[RFC PATCH for 4.18 0/2] Restartable Sequences selftests fixes

[RFC PATCH for 4.18 0/2] Restartable Sequences selftests fixes

[Mathieu Desnoyers]

Those are trivial restartable sequences selftest fixes for 4.18.

The executable flag of run_param_test.sh got lost in the merge of the
rseq patchset.

On ARM, align the struct rseq_cs definition in the inline asm to match
the alignment of that structure in the uapi headers.

Thanks,

Mathieu
