Hmm, I've seen this problem before. See Russell's explanation here:

I don't believe it's a problem my end, but if it starts happening
regularly I'll investigate further.

I wonder what's happening here is that the mailing list is converting
your messages from quoted-printable to plain text.

Looking at two of your recent messages, one of them came via the mailing
list.  That one was not quoted-printable.  These ones which you Cc'd me
on, and arrived before the copy from the mailing list came through as
quoted-printable though.

You've hit the nail on the head. On leaving ARM the headers get munged to:

Content-Type: text/plain; charset=WINDOWS-1252
Content-Transfer-Encoding: quoted-printable
 
The mailing list fixes that up. See the headers on one of the LPAE patches
sent by Catalin:

https://patchwork.kernel.org/patch/502491/

AFAIK, git-send-email doesn't generate quoted-printable mails.  From what
I remember, it doesn't generate any MIME headers at all either, expecting
the first MTA to be able to figure out what to do with the following
string of bytes.  It's not surprising that some MTAs may do weird things
with that.

I don't use git send-email, but instead have my own scripts based around
git format-patch, and adds the following headers:

  MIME-Version: 1.0
  Content-Disposition: inline
  Content-Type: text/plain; charset="us-ascii"

Even if I make sure my headers match this, they still get reverted to the
stuff I mentioned earlier. If I specify Content-Transfer-Encoding: binary
then it gets left alone but I'm not sure if that's better or worse than
quoted-printable.
 

to each file it produces, as well as other header modifications.  I've
then got a separate script which sends the contents of the directory
slowly (20sec between each message) via '/usr/sbin/sendmail' (iow,
the local MTA - exim for me) to make it a little kinder on MTAs.

Oh for a local MTA... (ports are all blocked here).
