I could be wrong, but I thought files under uapi weren't supposed to 
contain __KERNEL__ code.  Wasn't that the whole point of uapi?

Also having the perf_event interface depend on endianess just seems like a 
complicated mess.  Can't we just declare the interface to be a certain 
endianess and have the kernel byte-swap as necessary?
