That is also fine. I can update in v4.
Paul, Do you have any comment on this and could you confirm user
space doesn't need this macros - __NR_N32/N64/O32_Linux,
__NR_N32/N64/O32_Linux_syscalls ?

Ah, you catch this one.I thought it will go with out notice.
Ok, I create one more patch in my v4.

Paul, FYI, you asked me to convert 64 to n64. Here I'm changing file
name - scall64-n64.S (previously it was scall64-64.S) also.

Thanks
