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.
