applied to tip/x86/core, thanks Yinghai. Lets hope it all goes well, 
this is a rather scary change - but it's also fairly clean.

perhaps add a comment to the limit of 5 of mapping ranges - to point out 
that the number of mapping ranges depends on our programming, not on any 
external factor. I.e. if anyone adds a new mapping range to the kernel 
for any purpose, it must be extended - but otherwise it cannot run out 
due to new hardware.
