I wonder, if drivers end up calling this, isn't it easier to do the alignment in crypto_aead_ctx() directly? There are over 300 callers (not sure about the padding though, it may need still driver changes unless we can add it to something like crypto_tfm_alg_alignmask()). Or is the expectation that not all drivers need a DMA alignment?
I'm only changing the specific drivers that map things from the ctx structures for DMA. So it's not as bad as a simple grep would suggest.
