When complex algorithms that depend on other algorithms are built
into the kernel, the order of registration must be done such that
the underlying algorithms are ready before the ones on top are
registered.  As otherwise they would fail during the self-test
which is required during registration.

In the past we have used subsystem initialisation ordering to
guarantee this.  The number of such precedence levels are limited
and they may cause ripple effects in other subsystems.

This patch solves this problem by delaying all self-tests during
boot-up for built-in algorithms.  They will be tested either when
something else in the kernel requests for them, or when we have
finished registering all built-in algorithms, whichever comes
earlier.

After reset or boot, QAT 4xxx devices are inactive and require to be
explicitly activated.
This is done by writing the DRV_ACTIVE bit in the PM_INTERRUPT register
and polling the PM_INIT_STATE to make sure that the transaction has
completed properly.

If this is not done, the driver will fail the initialization sequence
reporting the following message:
    [   22.081193] 4xxx 0000:f7:00.0: enabling device (0140 -> 0142)

    [   22.825099] 4xxx: probe of 0000:f7:00.0 failed with error -14

The patch also temporarily disables the power management source of
interrupt, to avoid possible spurious interrupts as the power management
feature is not fully supported.

The device init function has been added to adf_dev_init(), and not in the
probe of 4xxx to make sure that the device is re-enabled in case of
reset.

Note that the error code reported by hw_data->init_device() in
adf_dev_init() has been shadowed for consistency with the other calls
in the same function.

On newer CAAM versions, not all accelerators are disabled if the SoC is
a non-E variant. While the driver checks most of the modules for
availability, there is one - PKHA - which sticks out. On non-E variants
it is still reported as available, that is the number of instances is
non-zero, but it has limited functionality. In particular it doesn't
support encryption and decryption, but just signing and verifying. This
is indicated by a bit in the PKHA_MISC field. Take this bit into account
if we are checking for availability.

In the code for xts_crypt(), we check for the err value returned by
skcipher_walk_virt() and return from the function if it is non zero.
However, skcipher_walk_virt() can set walk.nbytes to 0, which would cause
us to call kernel_fpu_begin(), and then skip the kernel_fpu_end() call.

This patch checks for the walk.nbytes value instead, and returns if
walk.nbytes is 0. This prevents us from calling kernel_fpu_begin() in
the first place and also covers the case of having a non zero err value
returned from skcipher_walk_virt().

the common case is for the authenticate, en/decrypt and finalize SIMD
helpers to all be called exactly once in sequence. Since
kernel_neon_end() now involves manipulation of the preemption state as
well as the softirq mask state, let's reduce the number of times we are

In SIMD accelerated crypto drivers, we typically yield the SIMD unit
after processing 4 KiB of input, to avoid scheduling blackouts caused by
the fact that claiming the SIMD unit disables preemption as well as
softirq processing.

The arm64 CCM driver does this implicitly for the ciphertext, due to the
fact that the skcipher API never processes more than a single page at a
time. However, the scatterwalk performed by this driver when processing
the authenticate-only data will keep the SIMD unit occupied until it
completes.

So cap the scatterwalk steps to 4 KiB.
