#     selftests/powerpc: Add test for pkey siginfo verification
#     
#     Commit c46241a370a61 ("powerpc/pkeys: Check vma before
#     returning key fault error to the user") fixes a bug which
#     causes the kernel to set the wrong pkey in siginfo when a
#     pkey fault occurs after two competing threads that have
#     allocated different pkeys, one fully permissive and the
#     other restrictive, attempt to protect a common page at the
#     same time. This adds a test to detect the bug.
