Wow, I didn't know optional sections existed.  We could have used it for
hw/char/parallel.c, but that was added only a couple months before
optional sections.

Queued for 2.8.

I'd forgotten that they existed and was about to write them to
solve this problem, and then found the code I apparently reviewed
a year or so ago :-)

[Qemu-devel] [PATCH 0/2] pcspk migration compatibility

2016-11-28 Thread Dr. David Alan Gilbert (git)
From: "Dr. David Alan Gilbert" 

Hi,
  39c88f56 added VMState for pcspk but turned it on for
all machine types, this breaks backwards compatibility
to older machine types.

  If this is too late for 2.8 then I suggest we take the 1st
of these two patches, which just makes it a property to flip
for those of us who need it.  Adding the 2nd patch after 2.8
might cause problems for people using 2.8 with 2.7 machine
type.
