- Subject: [PATCH] Add __private_ss to s390 struct tcbhead.
- Authentication-results: sourceware.org; auth=none
Preparation for gcc -fsplit-stack support (gcc bug #68191). The new
field is basically identical to the one on x86. Its TCB offset needs
to be constant, as it'll be hardcoded in gcc.
* sysdeps/s390/nptl/tls.h: Add __private_ss to struct tcbhead.
