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
bus parameter to pci_nic_init() (and updates callers accordingly) to allow
the machine init code using it to specify the right PCI root for NICs
created by old-style -net nic parameters. NICs created new-style, with
-device can of course be put anywhere.

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
buses, so this patch for now enforces the domain == 0 restriction in other
places to replace pci_find_root_bus() with an explicit
pci_find_primary_bus().

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,
time which OS has been in a runnable state (see CLOCK_BOOTTIME).
Change kvmclock driver so as to save clock value when vm transitions
from runnable to stopped state, and to restore clock value from stopped
to runnable transition.

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
news it has on its routing maps.
Instead, let's just synchronize the whole irq routing map as a whole when
we're done constructing it. For things that change during runtime, we can
still update the routing table on demand.

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
looks at the mmap it creates anyway and tries to find the size of
contiguous usable memory from 1 MB.
Drop the multiboot.c definition of lower_mem and upper_mem because both
are queried at runtime now.

Option -no-fd-bootchk asks the BIOS to attempt booting from a floppy
even when the boot sector signature isn't there, by setting a bit in
RTC CMOS. It was added back in 2006 (commit 52ca8d6a).
Two years later, commit 0ecdffbb added monitor command boot_set.
Implemented by new function pc_boot_set(). It unconditionally clears
the floppy signature bit in CMOS.
Commit e0f084bf added -boot option once to automatically change the
boot order on first reset. Reuses pc_boot_set(), thus also clears the
floppy signature bit. Commit d9346e81 took care to preserve this
behavior.
Thus, -no-fd-bootchk applies to any number of boots. Except it
applies just to the first boot with -boot once, and never after
boot_set. Weird. Make it stick instead: set the bit according to
-no-fd-bootchk in pc_boot_set().

Date: Mon Apr 29 18:54:13 2013 +0200
target-i386: Attach ICC bus to CPU on its creation
X86CPU should have parent bus so it could provide bus for child APIC.
The commit makes it mandatory to pass a valid ICC bus to cpu_x86_create,
but cpu_x86_init just passes NULL to it.
xen_machine_pv uses cpu_x86_init, therefore it has been broken.
This patch fixes the problem by removing the dummy CPU creation
altogether from xen_init_pv, relying on the fact that QEMU can now cope
with a machine without an emulated CPU.
