This set is an extension of a previous set called `crypto: qat - fix dm-crypt
related issues` which aims to re-enable the algorithms in the QAT driver
after [1].

This fixes a number of issues with the implementation of the QAT algs,
both symmetric and asymmetric.
In particular this set enables the QAT driver to handle correctly the
flags CRYPTO_TFM_REQ_MAY_BACKLOG and CRYPTO_TFM_REQ_MAY_SLEEP,
fixes an hidden issue in RSA and DH which appeared after commit f5ff79fddf0e,
related to the usage of dma_free_coherent() from a tasklet, and includes
important fixes in the akcipher algorithms.

One item to mention is that, differently from the previous set, this
one does not removes the flag CRYPTO_ALG_ALLOCATES_MEMORY which will
be removed after the conversation in [2] is closed.

[2] https://lore.kernel.org/linux-crypto/Yl6PlqyucVLCzwF5@silpixa00400314/

Changes from v2:
  - Removed `crypto: qat - set to zero DH parameters before free` from
    set.
  - Added fixes tags to patches `crypto: qat - add param check for RSA`
    and `crypto: qat - add param check for DH`

Changes from v1:
  - Clarified commit message in `crypto: qat - refactor submission logic`
    to indicate why the patch should be included in stable kernels
  - Removed `crypto: qat - use memzero_explicit() for algs` from set
    after feedback from Greg KH
  - Replaced memzero_explicit() with memset() in `crypto: qat - set to
    zero DH parameters before free` after feedback from Greg KH

Giovanni Cabiddu (10):
  crypto: qat - use pre-allocated buffers in datapath
  crypto: qat - refactor submission logic
  crypto: qat - add backlog mechanism
  crypto: qat - fix memory leak in RSA
  crypto: qat - remove dma_free_coherent() for RSA
  crypto: qat - remove dma_free_coherent() for DH
  crypto: qat - add param check for RSA
  crypto: qat - add param check for DH
  crypto: qat - honor CRYPTO_TFM_REQ_MAY_SLEEP flag
  crypto: qat - re-enable registration of algorithms

All applied.  Thanks.
