Thing is, CRYPTO_AES on only selectable on x86.

You're thinking about CRYPTO_AES_586. But looking at crypto/Kconfig, the dependencies are a bit weird:


config CRYPTO_AES
       tristate "AES cipher algorithms"
       depends on CRYPTO && !(X86 && !X86_64)
config CRYPTO_AES_586
       tristate "AES cipher algorithms (i586)"
       depends on CRYPTO && (X86 && !X86_64)


That's pretty broken, isn't it?

Would be better to just do:

config CRYPTO_AES
        select CRYPTO_AES_586 if (X86 && !X86_64)
        select CRYPTO_AES_OTHER if !(X86 && !X86_64)

and hide CRYPTO_AES_586 and CRYPTO_AES_OTHER from the outside world.

Not really that easy. For x86 we have

        aes
        aes-586
        aes-via


Where is aes-via?

drivers/crypto


And my own personal custom-kernel preference is to use the C version of the code on my x86 and x86-64 boxes.


That's already not possible today.

It should be.
