A subsequent patch to add support for setting linkspeed/duplex in
virtio-net, requires a few definitions from ethtool.h, which ends up
pulling in kernel.h and sysinfo.h as well.

  virtio-net: add linkspeed and duplex settings to virtio-net

Although linkspeed and duplex can be set in a linux guest via 'ethtool -s',
this requires custom ethtool commands for virtio-net by default.

Introduce a new feature flag, VIRTIO_NET_F_SPEED_DUPLEX, which allows
the hypervisor to export a linkspeed and duplex setting. The user can
subsequently overwrite it later if desired via: 'ethtool -s'.

Linkspeed and duplex settings can be set as:
'-device virtio-net,speed=10000,duplex=full'

where speed is [0...INT_MAX], and duplex is ["half"|"full"].

init_fadt_data() that will set common for pc/q35 values in
AcpiFadtData structure and acpi_get_pm_info() will complement
it with pc/q35 specific values initialization.

That will allow to get rid of fadt_setup() and generalize
build_fadt() so it could be easily extended for rev5 and
reused by ARM target.

While at it also move facs/dsdt/xdsdt offsets from build_fadt()
arg list into AcpiFadtData, as they belong to the same dataset.

Also it allows easily extending FADT to support other

It may need to treat PC-DIMM and NVDIMM differently, e.g., when
deciding the necessity of non-volatile flag bit in SRAT memory
affinity structures.

A new field 'nvdimm' is added to the union type MemoryDeviceInfo for
such purpose. Its type is currently PCDIMMDeviceInfo and will be
updated when necessary in the future.

It also fixes "info memory-devices"/query-memory-devices which
currently show nvdimm devices as dimm devices since
object_dynamic_cast(obj, TYPE_PC_DIMM) happily cast nvdimm to
TYPE_PC_DIMM which it's been inherited from.

  hw/acpi-build: build SRAT memory affinity structures for DIMM devices

ACPI 6.2A Table 5-129 "SPA Range Structure" requires the proximity
domain of a NVDIMM SPA range must match with corresponding entry in
SRAT table.

The address ranges of vNVDIMM in QEMU are allocated from the
hot-pluggable address space, which is entirely covered by one SRAT
memory affinity structure. However, users can set the vNVDIMM
proximity domain in NFIT SPA range structure by the 'node' property of
'-device nvdimm' to a value different than the one in the above SRAT
memory affinity structure.

In order to solve such proximity domain mismatch, this patch builds
one SRAT memory affinity structure for each DIMM device present at
boot time, including both PC-DIMM and NVDIMM, with the proximity
domain specified in '-device pc-dimm' or '-device nvdimm'.

The remaining hot-pluggable address space is covered by one or multiple
SRAT memory affinity structures with the proximity domain of the last
node as before.

  tests/bios-tables-test: add test cases for DIMM proximity

QEMU now builds one SRAT memory affinity structure for each PC-DIMM
and NVDIMM device presented at boot time with the proximity domain
specified in the device option 'node', rather than only one SRAT
memory affinity structure covering the entire hotpluggable address
space with the proximity domain of the last node.

Add test cases on PC and Q35 machines with 4 proximity domains, and
one PC-DIMM and one NVDIMM attached to the 2nd and 3rd proximity
domains respectively. Check whether the QEMU-built SRAT tables match
with the expected ones.

The following ACPI tables need to be added for this test:
  tests/acpi-test-data/pc/APIC.dimmpxm
  tests/acpi-test-data/pc/DSDT.dimmpxm
  tests/acpi-test-data/pc/NFIT.dimmpxm

  tests/acpi-test-data/q35/SSDT.dimmpxm
New APIC and DSDT are needed because of the multiple processors
configuration. New NFIT and SSDT are needed because of NVDIMM.

  migrate: Update ram_block_discard_range for shared

The choice of call to discard a block is getting more complicated
for other cases.   We use fallocate PUNCH_HOLE in any file cases;
it works for both hugepage and for tmpfs.
We use the DONTNEED for non-hugepage cases either where they're
anonymous or where they're private.

Care should be taken when trying other backing files.

  vhost+postcopy: Send address back to qemu

We need a better way, but at the moment we need the address of the
mappings sent back to qemu so it can interpret the messages on the
userfaultfd it reads.

This is done as a 3 stage set:
   QEMU -> client
      set_mem_table

   mmap stuff, get addresses

   client -> qemu
       here are the addresses

   qemu -> client
       OK - now you can use them

That ensures that qemu has registered the new addresses in it's
userfault code before the client starts accessing them.

Note: We don't ask for the default 'ack' reply since we've got our own.

  Log Message:
  -----------
  vhost-user: Add VHOST_USER_POSTCOPY_END message

This message is sent just before the end of postcopy to get the
client to stop using userfault since we wont respond to any more
requests.  It should close userfaultfd so that any other pages
get mapped to the backing file automatically by the kernel, since
at this point we know we've received everything.

  vhost: Huge page align and merge

Align RAMBlocks to page size alignment, and adjust the merging code
to deal with partial overlap due to that alignment.

This is needed for postcopy so that we can place/fetch whole hugepages
when under userfault.

  Log Message:
  -----------
  postcopy: Allow shared memory

Now that we have the mechanisms in here, allow shared memory in a
postcopy.

Note that QEMU can't tell who all the users of shared regions are
and thus can't tell whether all the users of the shared regions
have appropriate support for postcopy.  Those devices that explicitly
support shared memory (e.g. vhost-user) must check, but it doesn't
stop weirder configurations causing problems.
