Hi Jim,
There are a couple of CI failures after this, one on 32-bit and
one with CLang
Yep, received mail from gitlab as well. Will take a look...

V4 series adding support for QEMU's mapped-ram stream format [1] and
migration capability. The use of mapped-ram is controlled by extending
save_image_format setting in qemu.conf with a new 'sparse' option. The
'raw' format continues to be the default.
Also included are patches that leverage mapped-ram to add support for
parallel save/restore.
Changes in V4:
* Rebased on latest master, including the series
"qemu: Support specifying save image format"
