Revision b2665f92ae67a2d086537979d317a6f3a5697c63 authored by Matt Porter on 20 May 2005, 20:59:14 UTC, committed by Linus Torvalds on 20 May 2005, 22:48:19 UTC
This patch fixed CONFIG_TASK_SIZE handling on 44x. Currently head_44x.S hardcodes 0x80000000, which breaks if user chooses to change TASK_SIZE (e.g. for 3G user-space). Tested on Ocotea in 3G/1G configuration.
