Ok, I'll wait for a new patch set.  

Another direction that you might consider is to check whether
a new symbol was introduced in the same patch-set that
incremented the PERCPU_SHIFT values?

Or take Keir up on his offer to compile-in an absolute
value that can be accessed like a symbol?

As far as the UPTIME display, it will probably raise
fewer questions in the future if you would just remove
it entirely. 

Thanks,
