First off, the last version I've seen is the v3.  I must have overlooked
the v4 then, but I don't think it was CCed to linux-acpi (which should
have happened).

Second, these patches require review from multiple maintainers and (or including)
people who actually know how the GTDT is supposed to be used.  I haven't
seen any responses from any of them yet, so the answer to your question is
"yes".

I will have a couple of comments for patch [1/6] (in the v3), but it's
not been a priority due to the apparent overall lack of interest in this
series.

Thanks,
