Again this statement.  I'm not against it as this is a true statement.

I really wonder how you can describe my intent with that statement 
though. We must be living in different universes.  This is so wrong as 
not to be funny anymore.

If you don't want to see my reply that's fine.  It'll be there for the 
posterity at least. If That's because you're just too proud to concede 
I'm right then this is very sad.

All I'm trying to tell you is that 6 *is* a "Completely made up number 
that you cannot explain" for user space and that's what we have right 
now in mainline for some ARM machines.

What I'm advocating for is a number that is _not_ completely made up.  
I'm advocating for a bogomips which meaning is well known and dates back 
to early Linux releases: the number of loops performed by the CPU during 
a jiffy, scaled to a second worth of jiffies, divided by 2 because there 
are 2 instructions in that loop.  Incidentally this very definition is 
the one you provided yourself in this thread. That's what I want, yet 
you qualify this as a "Completely made up number that you cannot 
explain".

Yeah right. I challenge you to quote anything I said in my previous 
email where I clearly explained everything in 6 points what I want. 
Anything you may quote to substantiate that statement of yours about 
what I want.  Everyone following this thread knows you can't.

But you probably didn't even read it. It might hurt too much.

Sheesh.
