Whilst linux-next now contains the EDAC patches, we shouldn't base
a feature submission on it.  This should be the same as you
did for the CXL tree with a statement that it depends on 

https://web.git.kernel.org/pub/scm/linux/kernel/git/ras/ras.git/log/?h=edac-cxl

which is the immutable tag / branch Borislav provided.

I doubt there is anything else hitting this code so
shouldn't be any need to rebase (I could be wrong though!)

Assuming everyone is happy with this series, who is going to pick
it up?

Borislav via ras.git, or Rafael via acpi.git?  I don't really
have any preference other than making sure it doesn't fall down
the cracks!
