| H A D | .gitignore | a8968521 Thu Dec 09 05:59:44 CST 2021 Michael Ellerman <mpe@ellerman.id.au> 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).
