It is correct to keep __IGNORE* entry in non uapi header asm/unistd.h while uapi/asm/unistd.h must hold information only useful for user space applications.

Hmm... There's also
#define __IGNORE_alarm #define __IGNORE_creat
Tell you what, I wouldn't mind if the following ones were actually implemented as syscalls in the kernel on Alpha:
#define __IGNORE_getegid #define __IGNORE_geteuid #define __IGNORE_getgid #define __IGNORE_getpid #define __IGNORE_getppid #define __IGNORE_getuid
There's a growing number of software packages that are deciding to sideskip glibc and call these syscalls directly. Supporting OSF's C ABI incompliant getxpid, etc., in such packages is not easy and rather intrusive.
