Anyone affected by this might want to take a look at bug 1776189 where
Ubuntu added a special machine type to more easily set "host-phys-bits"
which is the qemu flag to have more (usually the host has more)

spapr_create_pci_child_dt() is a trivial wrapper around
spapr_populate_pci_child_dt(), but is the latter's only caller. So fold
them together into spapr_dt_pci_device(), which closer matches our modern
naming convention.
While there, make a number of cleanups to the function itself. This is

spapr_populate_pci_child_dt() adds a 'name' property to the device tree
node for PCI devices. This is never necessary for a flattened device tree,
it is implicit in the name added when the node is constructed. In fact
anything we do add to a 'name' property will be overwritten with something

A P2P bridge will attempt to handle the hotplug with SHPC, which doesn't
work in the PAPR environment. Instead we want to direct all PCI hotplug
actions to the PAPR specific host bridge which will use the PAPR hotplug

DRC ids are more or less arbitrary, as long as they're consistent. For

Using bus number is broken, however, because it can change if the guest

The pseries machine type already allows PCI hotplug and unplug via the

this to allow PCI to PCI bridges to be hotplugged, and devices to be

Device nodes for PCI bridges (both host and P2P) describe both the bridge

For user-only, we require only the random number bits of the
crypto subsystem. Rename crypto-aes-obj-y to crypto-user-obj-y,
and add the random number objects, plus init.o to handle any
extra stuff the crypto library requires.
Move the crypto libraries from libs_softmmu and libs_tools to
LIBS, so
Avoids leaking the /dev/urandom fd into any child processes.
