I just removed the comma in the end of those lists and resent the patch 
set as a "v3" and they are already seen in lore.
There is one strange thing though on lore. Some patch titles are not 
fully visible.

For sure the issue was comma in the end of To: or Cc: lists.
Not working example.
To: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, 
linux-usb@...r.kernel.org, linux-kernel@...r.kernel.org,

Working example.
To: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, 
linux-usb@...r.kernel.org, linux-kernel@...r.kernel.org

If the comma is at least in the end of one of those lists (To: or Cc:) 
vger.kernel.org mailing server will not accept them.

Artur
