Enable Adiantum crypto as module for x86 & x86_64 kernels
Adiantum is a crypto cipher typically used for low powered systems (i.e. Arm SBCs).
However it would be useful for this to be enabled as a kernel module (CONFIG_CRYPTO_ADIANTUM=m) for x86 and x86_64 kernels (both linux-lts and linux-virt) so that such encrypted partitions could be mounted on x86/x86_64 machines.
