Then what is the plan for 4.1+ ?

Are you still going to use kaslr_setup_data?
If if is YES, then we should have
patch1: https://lkml.org/lkml/2015/3/15/7
patch2:
f47233c2d34f243ecdaac179c3408a39ff9216a7 + fix from
https://lkml.org/lkml/2015/3/15/8

If you are not going to have setup_data and
f47233c2d34f243ecdaac179c3408a39ff9216a7
back, please let me know.
I may need to change patch in  https://lkml.org/lkml/2015/3/15/7,
So it only have ADDON_ZO_SIZE with pgtable only and
we can go on with kaslr on 64bit above 4G support.

Thanks
