PSA: migrating linux-api to new vger infrastructure

Good day!

I plan to migrate the linux-api@vger.kernel.org list to the new infrastructure
this week. We're still doing it list-by-list to make sure that we don't run
into scaling issues with the new infra.

The migration will be performed live and should require any downtime.

Please speak up if you have any objections.

Best wishes,
