From a4b5177ca83ca97c562a7138923dafe0cb92d1a0 Mon Sep 17 00:00:00 2001 From: Marcin Kościelnicki Date: Thu, 14 Jan 2016 16:48:55 +0100 Subject: Add __private_ss to s390 struct tcbhead. 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.
