    SubjectRE: [Patch 1/4][kernel][slimdump] Add new elf-note of type NT_NOCOREDUMP to capture slimdump

    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.
