[PATCH v4 0/8] crypto: aes - retire table based generic AES

2017-07-18 Thread Ard Biesheuvel
The generic AES driver uses 16 lookup tables of 1 KB each, and has encryption and decryption routines that are fully unrolled. Given how the dependencies between this code and other drivers are declared in Kconfig files, this code is always pulled into the core kernel, even if it is usually
