part, so fix building there.

The IRQ init structs are marked as __initconst which
means this memory can be free after init.
On this platform, the PCI IRQ init happens very late _after_ the
kernel already freed the memory allocated for these structs.
During IRQ allocation, the allocation function is passed
with invalid data at this point leading to following error:
[ 0.000000] SoC: Qualcomm Atheros QCA9533 ver 2 rev 0
[ 2.382828] Freeing unused kernel memory: 264K
[ 34.414816] pci 0000:00:00.0: no irq found for pin 1
and
[ 0.000000] SoC: Qualcomm Atheros QCA956X ver 1 rev 0
[ 2.125401] Freeing unused kernel memory: 284K
[ 9.526479] pci 0000:00:00.0: no irq found for pin 1
After this patch:
[ 14.960814] pci 0000:00:00.0: using irq 40 for pin 1
Commit 318e19ba67 ("ar71xx: add v4.14 support") fixed this for the
default targets already present in the source by default but forgot
to remove the __initconst attribute for targets QCA953x and QCA956x
which are only added later through platform patches.

Config option to limit maximum compression streams per zram dev for
multicore CPU's. This could be defined via 'zram_comp_streams' option in
the 'system' section of '/etc/config/system' file or via cli (for e.x.
with 'uci set system.@System[0].zram_comp_streams=2 && uci commit
system'). Default is number of logical CPU cores.

Use only one zram swap device of the specified $size instead of
[N x $size] devices for multicore CPUs Now zram module uses multiple
compression streams for each dev by default, so we do not need to create
several zram devs to utilize multicore CPUs.

Patch 303 is required for Traverse LS1043 targets when using the NXP DPAA1 driver.
The recent refresh of 4.9 patches on layerscape changed how FMan/BMan memory regions
were defined and meant Ethernet stopped working on these boards.
(Note that these definitions are only required for NXP's Ethernet driver, the new
upstream driver in >=4.15 works using the DTS provided in files/)

On the Netgear WNDAP620, the emac ethernet isn't receiving nor
xmitting any frames from/to the RTL8363SB (identifies itself
as a RTL8367RB).
This is caused by hardware not knowing the right forced link
settings (speed, duplex, pause, etc.) settings.

The swconfig switch led driver has the ability to switch
between a "link, rx and/or tx" mode. However, this feature
was not implemented in uci, the led init script and
config_generate.
This patch adds a seventh parameter to the
ucidef_set_led_switch() function. The accepted values for
this parameter are: link, rx and tx.
Any permutations of these three values are supported, as
long as they are properly encased with quotes.
If the parameter is not specified it will default to "all"
(link rx tx).
