For bigger patchsets, you should combine get_maintainer.pl with sending
emails so individual patches will go to all role-based entries from
get_maintainer.pl and to all mailing lists. You can (and sometimes even
worth to) skip proposals based on git-history.

Then the cover letter which should go to everyone... or most of people
and linked from individual patches.

For example the easiest I think:
1. Put all folks and lists as "Cc:" in cover letter.
2. Send everything:
   git send-email --cc-cmd "scripts/get_maintainer.pl --no-git --no-roles --no-rolestats" --to linux-kernel@vger.kernel.org 0*

Optionally you could add --no-git-fallback to get_maintainer if it
proposes some irrelevant addresses.

Other way is to send first cover letter and then reference it via
in-reply-to:

1. To get everyone for cover letter:
   scripts/get_maintainer.pl --no-multiline --interactive --separator=\'' --to '\' --no-git --no-roles --no-rolestats 00*

2. git send-email --cc linux-kernel@vger.kernel.org ... 0000*

3. Finally all patches with in-reply-to:
   git send-email --cc-cmd "scripts/get_maintainer.pl --no-git --no-roles --no-rolestats" --to linux-kernel@vger.kernel.org --no-thread --in-reply-to='foo-bar-xxxxxxx' 000[123456789]-* 00[123456789]*-*
