pcnet-pci: Fix PIO word access to PROM

Implement the various IO access widths according to the spec. This
specifically unbreaks word and dword access to the PROM area that is
mapped into IO space. It also drops redundant upper limit checks and
spurious "return void"....

usb-ehci: Use PCI DMA stub functions

This updates the usb-ehci device emulation to use the explicit PCI DMA
wrapper to initialize its scatter/gathjer structure. This means this
driver should not need further changes when the sglist interface is
extended to support IOMMUs....

virtio: Add PCI memory BAR in addition to PIO BAR

Currently, virtio devices are usually presented to the guest as an
emulated PCI device, virtio_pci. Although the actual IO operations
are done through system memory, the configuration of the virtio device...

Move filedescriptor parsing code from net.c into qemu_parse_fd()

Move the parsing of a filedescriptor into a common function
qemu_parse_fd() so others can use it as well. Have net.c call this
function.

Add stub functions for PCI device models to do PCI DMA

This patch adds functions to pci.[ch] to perform PCI DMA operations.
At present, these are just stubs which perform directly cpu physical

checkpatch: remove rule on non-indented labels

There are 508 non-indented (non-default) labels, and 511 that are
indented. So the rule is debatable at least. Actually, in the
common case of labels at the outermost scope, there is really just
one place where to put the label, so the rule is just wrong IMHO....

ps2: migrate ledstate

Make the ps2 device track its ledstate so that we can migrate it.
Otherwise it gets lost across migration, and spice-server gets

Use dma_addr_t type for scatter/gather code

This patch uses the newly created dma_addr_t type throughout the
scatter/gather handling code in dma-helpers.c whenever we need to

qxl: create slots on post_load in vga state

RHBZ 740547
