This patch is *huge*, more than 800kB. It keeps being stuck in the the
filter of the qemu-s390x list each time you send it. Please:

1) Try to break it up in more digestible pieces, e.g. change only one
subsystem at a time (this is also better reviewable by people who are
interested in one area)

2) Do not send HTML emails to the mailing list.

 Thanks,
  Thomas

This is not really possible, since the patch is basically a
search-and-replace.  You could perhaps use some magic
("DEVICE_MEMOP_ENDIAN" or something like that) to allow a split, but it
would introduce more complication than anything else.

Agreed on the HTML though. :)

I'm stupid, at this point of the series it _would_ be possible to split
the patch by subsystem.  Still not sure it would be actually an advantage.

It might be easier to review if we split by symbol, one rename per patch over
the entire code base.
