    kernel/panic.c: add TAINT_AUX · 4efb442c
    Borislav Petkov authored
    This is the gist of a patch which we've been forward-porting in our
    kernels for a long time now and it probably would make a good sense to
    have such TAINT_AUX flag upstream which can be used by each distro etc,
    how they see fit.  This way, we won't need to forward-port a distro-only
    version indefinitely.
    Add an auxiliary taint flag to be used by distros and others.  This
    obviates the need to forward-port whatever internal solutions people
    have in favor of a single flag which they can map arbitrarily to a
    definition of their pleasing.
    The "X" mnemonic could also mean eXternal, which would be taint from a
    distro or something else but not the upstream kernel.  We will use it to
    mark modules for which we don't provide support.  I.e., a really
    eXternal module.
