 Nope, it's not under arch/mips/include/uapi/, but this is a common MIPS 
header used across many projects (see the copyright notices at the top 
going back to 1985), so there has been no sense to make Linux-specific 
changes to it just for the sake of it given that it works as it stands.  
Don't fix what ain't broke.  Don't make changes just because you can.
