Hi,

here is the updated version of this series with these
changes:

- Removed sync_current_stack_to_mm() too.

- Added Acked-by's from Andy Lutomirski

The previous versions can be found here:

v1: https://lore.kernel.org/lkml/20200508144043.13893-1-joro@8bytes.org/

v2: https://lore.kernel.org/lkml/20200513152137.32426-1-joro@8bytes.org/

The cover-letter of v1 has more details on the motivation
for this patch-set.

Please review.

Regards,

Joerg
