Introduce replay_discarded callback similar to our existing
replay_populated callback, to be used my migration code to never migrate
discarded memory.

Where is the virtio spec update for this?

Squash that into patch #2

No, please do that properly right from start.
Needs a uuid -> resource-id table or hash in qemu.
When Hexagon was added we forgot to add it to the QEMU_ARCH_*
enumeration. This doesn't cause a visible effect because at the
moment Hexagon is linux-user only and the QEMU_ARCH_* constants are
only used in softmmu, but we might as well add it in, since it's the
only architecture currently
Instead of using an ifdef ladder in arch_init.c (which we then have
to manually update every time we add or remove a target
architecture), have meson.build put "#define QEMU_ARCH QEMU_ARCH_FOO"
in the config-target.h file.

Currently, when someone (i.e., the VM) accesses discarded parts inside a
RAMBlock with a RamDiscardManager managing the corresponding mapped memory
region, postcopy will request migration of the corresponding page from the
source. The source, however, will never answer, because it refuses to

I guess having a runtime switch for that would be a good idea, and
probably have default it off while the API is unstable still.

You leak the region instead of properly

Commit messages should describe what the patch is doing and why,

arch_init.h only defines the QEMU_ARCH_* enumeration and the
arch_type global. Don't include it in files that don't use those.

We added a stub for the arch_type global in commit 5964ed56d9a1 so
that we could compile blockdev.c into the tools. However, in commit
9db1d3a2be9bf we removed the only use of arch_type from blockdev.c.
The stub is therefore no longer needed, and we can delete it again,

The parameter is unused, let's drop it.

We don't want to migrate memory that corresponds to discarded ranges as
managed by a RamDiscardManager responsible for the mapped memory region of
the RAMBlock. The content of these pages is essentially stale and
without any guarantees for the VM ("logically unplugged").
