This used to exist because in earlier versions of the system call interfaces, an "extern" declaration of the system call implementation function would precede the real inline version of the implementation. The compiler would not like this and would throw "static declaration of ‘foo’ follows non-static declaration". So alternate macros were needed which declare the implementation function as 'static inline' instead of extern. However, currently the inline version of these system call implementations appear first, the K_SYSCALL_DECLARE() macros appear in the header generated by gen_syscalls.py, which is always included at the end of the header file. The compiler does not complain if a static inline function is succeeded by an extern prototype of the same function. This lets us simplify the generated system call macros and just use __syscall everywhere. The disassembly of this was checked on x86 to ensure that for kernel-only or CONFIG_USERSPACE=n scenarios, everything is still being inlined as expected.
