v3: https://lists.gnu.org/archive/html/qemu-devel/2017-09/msg04523.html
This patchset tries to reduce amount of memory used by FlatViews
and tries share as many FVs between address spaces as possible.
Changelog:
v4:
* total rework again to provide grounds for new 15/18, 17/18, 18/18
v3:
* addressed comments from v2, mainly simplified the code
v2:
* total rework
This is based on sha1
c51700273a Peter Maydell "Merge remote-tracking branch
'remotes/cohuck/tags/s390x-20170919-v2' into staging".
Please comment. Thanks.
