It's fine, I'm the maintainer for asm-generic ;-)
All future architectures are required to do it the same way as
arm64 and use the generic syscall ABI. It just means we won't be
able to share this header with x86 or other architectures that
use a nonstandard string. We should have it in the generic place
even if arm64 is the only user for now.
