Raw Normal View History

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!

[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.
