Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip! 2005-04-16 22:20:36 +00:00			`#ifndef __ASM_BUG_H`

[MIPS] Use conditional traps for BUG_ON on MIPS II and better. This shaves of around 4kB and a few cycles for the average kernel that has CONFIG_BUG enabled. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> 2006-10-16 00:38:50 +00:00			`#include <asm/sgidefs.h>`

[MIPS] Fix BUG(), BUG_ON() handling With commit 63dc68a8cf60cb110b147dab1704d990808b39e2, kernel can not handle BUG() and BUG_ON() properly since get_user() returns false for kernel code. Use __get_user() to skip unnecessary access_ok(). This patch also make BRK_BUG code encoded in the TNE instruction.
