[PATCH RESEND 0/3] selftests: Skip SUD tests when unsupported

[Christian Loehle]

Hi Shuah,
the series is a resend which has picked up all the relevant tags
and is ready to apply!

Syscall User Dispatch (SUD) is unavailable on architectures without
generic syscall entry. Such architectures return -EINVAL for otherwise
valid SUD prctl and ptrace requests, which the SUD selftests currently
report as failures.

Probe SUD with a valid disabled configuration and skip the affected tests
when that probe returns EINVAL. Unexpected errors remain failures, and the
existing coverage is unchanged on kernels that support SUD.
