From 74f8f557fd0c6f32e17e78c9ef508ca66ef37d3a Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 4 Dec 2006 15:41:10 +0100 Subject: [PATCH] [S390] Don't use small stacks when lockdep is used. The lock dependency validator adds a bunch of extra stack frames to the stack, which can cause stack overflows. Especially seen on 31 bit where the small stack is only 4k.
