Otherwise modules that use these arithmetic operations will fail to link. We accomplish this with the usual EXPORT_SYMBOL, which on most architectures goes in the .S file but the ARM64 maintainers prefer that insead it goes into arm64ksyms. While we're at it, we also fix this up to use SPDX, and I personally choose to relicense this as GPL2||BSD so that these symbols don't need to be export_symbol_gpl, so all modules can use the routines, since these are important general purpose compiler-generated function calls.
