The mv_cesa_dma_add_op() function builds a mv_cesa_tdma_desc structure
to copy the operation description to the SRAM, but doesn't explicitly
initialize the destination of the copy. It works fine because the
operatin description must be copied at the beginning of the SRAM, and
the mv_cesa_tdma_desc structure is initialized to zero when
allocated. However, it is somewhat confusing to not have a destination
defined.

While debugging setkey issues, the following warnings were found while
trying to reinsert the caam module.  Fix this by avoiding the duplicated

Threaded interrupts can perform the function of the tasklet, and much
more safely too - without races when trying to take the tasklet and
interrupt down on device removal.

With the old code, there is a window where we call tasklet_kill().  If
the interrupt handler happens to be running on a different CPU, and
subsequently calls tasklet_schedule(), the tasklet will be re-scheduled
for execution.

Switching to a hardirq/threadirq combination implementation avoids this,
and it also means generic code deals with the teardown sequencing of the
threaded and non-threaded parts.

Strictly, dma_map_sg() may coalesce SG entries, but in practise on iMX

we completely fail to check its return value.  So, fix this properly.

caamhash contains this weird code:

	src_nents = sg_count(req->src, req->nbytes);
	dma_map_sg(jrdev, req->src, src_nents ? : 1, DMA_TO_DEVICE);
	...
	edesc->src_nents = src_nents;

sg_count() returns zero when sg_nents_for_len() returns zero or one.
This means we don't need to use a hardware scatterlist.  However,
setting src_nents to zero causes problems when we unmap:

	if (edesc->src_nents)
		dma_unmap_sg_chained(dev, req->src, edesc->src_nents,
				     DMA_TO_DEVICE, edesc->chained);

as zero here means that we have no entries to unmap.  This causes us
to leak DMA mappings, where we map one scatterlist entry and then
fail to unmap it.

This can be fixed in two ways: either by writing the number of entries
that were requested of dma_map_sg(), or by reworking the "no SG
required" case.

We adopt the re-work solution here - we replace sg_count() with
sg_nents_for_len(), so src_nents now contains the real number of
scatterlist entries, and we then change the test for using the
hardware scatterlist to src_nents > 1 rather than just non-zero.

This change passes my sshd, openssl tests hashing /bin and tcrypt
tests.

The optimised crc32c implementation depends on VMX (aka. Altivec)
instructions, so the kernel must be built with Altivec support in order
for the crc32c code to build.

To be able to generate shared descriptors for AEAD, the authentication size
needs to be known. However, there is no imposed order of calling .setkey,
.setauthsize callbacks.

Thus, in case authentication size is not known at .setkey time, defer it
until .setauthsize is called.

The authsize != 0 check was incorrectly removed when converting the driver
to the new AEAD interface.

There are a few things missed by the conversion to the
new AEAD interface:

1 - echainiv(authenc) encrypt shared descriptor

The shared descriptor is incorrect: due to the order of operations,
at some point in time MATH3 register is being overwritten.

2 - buffer used for echainiv(authenc) encrypt shared descriptor

Encrypt and givencrypt shared descriptors (for AEAD ops) are mutually
exclusive and thus use the same buffer in context state: sh_desc_enc.

However, there's one place missed by s/sh_desc_givenc/sh_desc_enc,
leading to errors when echainiv(authenc(...)) algorithms are used:
DECO: desc idx 14: Header Error. Invalid length or parity, or
certain other problems.

While here, also fix a typo: dma_mapping_error() is checking
for validity of sh_desc_givenc_dma instead of sh_desc_enc_dma.
