Invoking io_setup(MAX_EVENTS) we ask kernel to create ring buffer for us
with specified number of events.  But kernel ring buffer allocation logic
is a bit tricky (ring buffer is page size aligned + some percpu allocation
are required) so eventually more than requested events number is allocated.

From a userspace side we have to follow the convention and should not try
to io_submit() more or logic, which consumes completed events, should be
changed accordingly.  The pitfall is in the following sequence:

    MAX_EVENTS = 128
    io_setup(MAX_EVENTS)

    io_submit(MAX_EVENTS)
    io_submit(MAX_EVENTS)

    /* now 256 events are in-flight */

    io_getevents(MAX_EVENTS) = 128

    /* we can handle only 128 events at once, to be sure
     * that nothing is pended the io_getevents(MAX_EVENTS)
     * call must be invoked once more or hang will happen. */

To prevent the hang or reiteration of io_getevents() call this patch
restricts the number of in-flights, which is now limited to MAX_EVENTS.

Commit 86b50f2e ("Disable huge page support if it is not available
for main RAM") already made sure that huge page support is not announced
to the guest if the normal RAM of non-NUMA configurations is not backed
by a huge page filesystem. However, there is one more case that can go
wrong: NUMA is enabled, but the RAM of the NUMA nodes are not configured
with huge page support (and only the memory of a DIMM is configured with
it). When QEMU is started with the following command line for example,
the Linux guest currently crashes because it is trying to use huge pages
on a memory region that does not support huge pages:

 qemu-system-ppc64 -enable-kvm ... -m 1G,slots=4,maxmem=32G -object \
   memory-backend-file,policy=default,mem-path=/hugepages,size=1G,id=mem-mem1 \
   -device pc-dimm,id=dimm-mem1,memdev=mem-mem1 -smp 2 \
   -numa node,nodeid=0 -numa node,nodeid=1

To fix this issue, we've got to make sure to disable huge page support,
too, when there is a NUMA node that is not using a memory backend with
huge page support.

If CPU core addition or removal is allowed in random order leading to
holes in the core id range (and hence in the cpu_index range), migration
can fail as migration with holes in cpu_index range isn't yet handled
correctly.

Prevent this situation by enforcing the addition in contiguous order
and removal in LIFO order so that we never end up with holes in
cpu_index range.

This ioctl() call to VFIO_IOMMU_SPAPR_TCE_REMOVE was left over from an
earlier version of the code and has since been folded into
vfio_spapr_remove_window().

It wasn't caught because although the argument structure has been removed,
the libc function remove() means this didn't trigger a compile failure.
The ioctl() was also almost certain to fail silently and harmlessly with
the bogus argument, so this wasn't caught in testing.

If the host has 8 threads/core and the guest is started with:

-smp cores=1,threads=4,maxcpus=12

It is possible to crash QEMU by doing:

(qemu) device_add host-spapr-cpu-core,core-id=16,id=foo
(qemu) device_del foo
Segmentation fault

This happens because spapr_core_unplug() assumes cpu_dt_id == core_id.
As long as cpu_dt_id is derived from the non-table cpu_index, this is
only true when you plug cores with contiguous ids.

It is safer to be consistent: the DR connector was created with an
index that is immediately written to cc->core_id, and spapr_core_plug()
also relies on cc->core_id.

Let's use it also in spapr_core_unplug().

KVM adjusts the MPIDR of guest vcpus based on the architecture of
the host, 32-bit vs. 64-bit, and, for 64-bit, also on the type of
GIC the guest is using. To be consistent and improve SGI efficiency
we make the same adjustments for TCG as 64-bit KVM hosts. We neglect
to add consistency with 32-bit KVM hosts, as that would reduce SGI
efficiency and KVM is expected to change.

As MPIDR is a system register, and thus guest visible, we only make
adjustments for current and later versioned machines.

At the moment the following QEMU command line triggers an assertion
failure (minimal reproducer by Cole):

  qemu-system-aarch64 \
    -machine virt-2.6,accel=tcg \
    -nodefaults \
    -no-user-config \
    -nographic -monitor stdio \

    -drive file=foo.img,format=raw,if=none,id=d1 \
    -device scsi-hd,bus=scsi1.0,drive=d1

  qemu-system-aarch64: migration/savevm.c:615:
  vmstate_register_with_alias_id:
  Assertion `!se->compat || se->instance_id == 0' failed.

The reason is that the vmstate sections for the two scsi-hd devices are
not uniquely identifiable by name.

The direct parent buses of the scsi-hd devices -- scsi0.0 and scsi1.0 --
support the BusClass.get_dev_path member function. scsibus_get_dev_path()
formats a device path prefix with the help of its topologically parent
bus, and then appends the chan:id:lun triplet to it. For both scsi-hd
devices, this triplet is 0:0:0.

(Here we use "device path" in the QEMU migration sense, for vmstate
section identification, not in the OFW or UEFI device path senses.)

The virtio-scsi HBA is plugged into the virtio-mmio bus (implemented by
the internal VirtIOMMIOProxy device). This bus class
(TYPE_VIRTIO_MMIO_BUS) inherits, as its get_dev_path() member function,
the virtio_bus_get_dev_path() method from its parent class
(TYPE_VIRTIO_BUS).

virtio_bus_get_dev_path() does not format any kind of device address on
its own; "virtio addresses" are transport-specific. Therefore
virtio_bus_get_dev_path() asks the topologically parent bus of the proxy
object (implementing the specific virtio transport) to format the address
of the proxy object.

(For virtio-pci devices (where the proxy is an instance of VirtIOPCIProxy,
plugged into a PCI bus), this ends up in pcibus_get_dev_path().)

However, VirtIOMMIOProxy is usually (in practice: always) plugged into
"main-system-bus", the singleton TYPE_SYSTEM_BUS object. This BusClass
does not support formatting QEMU vmstate device paths at all (as
SysBusDevice objects can have zero or more IO ports and zero or more MMIO
regions). Hence the formatting request delegated from
virtio_bus_get_dev_path() gets answered with NULL.

The end result is that the two scsi-hd devices end up with the same device
path "0:0:0", which triggers the assert.

We can solve this by recognizing that virtio-mmio transports are
distinguished from each other by their base addresses in MMIO address
space. Implement virtio_mmio_bus_get_dev_path() as follows:

(1) The virtio device whose devpath is to be formatted resides on a
    virtio-mmio bus that is implemented by a VirtIOMMIOProxy object. Ask
    the parent bus of VirtIOMMIOProxy to format the device path of
    VirtIOMMIOProxy, as a path prefix. (This is identical to what
    virtio_bus_get_dev_path() does.)

(2) Append the base address of VirtIOMMIOProxy to the device path, such
    as:
    - virtio-mmio@000000000a003e00,
    - virtio-mmio@000000000a003c00.

Given that these device paths are placed in the migration stream, step (2)
above, if done unconditionally, would break migration. So make that step
conditional on a new VirtIOMMIOProxy property, which is enabled for 2.7
machine types and later.

FLASH chip on XTFPGA boards is connected with 16-bit-wide interface.
Latest U-Boot can see the difference and does not work correctly with
32-bit-wide interface.
Set FLASH chip 'width' property to 2.
