--- Comment #1 from Ard Biesheuvel <ardb at kernel dot org> ---
For 32-bit ARM, it would be useful to have
-mstack-protector-guard=tls
-mstack-protector-guard-offset=<offset>
and use gen_load_tp_hard() internally. As we also use the TLS register to index
other per-task data (using __builtin_thread_pointer()), we get better code this
way, since the compiler understands that there is no need to load the TLS
register multiple times in the same function.
