Yes, but these commits refer to the AdoptOpenJDK Git mirror [1] of the
upstream Mercurial repository [2]. src:openjdk-11 pulls directly from
Mercurial but the source tree is identical.

Yes, DCEVM picks a patch from openjdk-11 to support multi arch libraries
[3]. The other patches are not relevant to DCEVM.

The source is the same, but DCEVM builds only the HotSpot VM, not the
Java standard library nor the developer tools. DCEVM just swaps the JVM
at runtime, everything else is provided by openjdk-11, that's why the
two packages are tightly coupled.
I can confirm that the delta between both sources is exactly the patch set.

You are right sorry, I meant the commit ranges as inclusive but that's
not how "git diff" works. The 10 new commits actually change +222/-17
lines [4].
