No need for xen_vcpu_init anymore:
- the RTC emulator doesn't have any periodic timers continuously running
even in absence of guest interactions anymore;
- qemu_dummy_start_vcpu takes care of disabling TCG for us, so we don't
need to do it manually here.

We are currently setting the PCI hole to start at HVM_BELOW_4G_RAM_END,
that is 0xf0000000.
Start the PCI hole at 0xe0000000 instead, that is the same value used by
pc_init1 and qemu-xen-traditional.

This fixes a regression introduced by:
commit 62fc403f11523169eb4264de31279745f48e3ecc
Author: Igor Mammedov <imammedo@redhat.com>
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.

Sun4c and Sun4d architectures and related CPUs are not fully implemented
(especially Sun4c MMU) and there has been no interest for them.
Likewise, a few CPUs (Cypress, Ross etc) are only half implemented.
Remove the machines and CPUs, they can be re-added if needed later.

"Readable" is a very unfortunate name for this flag because even a
rom_device region will always be readable from the guest POV. What
differs is the mapping, just like the comments had to explain already.
Also, readable could currently be understood as being a generic region
flag, but it only applies to rom_device regions.
So rename the flag and the function to modify it after the original term
"ROMD" which could also be interpreted as "ROM direct", i.e. ROM mode
with direct access. In any case, the scope of the flag is clearer now.

Net queues support efficient "receive disable". For example, tap's file
descriptor will not be polled while its peer has receive disabled. This
saves CPU cycles for needlessly copying and then dropping packets which
the peer cannot receive.
rtl8139 is missing the qemu_flush_queued_packets() call that wakes the
queue up when receive becomes possible again.
As a result, the Windows 7 guest driver reaches a state where the
rtl8139 cannot receive packets. The driver has actually refilled the
receive buffer but we never resume reception.
The bug can be reproduced by running a large FTP 'get' inside a Windows
7 guest:
$ qemu -netdev tap,id=tap0,...
-device rtl8139,netdev=tap0
The Linux guest driver does not trigger the bug, probably due to a
different buffer management strategy.

Although we try our best to automatically detect broken versions
of Linux which assume the old broken IRQ mapping we used to implement
for our model of the Versatile PCI controller, it turns out that
some particularly new kernels manage to outwit the autodetection.
We therefore provide a property for enabling the old broken IRQ
mapping, so that if users happen to have such a kernel they can
work around its deficiencies with the command line option:
-global versatile_pci.broken-irq-mapping=1

Newer versatilepb kernels still don't get the IRQ mapping right
for the PCI controller, but they get it differently wrong (they add
a fixed +64 offset to everything they write to PCI_INTERRUPT_LINE).

detailed comment on the various different behaviours that might
be present.

This reverts commit 5f37ef92b7690423ac6311d3c597e182fc5f8fe6.
It turns out that some kernels incorrectly depend on the
old QEMU behaviour of not putting the host PCI bridge device
where the hardware puts it, because they use a swizzling IRQ
mapping which is incorrect but happens to match up with old
broken QEMU when the slot number mod 4 is zero. Since we
start PCI devices at 11, if we put the host bridge at 29
then the first real PCI device goes at 11 and doesn't work.
Not putting the host bridge at 29 means it defaults to 11,
so the first real PCI device is at 12 and works.
Since continuing with the old behaviour doesn't cause problems
for kernels which do work with hardware, the simplest fix for
this is to revert the change.

While Markus's analysis is entirely correct, there are 1.6 patches
that fix the bug for real and without requiring machine type hacks.
Let's think of the children who will have to read this code, and
avoid a complicated mess of semantics that differ between <1.5,
1.5, and >1.5.

With a SPICE_DISPLAY_CAP_MONITORS_CONFIG capable client, the client needs to
know what part of the primary to use for each monitor. If the guest driver
does not support this, the server sends messages to the client for a
single monitor spanning the entire primary.
As soon as the guest calls spice_qxl_monitors_config_async once, the server
sets the red_worker driver_has_monitors_config flag and stops doing this.
This is a problem when the driver gets unloaded, for example after a reboot
or when switching to a text vc with usermode mode-setting under Linux.
To reproduce this start a multi-mon capable Linux guest which uses
usermode mode-setting and then once X has started switch to a text vc. Note
how the client window does not only not resize, if you try to resize it
manually you always keep blackborders since the aspect is wrong.
This patch calls a new spice-server method called spice_qxl_driver_unload
which clears the driver_has_monitors_config flag inside the server, thereby
fixing this.

The device is supposed to reset the Bus Master IDE Active bit in the
status register when 0 is written to the Start/Stop Bus Master bit in
the command register.
In the common cases this happens automatically because bdrv_drain_all()

There are several several issues in the current checking:
- The check was based on the minus of unsigned values which can overflow
- It was done after .{set|get}_config() which can lead crash when config_len
is zero since vdev->config is NULL
Fix this by:
- Validate the address in virtio_pci_config_{read|write}() before
.{set|get}_config
- Use addition instead minus to do the validation

Due to various unfortunate reasons we cannot reliable detect a guest
cancelling a packet as soon as it happens, instead we detect cancels
with some delay.
When packets are handled async, and we directly pass the guest memory for
the packet to the usb-device as iovec, this means that the usb-device can
write to guest-memory which the guest has already re-used for other purposes
-> not good!
This patch fixes this by adding an intermediate buffer and writing back not
only the result, but also the data, of async completed packets when scanning
the schedule.

Alloes to pass through usb2 devices on usb1 host controllers if possible.
Brings the libusb implementation to feature-parity with the linux usbfs
code, so the usb-host implementation in 1.5 (libusb) doesn't regress
compared to 1.4 (usbfs).

Commit 32993698 (vhost: disable on tap link down) tries to disable the vhost
also when the peer's link is down. But the check was not done properly, the
vhost were only started when:
1) peer's link is not down
2) virtio-net has already been started.
Since == have a higher precedence than &&, place a brace to make sure both the
conditions were met then does the check. This fixes the crash when doing a savem
after set the link off which let qemu crash and complains:
virtio_net_save: Assertion `!n->vhost_started' failed.

The Atom core (cpu name "n270" in QEMU speak) supports MOVBE. This is
needed when booting 3.8 and later linux kernels built with the MATOM
target because we require MOVBE in order to boot properly now.

Necessary since memory region accessor assumes read and write
methods are registered. Otherwise reading I/O port 0x7e segfaults.

If no kernel IPL entry is specified, boot the bios and pass if available

The provided information will be used in the next commit from the BIOS.
