bde299a247 Revert "pci: add some stubs"
This reverts commit 0883c5159f.

Those stubs were only used by PCI ESP emulation, which is now
not compiled on architectures which have no PCI bus support.

26b9b5fe17 virtio: fix vhost handling
Commit b1f416aa8d breaks vhost_net
because it always registers the virtio_pci_host_notifier_read() handler
function on the ioeventfd, even when vhost_net.ko is using the ioeventfd.
The result is both QEMU and vhost_net.ko polling on the same eventfd
and the virtio_net.ko guest driver seeing inconsistent results:

  # ifconfig eth0 192.168.0.1 netmask 255.255.255.0
  virtio_net virtio0: output:id 0 is not a head!

To fix this, proceed the same as we do for irqfd: add a parameter to
virtio_queue_set_host_notifier_fd_handler and in that case only set
the notifier, not the handler.

ee785fed5d Fixes related to processing of qemu's -numa option
The -numa option to qemu is used to create [fake] numa nodes
and expose them to the guest OS instance.

There are a couple of issues with the -numa option:

a) Max VCPU's that can be specified for a guest while using
   the qemu's -numa option is 64. Due to a typecasting issue
   when the number of VCPUs is > 32 the VCPUs don't show up
   under the specified [fake] numa nodes.

b) KVM currently has support for 160VCPUs per guest. The
   qemu's -numa option has only support for upto 64VCPUs
   per guest.
This patch addresses these two issues.

Below are examples of (a) and (b)

a) >32 VCPUs are specified with the -numa option:

/usr/local/bin/qemu-system-x86_64 \
-enable-kvm \
71:01:01 \

76b523db00 megasas: static SAS addresses
This patch introduces a new property 'sas_address' which
allows the user to specify the SAS address for the HBA.
The default address is following the NAA locally assigned
identifier format with the locally assigned address
0x525400 as used eg for the MAC addresses.
The lower bytes are set to the pci address which
will ensure uniqueness for the local machine.

The port addresses are now calculated based on the magic
number 0x1221 (which is found in real hardware, too) plus
the device number.

c8057f951d Support 'help' as a synonym for '?' in command line options
For command line options which permit '?' meaning 'please list the
permitted values', add support for 'help' as a synonym, by abstracting
the check out into a helper function.

This change means that in some cases where we were being lazy in
our string parsing, "?junk" will now be rejected as an invalid option
rather than being (undocumentedly) treated the same way as "?".

Update the documentation to use 'help' rather than '?', since '?'
is a shell metacharacter and thus prone to fail confusingly if there
is a single character filename in the current working directory and
the '?' has not been escaped. It's therefore better to steer users
towards 'help', though '?' is retained for backwards compatibility.

We do not, however, update the output of the system emulator's -help
(or any documentation autogenerated from the qemu-options.hx which
is the source of the -help text) because libvirt parses our -help
output and will break. At a later date when QEMU provides a better
interface so libvirt can avoid having to do this, we can update the
-help text too.

Moving reset callback into cpu object from board level and
resetting cpu at the end of x86_cpu_realize() will allow properly
create cpu object during run-time (hotplug) without calling reset externaly.

When reset over QOM hierarchy is implemented, reset callback
should be removed.

v2:
  - leave cpu_reset in pc_new_cpu() for now, it's to be cleaned up when APIC
    init is moved in cpu.c

dd673288a8 target-i386: move cpu halted decision into x86_cpu_reset
MP initialization protocol differs between cpu families, and for P6 and
onward models it is up to CPU to decide if it will be BSP using this
protocol, so try to model this. However there is no point in implementing
MP initialization protocol in qemu. Thus first CPU is always marked as BSP.

This patch:
 - moves decision to designate BSP from board into cpu, making cpu
self-sufficient in this regard. Later it will allow to cleanup hw/pc.c
and remove cpu_reset and wrappers from there.
 - stores flag that CPU is BSP in IA32_APIC_BASE to model behavior
described in Inted SDM vol 3a part 1 chapter 8.4.1
 - uses MSR_IA32_APICBASE_BSP flag in apic_base for checking if cpu is BSP

patch is based on Jan Kiszka's proposal:

0ed8b6f67f Avoid returning void
It's silly and non-conforming to standards to return void,
don't do it.

16fd921bd3 hw/escc: Drop duplicate definition of 'disabled' property
Drop a duplicate definition of the 'disabled' property from
the escc qdev property list: this redefinition is currently
effectively ignored but will become an error. (The duplication
was inadvertently introduced in 2009 in commit ec02f7dec2.)

4c205d0cb1 virtio-scsi: enable MSI-X support
While virtio-scsi does support multiqueue, the default number of
interrupt vectors is not enough to actually enable usage of
multiple queues in the driver; this is because with only 2
vectors the driver will not be able to use a separate
interrupt for each request queue.  Derive the desired number
of vectors from the number of request queues.

3f910904ec virtio-scsi: add ioeventfd support
Probably due to bad merge months ago, virtio-scsi-pci did not have
ioeventfd support.  Fix this and enable it by default, as is the
case for other virtio-pci devices.
