Patch 1 is the kernel part that provides the clue for user space tools to do this filtering. The other three parts are patches to tools that see the hint and act on it. Eric: Do you see a better way for the kernel that just crashed from a machine check to communicate the reason for the crash to the successor kernel? The Elf-note in vmcore needs quite a bit of code to set up - but is otherwise fairly succinct. We don't want the successor kernel to have to poke through too much memory from the crashed kernel to figure this out - the more we look at, the higher the probability that we step on the landmine that crashed the original kernel. -Tony
