Should probably say why when doing a rebase to something other than rc1.
In this case this is what cxl.git/next is based on after some fixes earlier
in the cycle so a sensible choice for this set.

As far as I'm concerned this set is ready to go, but more eyes always good
if anyone has time! Same for the ras-daemon series once this is queued for
the kernel.
