Enable the detection of hangs by setting watchdog timers (WDTs) on
generations that supports that feature.
The default timeout value comes from HW specs. WTDs are reset each time
an accelerator wins arbitration and is able to send/read a command to/from
an accelerator.
The value has added significant margin to make sure there are no spurious
timeouts. The scope of watchdog is per QAT device.
If a timeout is detected, the firmware resets the accelerator and
returns a response descriptor with an appropriate error code.

In adf_create_ring, if the callee adf_init_ring() failed, the callee will
free the ring->base_addr by dma_free_coherent() and return -EFAULT. Then
adf_create_ring will goto err and the ring->base_addr will be freed again
in adf_cleanup_ring().
My patch sets ring->base_addr to NULL after the first freed to avoid the
double free.

ADF_STATUS_PF_RUNNING is (only) used and checked by adf_vf2pf_shutdown()
before calling adf_iov_putmsg()->mutex_lock(vf2pf_lock), however the
vf2pf_lock is initialized in adf_dev_init(), which can fail and when it
fail, the vf2pf_lock is either not initialized or destroyed, a subsequent
use of vf2pf_lock will cause issue.
To fix this issue, only set this flag if adf_dev_init() returns 0.

The hardware specific function adf_get_arbiter_mapping() modifies
the static array thrd_to_arb_map to disable mappings for AEs
that are disabled. This static array is used for each device
of the same type. If the ae mask is not identical for all devices
of the same type then the arbiter mapping returned by
adf_get_arbiter_mapping() may be wrong.
This patch fixes this problem by ensuring the static arbiter
mapping is unchanged and the device arbiter mapping is re-calculated
each time based on the static mapping.

Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2,
and <crypto/sha3.h> contains declarations for SHA-3.
This organization is inconsistent, but more importantly SHA-1 is no
longer considered to be cryptographically secure. So to the extent
possible, SHA-1 shouldn't be grouped together with any of the other SHA
versions, and usage of it should be phased out.
Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and
<crypto/sha2.h>, and make everyone explicitly specify whether they want
the declarations for SHA-1, SHA-2, or both.
This avoids making the SHA-1 declarations visible to files that don't
want anything to do with SHA-1. It also prepares for potentially moving
sha1.h into a new insecure/ or dangerous/ directory.
