Hi,
this is a quick respin of the series with the kbuild test bot fixes and the
requested lm90 change.
Again, I think applying the RMI4 input driver needs the merge of the input tree

good.

Livepatch manages its own relocation sections and symbols in order to be
able to reuse module loader code to write relocations. This removes
livepatch's dependence on separate "dynrela" sections to write relocations
and also allows livepatch to patch modules that are not yet loaded.
