[PATCH 0/5] Remove CRYPTO_ALG_ALLOCATES_MEMORY flag

[meenakshi . aggarwal]

From: Meenakshi Aggarwal <meenakshi.aggarwal@xxxxxxx>

This series includes patches to remove CRYPTO_ALG_ALLOCATES_MEMORY flag
and allocate the required memory within the crypto request object.

CRYPTO_ALG_ALLOCATES_MEMORY flag is limited only to dm-crypt use-cases,
which seems to be 4 entries maximum.
Therefore in reqsize we allocate memory for maximum 4 entries
for src and 1 for IV, and the same for dst, both aligned.
If the driver needs more than the 4 entries maximum, the memory
is dynamically allocated, at runtime.

Meenakshi Aggarwal (5):
  crypto:caam - avoid allocating memory at crypto request runtime for
    skcipher
  crypto:caam - avoid allocating memory at crypto request runtime for
    aead
  crypto: caam - avoid allocating memory at crypto request runtime for
    hash
  crypto: caam/qi - avoid allocating memory at crypto request runtime
  crypto: caam/qi2 - avoid allocating memory at crypto request runtime
