I think the xdindirect is coming from qemu's hw/virtio/virtio.h

Define 'virtio_pci_cap64' to allow capabilities to describe
memory regions larger than, or with an offset larger than 4GiB.

Define the PCI capability used for enumerating shared memory regions.
Each capability contains a 'struct virtio_pci_cap64'
Multiple capabilities of this type may exist for a device and may
be distinguished using the 'cap.id' field.
From: "Dr. David Alan Gilbert"
The new virtio-shared memory region system allows multiple regions
to be defined for a device; each of these is the same type of
capability.
To allow multiple capabilities of the same type, create
an 'id' field to differentiate them.

It might be worth commenting that pair of functions to make it clear
why they are so different; I guess the kfree_page_bitmap
is used just before you free the structure above it so you
don't need to keep the count/pointers updated?

ing perhaps the qemu could just open /proc/self/pagemap
and check if the page was mapped; that would seem cheap if we're checking big
ranges; and that would find all the balloon pages.

to update it's bitmap; HPe's solution is to migrate it's balloon
bitmap along with the migration data.

I very rarely use all it's RAM, so it's got a big chunk of free RAM, and yes
it's got a big chunk of cache as well.

patch f942dc2552b8bfdee607be867b12a8971bb9cd85
It does look like that should be an unsigned (given it's assigned
0 and 1)
