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!

[PATCH] remove all kernel BUGs This patch eliminates all kernel BUGs, trims about 35k off the typical kernel, and makes the system slightly faster. Signed-off-by: Matt Mackall <mpm@selenic.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

[PATCH] s390: BUG() warnings Use __builtin_trap instead of an inline assembly in the BUG() macro. That way the compiler knows that BUG() won't return.

[S390] __builtin_trap() and gcc version. __builtin_trap() has the archictecture defined backend in gcc since gcc 3.3. To make sure the kernel builds with gcc 3.2 as well, use the old style BUG() statement if compiled with older gcc versions.
