The patch titled
Subject: kernel/panic.c: add TAINT_AUX
has been removed from the -mm tree. Its filename was
kernel-panic-add-taint_aux.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Borislav Petkov <bp@xxxxxxx>
Subject: kernel/panic.c: add TAINT_AUX
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.
