v2: As suggested by Herbert Xu, the blocksize and alignmask checks have been moved to crypto_check_alg. So, now, all the other separate checks are not necessary. Also, the defines have been moved to include/crypto/algapi.h. v1: As suggested by Laura Abbott[1], I'm resending my patch with MAX_BLOCKSIZE and MAX_ALIGNMASK defined in an header, so they can be used in other places. I took this opportunity to deal with some other VLAs not handled in the old patch.
