f51074cdc6 pci-hotplug-old: Has been dead for five major releases, bury
Commit 79ca616 (v1.6.0) accidentally disabled legacy x86-only HMP
commands pci_add, pci_del: it defined CONFIG_PCI_HOTPLUG only as make
variable, not as preprocessor macro, killing the code conditional on
defined(CONFIG_PCI_HOTPLUG_OLD).

In all this time, nobody reported the loss.  I only noticed it when I
tried to test some error reporting change that forced me to touch this
old crap again.

Fun: git-log hw/pci/pci-hotplug-old.c shows our faith in the backward
compatibility god has been strong enough to sacrifice at its altar
about a dozen times, but not strong enough to even once verify the
legacy feature's still there, let alone works.

Remove the commands along with the code backing them.

8af738b3ee Give ivshmem its own config option
Currently the ivshmem device is built whenever both PCI and KVM support are
included.  This patch gives it its own config option to allow easier
customization of whether to include it.  It's enabled by default in the
same circumstances as now - when both PCI and KVM are available.

2296594257 Create specific config option for "platform-bus"
Currently the "platform-bus" device is included for all softmmu builds.
This bridge is intended for use on any platforms that require dynamic
creation of sysbus devices.  However, at present it is used only for the
PPC E500 target, with plans for the ARM "virt" target in the immediate
future.

To avoid a not-very-useful entry appearing in "qemu -device ?" output on
other targets, this patch makes a specific config option for platform-bus
and enables it (for now) only on ppc configurations which include E500
and on ARM (which always includes the "virt" target).

4681867544 Add specific config options for PCI-E bridges
The i82801b11, ioh3420 and xio3130 PCI Express devices are currently
included in the build unconditionally.

While they could theoretically appear on any target platform with PCI-E,
they're pretty unlikely to appear on platforms that aren't Intel derived.

Therefore, to avoid presenting unlikely-to-be-relevant devices to the user,
add config options to enable these components, and enable them by default
only on x86 and arm platforms.

(Note that this patch does include these for aarch64, via its inclusion of
arm-softmmu.mak).

c3cf77cb63 Make sysbus EHCI devices ARM only by default
A number of ARM embedded boards include EHCI USB host controllers which
appear as directly mapped devices, rather than sitting on a PCI bus.

At present code to emulate such devices is included whenever EHCI support
is included.  This patch adjusts teh config options to only include them
in builds targetting ARM by default.

10b7e74bf2 pc: implement pc-dimm device abstraction
Each hotplug-able memory slot is a PCDIMMDevice.
A hot-add operation for a memory device:
- creates a new PCDIMMDevice and makes hotplug controller to map it into
  guest address space

Hotplug operations are done through normal device_add commands.
For migration case, all hotplugged memory devices on source should be
specified on target's command line using '-device' option with
properties set to the same values as on source.

To simplify review, patch introduces only PCDIMMDevice QOM skeleton that
will be extended by following patches to implement actual memory hotplug
and related functions.

DIGIC chips. All information about DIGIC chip
internals is based on reverse engineering efforts

b86160555f integrator: fix Linux boot failure by emulating dbg region
Commit 9b8c69243 (since reverted) broke the ability to boot the kernel
as the value returned by unassigned_mem_read returned non-zero and left
the kernel looping forever waiting for it to change (see
integrator_led_set in the kernel code).

Relying on a varying implementation detail is incorrect anyway so this
introduces a basic stub of a memory region for the debug/LED section
on the integrator board.

11ad93f681 xics-kvm: Support for in-kernel XICS interrupt controller
Recent (host) kernels support emulating the PAPR defined "XICS" interrupt
controller system within KVM.  This patch allows qemu to initialize and
configure the in-kernel XICS, and keep its state in sync with qemu's XICS
state as necessary.

This should give considerable performance improvements.  e.g. on a simple
IPI ping-pong test between hardware threads, using qemu XICS gives us
around 5,000 irqs/second, whereas the in-kernel XICS gives us around
70,000 irqs/s on the same hardware configuration.

66aae5e1ec default-configs: Fix A9MP and A15MP config names
When individual CONFIG_ switches for the A9MPcore and A15MPcore
devices were created, they were inadvertently given incorrect names
(CONFIG_ARM9MPCORE and CONFIG_ARM15MPCORE). These CPUs are
"Cortex-A9MP" and "Cortex-A15MP", and in particular the ARM9 is
a different (rather older) CPU than the Cortex-A9. Rename the
CONFIG_ switches to bring them into line with the source file
names and CPU names.

cc413a3935 mips_malta: do not raise exceptions when accessing invalid memory
Since commit c658b94f6e, MIPS raises
exceptions when accessing invalid memory. This is not the correct
behaviour for MIPS Malta Core LV, as the GT-64120A system controller
just ignore undecoded access. This feature is used by the Linux kernel
to probe for some devices.

Emulate the correct behaviour in QEMU by adding an empty slot covering
the entire memory space decoded by the GT-64120A.

79ca616f29 pci: Cleanup configuration for pci-hotplug.c
pci-hotplug.c and the CONFIG_PCI_HOTPLUG variable which controls its
compilation are misnamed.  They're not about PCI hotplug in general, but
rather about the pci_add/pci_del interface which are now deprecated in
favour of the more general device_add/device_del interface.  This patch
therefore renames them to pci-hotplug-old.c and CONFIG_PCI_HOTPLUG_OLD.

CONFIG_PCI_HOTPLUG=y was listed twice in {i386,x86_64}-softmmu.make for no
particular reason, so we clean that up too.  In addition it was included in
ppc64-softmmu.mak for which the old hotplug interface was never used and is
unsuitable, so we remove that too.

Most of pci-hotplug.c was additionaly protected by #ifdef TARGET_I386.  The
small piece which wasn't is only called from the pci_add and pci_del hooks
in hmp-commands.hx, which themselves were protected by #ifdef TARGET_I386.
This patch therefore also removes the #ifdef from pci-hotplug-old.c,
and changes the ifdefs in hmp-commands.hx to use CONFIG_PCI_HOTPLUG_OLD.

d85937e683 kvm/openpic: in-kernel mpic support
Enables support for the in-kernel MPIC that thas been merged into the
KVM next branch.  This includes irqfd/KVM_IRQ_LINE support from Alex
Graf (along with some other improvements).

Note from Alex regarding kvm_irqchip_create():

  On x86, one would call kvm_irqchip_create() to initialize an
  in-kernel interrupt controller.  That function then goes ahead and
  initializes global capability variables as well as the default irq
  routing table.

  On ppc, we can't call kvm_irqchip_create() because we can have
  different types of interrupt controllers.  So we want to do all the
  things that function would do for us in the in-kernel device init
  handler.
