Subject: [PATCH v8 10/14] arm64/crypto: conditionally place ASM functions into separate sections
The resulting LD script generated by FG-KASLR script contains a size
assertion for the input .text function. In case if it's not empty,
the build will stop plug a potentional layout leakage.
As FG-KASLR for modules tends to be arch-independent, we should take
care of the modular ASM code of every architecture to not break the
build.
This is the ARM64 part.
