glibc has a fallback in the form of the syscall() function, which can be used to invoke any syscall without the need for a wrapper, e.g.

    syscall(SYS_getcpu, &cpu, &node, NULL);

It means you don't have to deal with the kernel's calling conventions, which are architecture-specific and require inline assembly.
