pci: Add root bus parameter to pci_nic_init()

At present, pci_nic_init() and pci_nic_init_nofail() assume that they will
only create a NIC under the primary PCI root. As we add support for
multiple PCI roots, that may no longer be the case. This patch adds a root...

pci: Abolish pci_find_root_bus()

pci_find_root_bus() takes a domain parameter. Currently PCI root buses
with domain other than 0 can't be created, so this is more or less a long
winded way of retrieving the main PCI root bus. Numbered domains don't
actually properly cover the (non x86) possibilities for multiple PCI root...

pc: pass PCI hole ranges to Guests

Guest currently has to jump through lots of hoops to guess the PCI hole
ranges. It's fragile, and makes us change BIOS each time we add a new
chipset. Let's report the window in a ROM file, to make BIOS do exactly
what QEMU intends....

pc_piix: cleanup init compat handling

Make sure 1.4 calls 1.5, 1.3 calls 1.4 etc.
This way it's enough to add enough new compat hook
in a single place in piix.

kvmclock: clock should count only if vm is running

kvmclock should not count while vm is paused, because:

1) if the vm is paused for long periods, timekeeping
math can overflow while converting the (large) clocksource
delta to nanoseconds.

2) Users rely on CLOCK_MONOTONIC to count run time, that is,...

pci-assign: remove the duplicate function name in debug message

KVM: PIC: Only commit irq routing when necessary

The current logic updates KVM's view of our interrupt map every time we
change it. While this is nice and bullet proof, it slows things down
badly for me. QEMU spends about 3 seconds on every start telling KVM what...

multiboot: Calculate upper_mem in the ROM

The upper_mem field of the Multiboot information struct doesn't really
contain the RAM size - 1 MB like we used to calculate it, but only the
memory from 1 MB up to the first (upper) memory hole.

In order to correctly retrieve this information, the multiboot ROM now...

cpu: Change cpu_exit() argument to CPUState

It no longer depends on CPUArchState, so move it to qom/cpu.c.

Prepares for changing GDBState::c_cpu to CPUState.
