Ping?

What is the ping for ?

Ben.

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.

Thank you,
Bogdan P.

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.

v4:
- rebased on top of 3.19

v3:
- keep setting ENOSYS in syscall entry assembly when syscall tracing is disabled

v2:
- move setting ENOSYS from syscall entry assembly to do_syscall_trace_enter

Bogdan Purcareata (3):
    powerpc: Don't force ENOSYS as error on syscall fail
    powerpc: Relax secure computing on syscall entry trace
    powerpc: Enable HAVE_ARCH_SECCOMP_FILTER
