What is the ping for ?


Making sure the patches are not lost on the mailing lists :) Didn't receive any feedback on v4 and just wanted to check if there's anything more I can do.

Add the missing pieces in order to enable SECCOMP_FILTER on PowerPC
architectures, and enable this support.

Testing has been pursued using libseccomp with the latest ppc support patches
[1][2], on Freescale platforms for both ppc and ppc64. Support on ppc64le has
also been tested, courtesy of Mike Strosaker.


- rebased on top of 3.19

- keep setting ENOSYS in syscall entry assembly when syscall tracing is disabled

- move setting ENOSYS from syscall entry assembly to do_syscall_trace_enter

powerpc: Don't force ENOSYS as error on syscall fail
powerpc: Relax secure computing on syscall entry trace
