treewide: License cleanup - RedHat originated

[Thomas Gleixner]

Richard!

Sorry for pestering you, but the amount of files is just too much to split
it up and targetting the authors is difficult because quite some of them
are not longer at RHT. The files are all (c) RedHat or Sistina Software,
which is part of RedHat since 2003.

This is part of the effort to clean up the licensing mess in the kernel and
convert it to SPDX license identifiers as the only source of license
information.

Archaeology found the following unspecific GPL license references, which
have been authored by RedHat/Sistina.

To clean this up, can you please either advise the RHT kernel team or let
me know which GPLv2 variant to use for the files and I run it through my
cleanup machinery.

Thanks,

	Thomas

Hi Thomas,

I assume you're selecting files that have some sort of Red Hat or
Sistina copyright notice. Just as a disclaimer, I can't speak to
copyrights in these files that may be held by other organizations or
individuals (and I can't say definitively whether any file bearing a
Red Hat or Sistina copyright notice has or retains any copyright owned
by Red Hat). With that said:

> 1) this file is released under the gpl

I am fine with saying that any Red Hat copyrights (including any
Sistina copyrights acquired by Red Hat) in these can be represented
with SPDX-License-Identifier: GPL-2.0.

I would note that the following files did not seem to have any Red Hat
or Sistina copyright notices:

Skipping category 2 for the moment:

I am fine with saying that any Red Hat copyrights (including any
Sistina copyrights acquired by Red Hat) in these can be represented
with SPDX-License-Identifier: GPL-2.0.

For these, if the question is just about what version of the LGPL we
should treat these as, I'd be fine with representing them as
SDPX-License-Identifier: LGPL-2.1.

However, and I realize this may go beyond my 'remit' as someone
consulted for linux-spdx stuff or open some additional bag of worms,
I'm wondering if these would be better off just relicensed under
GPLv2, and thus represented as SPDX-License-Identifier: GPL-2.0. Even
treating this code as having been LGPLv2.x-licensed, this would be
authorized or at any rate contemplated by the largely-overlooked
LGPLv2.0/LGPLv2.1 section 3. Suggesting this because it would seem to
help marginally with some of the goals of this initiative and also
because it's not obvious to me why LGPL would have been preferred over
GPLv2 for these files to begin with, assuming they weren't copied from
some unrelated LGPL-licensed project. I've cc'd Jonathan Brassow and
Mike Snitzer in case they have any thoughts on this.

Oops, yes. They are clearly flagged as not Red Hat.

Hi Thomas, yes I'd love for you to take on the changes to run through
your machinery.  I think we have consensus in that I agree with
everything Richard has said.  Proposed changes look good, thanks!

Thanks for bringing me in the loop.  I appreciate it.
Right,  No real need for LGPL here (that I'm aware of).

True, though Red Hat has contributed code to these files and continues
to mainatin these files.

If we need further approval from original authors I can work to reach
out to them.
