Linus,
	I'm going to withdraw the revert request for now.  Our proposed
paper-over solution is too big, and we're just going to focus on the
actual fix.  This will be for .35.  Yes, .35-rc will have a BUG_ON with
refcount trees until we get the fix in, but I'd rather avoid the churn
when the final .35 should have Dave's patch and our fix.
