rebase: backed out changeset 2519994d25ca

In the process of fixing issue5610 in 4.2.2, we are trying to backout
cf8ad0e6c0e4. This changesets is making changes that depends on cf8ad0e6c0e4,
so we need to back it out first.

Since issue5610 is pretty serious regression and the next stable release is a
couple of days away, we are taking the backout route until we can figure out
something better to do.
