    selftests/powerpc: Add a test for PROT_SAO · 24af8c5a
    Michael Ellerman authored
    PROT_SAO is a powerpc-specific flag to mmap(), and we rely on arch
    specific logic to allow it to be passed to mmap().
    
    Add a small test to ensure mmap() accepts PROT_SAO. We don't have a good
    way to test that it actually causes the mapping to be created with the
    right flags, so for now we just touch the mapping so it's faulted in. In
    future we might be able to do something better.
