[PATCH][RESEND v5 0/3] Hyper-V Dynamic Memory Protocol driver (hv-balloon 🎈️)

[Maciej S. Szmigiero]

From: "Maciej S. Szmigiero" <maciej.szmigiero@oracle.com>

This is almost a pure rebase/resend of the v4 of patch series located here:
https://lore.kernel.org/qemu-devel/cover.1682584770.git.maciej.szmigiero@oracle.com/

The only other change from the previous version is that the check for the
required Glib's GTree operations was moved from the configure script to the
meson build script in keeping with the spirit of the times (and the driver
was re-tested too).
