[PATCH for 4.18 0/3] rseq: minor fixes, cleanup

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

Hi Thomas,

Those are 2 small fixes, and a cleanup to the rseq feature, targeting
4.18.

The first fix takes care of an issue that arose in the integration of
the rseq patchset (executable bit on run_param_test.sh was lost). The
second fix aligns struct rseq_cs on 32 bytes on arm32, following the
rseq.h alignment requirements.

The last patch is a cleanup: given that we have decided that system
calls were not allowed in rseq critical sections, fork/clone cannot
be done in a rseq c.s.. Therefore, there is no need to abort a rseq
critical section within the child on fork of a new process.

Thanks,

Mathieu
