From 0778dc3a624b48cf80072b04405cacd1ad4079be Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Thu, 27 Nov 2008 11:05:58 +0100 Subject: [PATCH] [S390] Fix alignment of initial kernel stack. We need an alignment of 16384 bytes for the initial kernel stack if the kernel is configured for 16384 bytes stacks but the linker script currently guarantees only an alignment of 8192 bytes. So fix this and simply use THREAD_SIZE as alignment value which will always do the right thing.
