#     selftests/powerpc: Add a test of sigreturning to the kernel
#     
#     We have a general signal fuzzer, sigfuz, which can modify the MSR & NIP
#     before sigreturn. But the chance of it hitting a kernel address and also
#     clearing MSR_PR is fairly slim.
#     
#     So add a specific test of sigreturn to a kernel address, both with and
#     without attempting to clear MSR_PR (which the kernel must block).
