[PATCH v4 0/3] powerpc: Enable seccomp filter support

From: Bogdan Purcareata
Date: Wed Feb 18 2015 - 03:33:06 EST

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

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