#     powerpc/rtas: mandate RTAS syscall filtering
#     
#     CONFIG_PPC_RTAS_FILTER has been optional but default-enabled since its
#     introduction. It's been enabled in enterprise distro kernels for a
#     while without causing ABI breakage that wasn't easily fixed, and it
#     prevents harmful abuses of the rtas syscall.
#     
#     Let's make it unconditional.
