The features and locked registers hold the same bits, the latter is a lock for the former. Tested with core files and live processes. I thought about setting a non-zero lock register in the core file, however: * We can be pretty sure it's reading correctly because its between the 2 other GCS registers in the same core file note. * I can't make the test case modify lock bits because userspace can't clear them (without using ptrace) and we don't know what the libc has locked (probably all feature bits).
