Log message:
bring in a few improvements from pedro, guenther, me...
thanks to krw@ for the original cherry-picking, millert@ for useful comment.
so:
- no longer expose internal kernel addresses, uses seq numbers instead
- make sure the numbers don't overflow (millert@ UINT64_MAX)... a
conservative estimate is that tmpfs will run out of seqs in >600 years...
- don't malloc dents, put them on the stack and zero them
- gc whiteout code
- gc getpage/putpage code (shrink uvm instead)
okay krw@, millert@
