crypto: arm/aes-ce - build for v8 architecture explicitly
The NEON/Crypto Extensions based AES implementation for 32-bit ARM
can be built in a kernel that targets ARMv6 CPUs and higher, even
though the actual code will not be able to run on that generation,
but it allows for a portable image to be generated that can will
use the special instructions only when they are available.
Since those instructions are part of a FPU profile rather than a
CPU profile, we don't override the architecture in the assembler
code, and most of the scalar code is simple enough to be ARMv6
compatible. However, that changes with commit
c61b1607ed4fbbf2,
which introduces calls to the movw/movt instructions, which are
v7+ only.
So override the architecture in the .S file to armv8-a, which
matches the architecture specification in the crypto-neon-fp-armv8
FPU specificier that we already using. Note that using armv7-a
here may trigger an issue with the upcoming Clang 10 release,
which no longer permits .arch/.fpu combinations it views as
incompatible.

hwrng: core - don't wait on add_early_randomness()
add_early_randomness() is called by hwrng_register() when the
hardware is added. If this hardware and its module are present
at boot, and if there is no data available the boot hangs until
data are available and can't be interrupted.
For instance, in the case of virtio-rng, in some cases the host can be
not able to provide enough entropy for all the guests.
We can have two easy ways to reproduce the problem but they rely on
misconfiguration of the hypervisor or the egd daemon:
- if virtio-rng device is configured to connect to the egd daemon of the
host but when the virtio-rng driver asks for data the daemon is not
connected,
- if virtio-rng device is configured to connect to the egd daemon of the
host but the egd daemon doesn't provide data.
The guest kernel will hang at boot until the virtio-rng driver provides
enough data.
To avoid that, call rng_get_data() in non-blocking mode (wait=0)
from add_early_randomness().

padata: unbind parallel jobs from specific CPUs
Padata binds the parallel part of a job to a single CPU and round-robins
over all CPUs in the system for each successive job. Though the serial
parts rely on per-CPU queues for correct ordering, they're not necessary
for parallel work, and it improves performance to run the job locally on
NUMA machines and let the scheduler pick the CPU within a node on a busy
system.
So, make the parallel workqueue unbound.
Update the parallel workqueue's cpumask when the instance's parallel
cpumask changes.
Now that parallel jobs no longer run on max_active=1 workqueues, two or
more parallel works that hash to the same CPU may run simultaneously,
finish out of order, and so be serialized out of order. Prevent this by
keeping the works sorted on the reorder list by sequence number and
checking that in the reordering logic.
padata_get_next becomes padata_find_next so it can be reused for the end
of padata_reorder, where it's used to avoid uselessly queueing work when
the next job by sequence number isn't finished yet but a later job that
hashed to the same CPU has.
The ENODATA case in padata_find_next no longer makes sense because
parallel jobs aren't bound to specific CPUs. The EINPROGRESS case takes
care of the scenario where a parallel job is potentially running on the
same CPU as padata_find_next, and with only one error code left, just
use NULL instead.

The pure NEON AES implementation predates the bit-slicing one, and is
generally slower, unless the algorithm in question can only execute
sequentially.
So advertising the skciphers that the bit-slicing driver implements as
well serves no real purpose, and we can just disable them. Note that the
bit-slicing driver also has a link time dependency on the pure NEON
driver, for CBC encryption and for XTS tweak calculation, so we still
need both drivers on systems that do not implement the Crypto Extensions.
At the same time, expose those modaliases for the AES instruction based
driver. This is necessary since otherwise, we may end up loading the
wrong driver when any of the skciphers are instantiated before the CPU
capability based module loading has completed.
Finally, add the missing modalias for cts(cbc(aes)) so requests for
this algorithm will autoload the correct module.

}
} else {

}
3. Invert the check for !caam_imx:
if (caam_little_end) {
if (caam_imx) {
iowrite32(data >> 32, (u32 __iomem *)(reg));
iowrite32(data, (u32 __iomem *)(reg) + 1);

}
} else {

4. Make use of iowrite64* helpers from <linux/io-64-nonatomic-hi-lo.h>
if (caam_little_end) {
if (caam_imx) {
