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.
