I can review this series from the build system point of view,
but I am not familiar enough with live-patching itself.
Some possibilities:
[1] Merge this series thru the live-patch tree after the
kbuild base patches land.
This requires one extra development cycle (targeting for 5.5-rc1)
but I think this is the official way if you do not rush into it.
[2] Create an immutable branch in kbuild tree, and the live-patch
tree will use it as the basis for queuing this series.
We will have to coordinate the pull request order, but
we can merge this feature for 5.4-rc1
[3] Apply this series to my kbuild tree, with proper Acked-by
from the livepatch maintainers.
I am a little bit uncomfortable with applying patches I
do not understand, though...
