[rfc linux-next 0/3] prctl: prctl_set_mm -- Bring back handling of PR_SET_MM_x

[Cyrill Gorcunov]

Hi! Yesterday I've been pointed out that we unfortunatelly can't
drop off PR_SET_MM_x operations. So here is a series which bring
them back but instead of plain revert I tried to simplify the
code and make it as minimum as possible.

WARN: the series is compile-tested only for a while, I wanted
to share it early so maybe someone has better idea of how
integrate old PR_SET_MM_x operations. I'll do full tests
today hopefully.
