[PATCH v3 04/25] openrisc: head: use THREAD_SIZE instead of magic constant
From: Stafford Horne
Date: Tue Feb 21 2017 - 14:18:32 EST
From: Stefan Kristiansson <stefan.kristiansson@xxxxxxxxxxxxx>
The stack size was hard coded to 0x2000, use the standard THREAD_SIZE
definition loaded from thread_info.h.
