Hi, This fixes up wchan which is various degrees of broken across the architectures. Patch 4 fixes wchan for x86, which has been returning 0 for the past many releases. Patch 5 fixes the fundamental race against scheduling. Patch 6 deletes a lot and makes STACKTRACE unconditional patch 7 fixes up a few STACKTRACE arch oddities 0day says all builds are good, so it must be perfect :-) I'm planning on queueing up at least the first 5 patches, but I'm hoping the last two patches can be too.
