This set fixes a set of issues related to an improper use of the DMA APIs reported when CONFIG_DMA_API_DEBUG is selected and by the static analyzer Smatch. The first patch fixes an overlapping DMA mapping which occurs when in-place operations that share the same buffers but a different scatterlist structure are sent to the implementations of aead and skcipher in the QAT driver. The second commit reverts a patch that attempted to fix a warning reported by Smatch. This improperly reduced the mapping size for the region of memory used to store the input and output parameters that are passed to the FW for performing the RSA and DH algorithms. The last patch properly fixes the issues that the reverted commit attempted to fix.
