I've pushed an x86-cpuid-db release about an hour after receiving Maciej's
patch.  And that was mostly because of adding more fixes in the same spirit
as Maciej's findings.

So I would suggest a "wait and see" approach.  I don't think that the
frequency of adding new bits or fixes to the database will be that high.

There is also a git-describe tag on top of leaf_types.h and kcpuid.csv.
The idea was to encourage people that submitted kernel patches touching
these files are either from a pushed x86-cpuid-db release or at least from
its tip branch.

I'm definitely biased here, but I'm optimistic that this can smoothly work
out.  In the end, the x86 maintainers still hold all the keys here, in the
sense that there is no risk of slowing down anything, especially in
emergency cases (say a new HW vulnerability.)

Thanks!
