RoFL. Now as you said it I... noticed it at all... (*sigh*, the curse of
automation) and I absolutely agree with you. But I've literally no idea...

Subject: [PATCH] Replace HTTP links with HTTPS ones: XDP (eXpress Data Path)

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
   If not .svg:
     For each line:
       If doesn't contain `\bxmlns\b`:
         For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
             If both the HTTP and HTTPS versions
             return 200 OK and serve the same content:
               Replace HTTP with HTTPS.

     This is Intel's standard reference platform for the IXDP425 and is
     also known as the Richfield board. It contains 4 PCI slots, 16MB
     of flash, two 10/100 ports and one ADSL port.

     This is basically an IXDP425 with an IXP465 and 32M of flash instead
     of just 16.
