[PATCH v2 for 4.18 0/6] Restartable Sequences updates

[Mathieu Desnoyers <mathieu.desnoyers@efficios.com>]

Following the recent discussion thread [1] about rseq uapi, here is
a set of updates submitted for integration into 4.18. Those change all
rseq __get_user/__put_user for get_user/put_user as discussed, and
use copy_from_user()/clear_user() to load and clear the rseq_cs __u64.

Thanks,

Mathieu
