The sahara driver use two dma_map_sg path according to SG are chained or not. Since dma_map_sg can handle both case, clean the code with all references to sg chained. Thus removing the sahara_sha_unmap_sg function. Signed-off-by:

Some code cleanups after crypto API changes: - Change qat_algs_unregister to a void function to keep it consistent with qat_asym_algs_unregister. - Remove empty functions qat_algs_init & qat_algs_exit. Signed-off-by:

Module crc32c-intel uses a special read-only data section named .rotata. This section is defined for K_table, and its name seems to be a spelling mistake for .rodata. Fixes: 473946e6 ("crypto: crc32c-pclmul - Shrink K_table to 32-bit words") Signed-off-by:

Restructure the x86 sha512 glue code so we will expose sha512 transforms based on SSSE3, AVX or AVX2 as separate individual drivers when cpu provides support. This will make it easy for alternative algorithms to be used if desired and makes the code cleaner and easier to maintain. Signed-off-by:

If we attempt to use sysfs to change the current RNG in the usual way i.e. issuing something like: `echo 8a8a000.rng > /sys/devices/virtual/misc/hw_random/rng_current` ... it will fail because the code doesn't currently take the '\n' into consideration. Well, now it does. Signed-off-by:

In April 2009, commit d4056405 ("Driver Core: misc: add node name support for misc devices.") inadvertently changed the device node name from /dev/hw_random to /dev/hwrng. Since 6 years has passed since the change it seems unpractical to change it back, as this node name is probably considered ABI by now. So instead, we'll just change the Kconfig help to match the current situation. NB: It looks like rng-tools have already been updated. Signed-off-by:

Load balancing of crypto instances only used a single device. There was no problem with that on PF, but since there is only one or two instance per VF we need to loadbalance across devices. Signed-off-by:

Commit a1efb01f ("jump_label, locking/static_keys: Rename JUMP_LABEL_TYPE_* and related helpers to the static_key* pattern") introduced the definition of JUMP_TYPE_MASK in include/linux/jump_label.h causing the following name collision: In file included from drivers/crypto/caam/desc_constr.h:7:0, from drivers/crypto/caam/ctrl.c:15: drivers/crypto/caam/desc.h:1495:0: warning: "JUMP_TYPE_MASK" redefined #define JUMP_TYPE_MASK (0x03 << JUMP_TYPE_SHIFT) ^ In file included from include/linux/module.h:19:0, from drivers/crypto/caam/compat.h:9, from drivers/crypto/caam/ctrl.c:11: include/linux/jump_label.h:131:0: note: this is the location of the previous definition #define JUMP_TYPE_MASK 1UL As JUMP_TYPE_MASK definition in desc.h is never used, we can safely remove it to avoid the name collision.

The output buffer in test_ahash_speed will point to an address located within the tcrypt module image. This causes problems when trying to DMA map the buffer.
