Horia Geant? e7a7104e43 crypto: caam - make write transactions bufferable on PPC platforms
Previous change (see "Fixes" tag) to the MCFGR register
clears AWCACHE[0] ("bufferable" AXI3 attribute) (which is "1" at POR).

This makes all writes non-bufferable, causing a ~ 5% performance drop
for PPC-based platforms.

Rework previous change such that MCFGR[AWCACHE]=4'b0011
(bufferable + cacheable) for all platforms.
Note: For ARM-based platforms, AWCACHE[0] is ignored
by the interconnect IP.

Pull crypto fixes from Herbert Xu:
 "This fixes the following issues:

  API:
   - A large number of bug fixes for the af_alg interface, credit goes
     to Dmitry Vyukov for discovering and reporting these issues.

  Algorithms:
   - sw842 needs to select crc32.
   - The soft dependency on crc32c is now in the correct spot.

  Drivers:
   - The atmel AES driver needs HAS_DMA.
   - The atmel AES driver was a missing break statement, fortunately
     it's only a debug function.
   - A number of bug fixes for the Intel qat driver"

This will help to integrate the GCM support patch later by making the
difference between shared/common and specific code. Hence current
sections are:

- Shared functions: common code which will be reused by the GCM support.
- CPU transfer: handles transfers monitored by the CPU (PIO accesses).
- DMA transfer: handles transfers monitored by the DMA controller.
- AES async block ciphers: dedicated to the already supported block ciphers
- Probe functions: used to register all crypto algorithms.

Cyrille Pitchen bbe628ed89 crypto: atmel-aes - improve performances of data transfer
This patch totally reworks data transfer.

1 - DMA

The new code now fully supports scatter-gather lists hence reducing the
number of interrupts in some cases. Also buffer alignments are better
managed to avoid useless copies.

2 - CPU

The new code allows to use PIO accesses even when transferring more than
one AES block, so futher patches could tune the DMA threshold
(ATMEL_AES_DMA_THRESHOLD).
Moreover, CPU transfers now have a chance to be processed synchronously,
hence reducing the latency by avoiding context switches when possible
(less interrupts to process, less scheduling of the 'done' task).
Indeed the 'DATA READY' bit is polled only one time in the Interrupt
Status Register before enabling then waiting for the associated interrupt.
In some condition, this single poll is enough as the data have already
been processed by the AES hardware and so are ready.

Cyrille Pitchen ccbf72980b crypto: atmel-aes - make crypto request queue management more generic
This patch changes atmel_aes_handle_queue() to make it more generic.
The function argument is now a pointer to struct crypto_async_request,
which is the common base of struct ablkcipher_request and
struct aead_request.

Also this patch introduces struct atmel_aes_base_ctx which will be the
common base of all the transformation contexts.

Hence the very same queue will be used to manage both block cipher and
AEAD requests (such as gcm and authenc implemented in further patches).

Cyrille Pitchen cdfab4a7e3 crypto: atmel-aes - change atmel_aes_write_ctrl() signature
This patch changes the signature of atmel_aes_write_ctrl() to make it more
generic. This will be used by future patches when implementing new block
cipher modes such as GCM.

Especially atmel_aes_hw_init() is now called outside
atmel_aes_write_ctrl(): this allows to call atmel_aes_write_ctrl() many
times, still initializing the hardware only once.

Indeed, the support of GCM will require to update the Mode Register and
the IV when processing a single request.

Arnd Bergmann 75d3f811f3 crypto: sahara - fix 64-bit dma_addr_t compilation
The sahara hardware uses DMA descriptors with 32-bit addresses, but
dma_addr_t is variable size depending on whether we want to support
any devices that use 64-bit DMA addresses in hardware.
This means that the definition of the DMA descriptor structure is wrong,
and we helpfully get a compiler warning about them too:

drivers/crypto/sahara.c:423:372: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=]

This changes the definition of the sahara_hw_desc and sahara_hw_link
structures to only contain fixed-length members, which is required
to make the driver work on ARM LPAE mode, and avoids most of the
gcc warnings we get.

until we exit the kernel sometime later. Create disable versions
that wrap the kernel use of FP, Altivec VSX or SPE.

While we don't want to disable it normally for performance reasons
(MSR writes are slow), it will be used for a debug boot option that
does this and catches bad uses in other areas of the kernel.

Arnd Bergmann 56b85c9d7a crypto: atmel: fix bogus select
The Atmel at91 crypto driver unconditionally selects AT_HDMAC,
which results in a Kconfig warning if that driver is not enabled:

warning: (CRYPTO_DEV_ATMEL_AES) selects AT_HDMAC which has unmet direct dependencies (DMADEVICES && ARCH_AT91)

The crypto driver itself does not actually have a dependency
on a particular dma engine, other than this being the one that
is used in at91.

Removing the 'select' gets rid of the warning, but can cause
the driver to be unusable if the HDMAC is not enabled at the
same time. To work around that, this patch clarifies the runtime
dependency to be 'AT_HDMAC || AT_XDMAC', but adds an alternative
for COMPILE_TEST, which lets the driver get build on all systems.

The ARCH_AT91 dependency is implied by AT_XDMAC || AT_HDMAC now
and no longer needs to be listed separately.

Arnd Bergmann 20ecae79e7 crypto: atmel - fix 64-bit warnings
The atmel AES driver assumes that 'int' and 'size_t' are the same
type in multiple locations, which the compiler warns about when
building it for 64-bit systems:

In file included from ../drivers/crypto/atmel-aes.c:17:0:
drivers/crypto/atmel-aes.c: In function 'atmel_aes_sg_copy':
include/linux/kernel.h:724:17: warning: comparison of distinct pointer types lacks a cast
drivers/crypto/atmel-aes.c:448:11: note: in expansion of macro 'min'

drivers/crypto/atmel-aes.c: In function 'atmel_aes_crypt_dma_stop':
include/linux/kern_levels.h:4:18: warning: format '%u' expects argument of type 'unsigned int', but argument 2 has type 'size_t {aka long unsigned int}' [-Wformat=]

This changes the format strings to use the %z modifier when printing
a size_t, and makes sure that we use the correct size_t type where
needed. In case of sg_dma_len(), the type of the result depends
on CONFIG_NEED_SG_DMA_LENGTH, so we have to use min_t to get it to
work in all configurations.
