btw., did you actually see a boot crash due to this, on a pre-PGE system?
   
      
 
No, under Xen, since it also disables PGE.
     
 
 but it was a boot crash, right? Such info is useful in the first line of a 
commit message:
  Impact: fix non-PGE boot crash
(that also makes it less likely that the commit is under-prioritized.)
 
 
 It's not immediate; in early usermode.  It only happens when using a 
populated PROTNONE page, which is actually pretty rare, it seems - 
perhaps made more common by the new mlock code.  But, yes, it stopped my 
machine from booting.
