lkml.org is pretty worthless for this sort of thing, and lkml.kernel.org
is the preferred link method in general. The syntax is
https://lkml.kernel.org/r/<Message-ID>
e.g.
https://lkml.kernel.org/r/20200205181935.3712-1-yu-cheng.yu@intel.com
Note, that will redirect to lore.kernel.org, but the above format is
preferred because it isn't dependent on binning the thread to a specific
mailing list.
Anyways, kernel.org provides a link to download the entire thread in mbox
format, which allows reviewers to get the prerequisite series without much
fuss.
