In previous capability register implementation, qm irq related values
were read from capability registers dynamically when needed. But in
abnormal scenario, e.g. the core is timeout and the device needs to
soft reset and reset failed after disabling the MSE, the device can
not be removed normally, causing the following call trace:

The reason for this call trace is that when the MSE is disabled, the value
of capability registers in the BAR space become invalid. This will make the
subsequent unregister process get the wrong irq vector through capability
registers and get the wrong irq number by pci_irq_vector().

So add a capability table structure to pre-store the valid value of the irq
information capability register in qm init process, avoid obtaining invalid
capability register value after the MSE is disabled.

There are limited number CPT LFs (example 64 LFs on cn10k) and
these LFs are allocated/attached to CPT VF on its creation.
cptpf sysfs parameter "kvf_limits" defines number of CPT LFs
per CPT VF. Default "kvf_limits" is initialized to zero and if
kvf_limits is zero then number of LF allocated are equal to
online cpus in system.

For example on 24 core system, 24 CPT LFs will be attached per VF.
That means no CPT LF available when creating more than 2 CPT VFs
on system which have total 64 LFs. Although VFs gets created but
no LF attached to it.

There seems no reason to default allocate as many LFs as many
online cpus in system. This patch initializes "kvf_limits" to
one to limit one LF allocated per CPT VF. "kvf_limits" can

The input argument `sla_in` is a pointer to a structure that contains
the parameters of the SLA which is being added or updated.
If this pointer is NULL, the function should return an error as
the data required for the algorithm is not available.
By mistake, the logic jumps to the error path which dereferences
the pointer.

This results in a warnings reported by the static analyzer Smatch when
executed without a database:

    drivers/crypto/intel/qat/qat_common/adf_rl.c:871 add_update_sla()
    error: we previously assumed 'sla_in' could be null (see line 812)

This issue was not found in internal testing as the pointer cannot be
NULL. The function add_update_sla() is only called (indirectly) by
the rate limiting sysfs interface implementation in adf_sysfs_rl.c
which ensures that the data structure is allocated and valid. This is
also proven by the fact that Smatch executed with a database does not
report such error.

Fix it by returning with error if the pointer `sla_in` is NULL.

The x86 SHA-256 module contains four implementations: SSSE3, AVX, AVX2,
and SHA-NI.  Commit 1c43c0f1 ("crypto: x86/sha - load modules based
on CPU features") made the module be autoloaded when SSSE3, AVX, or AVX2
is detected.  The omission of SHA-NI appears to be an oversight, perhaps
because of the outdated file-level comment.  This patch fixes this,
though in practice this makes no difference because SSSE3 is a subset of
the other three features anyway.  Indeed, sha256_ni_transform() executes
SSSE3 instructions such as pshufb.

The x86 SHA-1 module contains four implementations: SSSE3, AVX, AVX2,
and SHA-NI.  Commit 1c43c0f1 ("crypto: x86/sha - load modules based

is detected.  The omission of SHA-NI appears to be an oversight, perhaps
because of the outdated file-level comment.  This patch fixes this,
though in practice this makes no difference because SSSE3 is a subset of
the other three features anyway.  Indeed, sha1_ni_transform() executes
SSSE3 instructions such as pshufb.
