From b20947aaa0026efd7355ae4bf70b56a13a3f98b1 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Wed, 21 Apr 2010 22:36:47 +0200 Subject: MIPS: Fixup screen_info struct initializations |arch/mips/sibyte/swarm/setup.c:153: | warning: large integer implicitly truncated to unsigned type The field was changed in d9b26352 aka ("x86, setup: Store the boot cursor state"). This patch changes the values back they way they were before this extra field got introduced. While here, the other two boards are also converted to C99 initializer.

The option changes all of the jump target to "addr & 0xcfffffff" through the at($1) register, but for the reboot address of Loongson 2F 0xbfc00000 this is wrong. Avoids the problem via telling the assembler to not use the $at register.
