Add a struct irq_affinity pointer to the find_vqs methods, which if set
is used to tell the PCI layer to create the MSI-X vectors for our I/O
virtqueues with the proper affinity from the start. Compared to after
the fact affinity hints this gives us an instantly working setup and
allows to allocate the irq descritors node-local and avoid interconnect
traffic. Last but not least this will allow blk-mq queues are created
based on the interrupt affinity for storage drivers.

This patch introduces a new in-kernel-crypto blockcipher
called 'paes' which implements AES with protected keys.
The paes blockcipher can be used similar to the aes
blockcipher but uses secure key material to derive the
working protected key and so offers an encryption
implementation where never a clear key value is exposed
in memory.
The paes module is only available for the s390 platform
providing a minimal hardware support of CPACF enabled
with at least MSA level 3. Upon module initialization
these requirements are checked.
Includes additional contribution from Harald Freudenberger.

This patch introcudes a new kernel module pkey which is providing
protected key handling and management functions. The pkey API is
available within the kernel for other s390 specific code to create
and manage protected keys. Additionally the functions are exported
to user space via IOCTL calls. The implementation makes extensive
use of functions provided by the zcrypt device driver. For
generating protected keys from secure keys there is also a CEX
coprocessor card needed.

If we register the DMA API debug notification chain to
receive platform bus events:
dma_debug_add_bus(&platform_bus_type);
we start receiving warnings after a simple test like "modprobe caam_jr &&
modprobe caamhash && modprobe -r caamhash && modprobe -r caam_jr":
platform ffe301000.jr: DMA-API: device driver has pending DMA allocations while released from device [count=1938]
One of leaked entries details: [device address=0x0000000173fda090] [size=63 bytes] [mapped with DMA_TO_DEVICE] [mapped as single]
It turns out there are several issues with handling buf_dma (mapping of buffer
holding the previous chunk smaller than hash block size):
-detection of buf_dma mapping failure occurs too late, after a job descriptor
using that value has been submitted for execution
-dma mapping leak - unmapping is not performed in all places: for e.g.
in ahash_export or in most ahash_fin* callbacks (due to current back-to-back
implementation of buf_dma unmapping/mapping)
Fix these by:
-calling dma_mapping_error() on buf_dma right after the mapping and providing
an error code if needed
-unmapping buf_dma during the "job done" (ahash_done_*) callbacks

In case ctx_dma dma mapping fails, ahash_unmap_ctx() tries to
dma unmap an invalid address:
map_seq_out_ptr_ctx() / ctx_map_to_sec4_sg() -> goto unmap_ctx ->
-> ahash_unmap_ctx() -> dma unmap ctx_dma
There is also possible to reach ahash_unmap_ctx() with ctx_dma
uninitialzed or to try to unmap the same address twice.
Fix these by setting ctx_dma = 0 where needed:
-initialize ctx_dma in ahash_init()
-clear ctx_dma in case of mapping error (instead of holding
the error code returned by the dma map function)
-clear ctx_dma after each unmapping

setkey() callback may be invoked multiple times for the same tfm.
In this case, DMA API leaks are caused by shared descriptors
(and key for caamalg) being mapped several times and unmapped only once.

cra_init() / cra_exit() callbacks and sync_for_device in the setkey()

HW S/G generation does not work properly when the following conditions
are met:
-src == dst
-src/dst is S/G
-IV is right before (contiguous with) the first src/dst S/G entry
since "iv_contig" is set to true (iv_contig is a misnomer here and
it actually refers to the whole output being contiguous)

leaving it set to init value (0).

This patch clarifies and fixes how errors should be handled by
atmel_sha_start().
For update operations, the previous code wrongly assumed that
(err != -EINPROGRESS) implies (err == 0). It's wrong because that doesn't
take the error cases (err < 0) into account.
This patch also adds many comments to detail all the possible returned
values and what should be done in each case.
Especially, when an error occurs, since atmel_sha_complete() has already
been called, hence releasing the hardware, atmel_sha_start() must not call
atmel_sha_finish_req() later otherwise atmel_sha_complete() would be
called a second time.

This patch fixes a previous patch: "crypto: atmel-sha - update request

Indeed the patch above should have replaced the "return -EINVAL;" lines by
"return atmel_sha_complete(dd, -EINVAL);" but instead replaced them by a
simple call of "atmel_sha_complete(dd, -EINVAL);".
Hence all "return" instructions were missing.

With the new authenc support, we get a harmless Kconfig warning:
warning: (CRYPTO_DEV_ATMEL_AUTHENC) selects CRYPTO_DEV_ATMEL_SHA which has unmet direct dependencies (CRYPTO && CRYPTO_HW && ARCH_AT91)
The problem is that each of the options has slightly different dependencies,
although they all seem to want the same thing: allow building for real AT91
targets that actually have the hardware, and possibly for compile testing.
This makes all four options consistent: instead of depending on a particular
dmaengine implementation, we depend on the ARM platform, CONFIG_COMPILE_TEST
as an alternative when that is turned off. This makes the 'select' statements
work correctly.
