Hi Linus,

Thanks for your review. I appreciated it.

I'm counting at least ten mistakes. Well my poor English should still improve 
in order to work on documentation.

I agree with you on all changes you are proposing, so I won't agree line by 
line. Instead I'll send a v3 and forward your tag. 

I have only a doubt and a questions. 
I'll jump directly to the relevant parts.

I was only able to use "Instead" to express that, contrary to the former 
conditions that is unexpected and uncommon, there are other expected and 
common causes of page faults. I thought that "Instead" stresses that the 
latter causes carry with them opposite and wanted consequences.

I think of "additionally" as a means to introduce less important and less 
frequently occurring conditions.

Nevertheless, I'll change it to "Additionally" as you are asking for.

Everything that follows from here onward should surely be changed as you are 
suggesting.

My only question is about why you prefer "kernel-internal" to a straight 
"kernel". Can you please say more about this?

I'll do the v3 _with_ the above suggestions.
