Subject: s390: ignore pkey system calls
X-Git-Tag: v4.9-rc3~29^2~8

s390: ignore pkey system calls

Ignore the pkey systems calls since they don't make any sense on s390.
In addition any user could trigger a warning if issueing the pkey_free
system call, if it would be wired up on a system without pkey support.
