The overhead from three levels is an extra table, which is negligible.

This patch sorts out invalid use of pcibus_t.
In pci_register_bar(), pcibus_t wmask is used.
It should, However, be uint64_t because it is used to set
pci configuration space value(PCIDevice::wmask) by pci_set_quad()
or pci_set_long().
So make its type uint64_t and cast from pcibus_t to int64_t wh
Make type uint8_t from int because PCIIORegion::type is uint8_t.

qemu-config.c doesn't contain any target-specific code, and the
TARGET_I386 conditional code didn't get compiled as a result. Removing

Currently virtio-serial supports a maximum of 31 ports. Specifying the

Ensure we initialise virtio-serial only if max_ports is within the

These are a few fixes which I've submitted that are included in master

Dropping to 128K tables would reduce it to 16TB and 64k tables would
be 4TB.
