Subject: powerpc: Ignore the pkey system calls for now
X-Git-Tag: v4.9.8~866^2~25
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=78914ff0843623ee6dbeae92fa0bb8761828684e;p=platform%2Fkernel%2Flinux-rpi3.git

powerpc: Ignore the pkey system calls for now

Eliminates warning messages:

<stdin>:1316:2: warning: #warning syscall pkey_mprotect not implemented [-Wcpp]
<stdin>:1319:2: warning: #warning syscall pkey_alloc not implemented [-Wcpp]
<stdin>:1322:2: warning: #warning syscall pkey_free not implemented [-Wcpp]

Hopefully we will remember to revert this commit if we ever implement
them.
