Vinod, Pierre, could you guys check these patches?

If these are OK, I can still merge for 3.10.  Although it's already
late for 3.10, there are little users of compress stuff, so the impact
must be fairly small.  If you guys aren't still happy, let's postpone
for 3.11.


If we really merge it, don't you mind me merging soc-compress patch in
my tree (directly to for-next branch), Mark?


thanks,

Takashi
