In uapi/asm/auxvec.h you conditionalize the ADI aux vectors on
CONFIG_SPARC64.

That's not correct, you should never control user facing definitions
based upon kernel configuration.

Also, both 32-bit and 64-bit applications running on ADI capable
machines want to compile against and use this informaiton.

So please remove these CPP checks.


Hi Dave,

That makes sense. I will send a patch to remove these.

Thanks,
Khalid
