[ add Boris and Ard ] Ard, Boris, can you have a look at the touches to early e820/x86 init (insert_resource_late()) and give an ack (or nak). The general problem here is conflicts between e820 memory resources and CXL subsystem memory resources.

Otherwise plain Signed-off-by is interpreted as only chain of custody. Any other patches that you add my Signed-off-by to should also have Co-developed-by or be From: me. Alternatively if you completely rewritel a patch with your own approach then note the source (with a Link:) and leave off the original SOB. Lastly, in this case it looks unmodified from what I wrote? Then it should be: From: Dan Williams <dan.j.williams@xxxxxxxxx> Signed-off-by: Dan Williams <dan.j.williams@xxxxxxxxx> Signed-off-by: Smita Koralahalli <Smita.KoralahalliChannabasappa@xxxxxxx> ...to show the chain of custody of you forwarding a diff authored completely by someone else.
