Subject: [PATCH v2 0/3] powerpc: Enable seccomp filter support

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], on Freescale platforms for both ppc and ppc64. ppc64le support is
untested.

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
