It's "aggressive" in that many dependent patches are finally being
properly found and backported as needed to be able to get the "real" fix
applied properly.  That's all, nothing odd here, and all of these
commits have been through proper review and development and acceptance
already, so it's not like they are brand new things, they are required
for real fixes.

Again, we want to keep as close as possible with Linus's tree because
ALMOST EVERY time we try to do our own thing, we get something wrong.
Keeping in sync is essencial to rely on our overall testing and future
fix ability to keep in sync properly.

To attempt to do "one off" backports all over the place just does not
work, we have tried it and failed.  To not accept the fix at all leaves
us vulnerable to a known bug, why would that be ok?

Change is good, and these changes are extra-good as they fix things.

thanks,
