powerpc: cpuset: add local functions for copyin/copyoutHEADmain
Add local functions to workaround an instruction segment trap (panic) when the indirect functions copyin and copyout are called by an external loadable kernel module (i.e. pfsync, zfs and linuxulator). The crash was triggered by change 47a57144af25a7bd768b29272d50a36fdf2874ba, but kernel binary linked with LLD 9 works fine. LLVM bisect points that LLD behavior chaged after dc06b0bc9ad055d06535462d91bfc2a744b2f589. This is know to affect powerpc targets only and the final fix is still being discussed with the LLVM community.
