v1: https://lore.kernel.org/lkml/20200912110820.597135-1-keescook@chromium.org
- Took Acked patches into -next
- refactored powerpc syscall setting implementation
- refactored clone3 args implementation


This finishes the refactoring of the seccomp selftest logic used in
for ptrace syscall number/return handling for powerpc. Additionally
fixes clone3 (which seccomp depends on for testing) to run under MIPS
where an old struct clone_args has become visible.

(FWIW, I expect to take these via the seccomp tree.)


Kees Cook (4):
  selftests/seccomp: Record syscall during ptrace entry
  selftests/seccomp: Allow syscall nr and ret value to be set separately
  selftests/seccomp: powerpc: Set syscall return during ptrace syscall
  selftests/clone3: Avoid OS-defined clone_args
