isa-bus: Remove bogus IRQ sharing check
Nothing prevented IRQ sharing on the ISA bus in principle. Not allboards supported this, neither each and every card nor driver and OS.Still, there existed valid IRQ sharing scenarios, (at least) two of themcan also be found in QEMU: >2 PC UARTs and the PREP IDE buses....
piix: tag as not hotpluggable.
This patch tags all pci devices which belong to the piix3/4 chipsets asnot hotpluggable (Host bridge, ISA bridge, IDE controller, ACPI bridge).

ide: Register vm change state handler once only
We register the vm change state handler in a PCI BAR map() function.This function can be called multiple times throughout the lifetime of aPCI IDE device. This results in duplicate vm change state handlers...
ide: Split out BMDMA code from ATA core
The ATA core is currently heavily intertwined with BMDMA code. Let's loosenthat a bit, so we can happily replace the DMA backend with differentimplementations.

pci: don't overwrite multi functio bit in pci header type.
Don't overwrite pci header type.Otherwise, multi function bit which pci_init_header_type() setsappropriately is lost.Anyway PCI_HEADER_TYPE_NORMAL is zero, so it is unnecessary to zerowhich is already zero cleared....
savevm: Add DeviceState param
When available, we'd like to be able to access the DeviceStatewhen registering a savevm. For buses with a get_dev_path()function, this will allow us to create more unique savevmid strings.

cmd646: pass pci_dev as it needs it
Instead of doing tricks to get the pci_dev, just pass it in the 1stplace. Patch is a bit longer that reverting the pci_dev field, but itstates more clearly (IMHO) what we are doing.
It also fixes the bm test, now that you told me that ->unit is not...
piix: symbolic constants
No functional changes. I verified that the generated binarydoes not change.

workaround for cmd646 bmdma register access while no dma is active
This is a workaround only, and is a partial revertof a few changes to BMDMAState which removed pci_devfield on the way.
- cmd646 pci_from_bm() expects bm->unit value tocorrespond with bm data being passed to callback...
qdev: Replace device names containing whitespace
Device names with whitespace require quoting in the shell and in themonitor. Some of the offenders are also overly long. Some have amore convenient alias, some don't.
The place for verbose device names is DeviceInfo member desc. The...
pci: introduce pcibus_t to represent pci bus address/size instead of uint32_t
This patch is preliminary for 64 bit BAR support.Introduce dedicated type, pcibus_t, to represent pci bus address/sizeinstead of uint32_t.Later this type will be changed to uint64_t....

There is absolutely no need to call reset functions when initializingdevices. Since we are already registering them, calling qemu_system_reset()should suffice. Actually, it is what happens when we reboot the machine,...
