When the guest unplugs the emulated NICs, cleanup the peer for each NIC
as it is not needed anymore. Most importantly, this allows the tap
interfaces which QEMU holds open to be closed and removed.

pc.h and sysemu/kvm.h are also included from common code (where
CONFIG_KVM is not available), so the #defines that depend on CONFIG_KVM
should not be declared here to avoid that anybody is using them in a
wrong way. Since we're also going to poison CONFIG_KVM for common code,
let's move them to kvm_i386.h instead. Most of the dummy definitions
from sysemu/kvm.h are also unused since the code that uses them is
only compiled for CONFIG_KVM (e.g. target/i386/kvm.c), so the unused
defines are also simply dropped here instead of being moved.

Migration is broken after the vfio integration work:
qemu-kvm: AHCI: Failed to start FIS receive engine: bad FIS receive buffer address
qemu-kvm: Failed to load ich9_ahci:ahci
qemu-kvm: error while loading state for instance 0x0 of device '0000:00:1f.2/ich9_ahci'
qemu-kvm: load of migration failed: Operation not permitted
The problem is that vfio work introduced dynamic memory region
switching (actually it is also used for future PT mode), and this memory
region layout is not properly delivered to destination when migration
happens. Solution is to rebuild the layout in post_load.

to a local_err variable, then through error_propagate() pass to

avoid the extra local_err and error_propagate(), drop it and use
errp instead.

The VT-d spec (section 6.5.2) prescribes software to zero the
Invalidation Queue Tail Register before enabling the VTD_GCMD_QIE
Global Command Register bit. Windows Server 2012 R2 and possibly
other older Windows versions violate the protocol and set a
non-zero queue tail first, which in effect makes them crash early
on boot with -device intel-iommu,intremap=on.
This commit relaxes the check and instead of failing to enable
VTD_GCMD_QIE with vtd_err_qi_enable, it behaves as if the tail
register was set just after enabling VTD_GCMD_QIE
(see vtd_handle_iqt_write).

Switch to use QNum/uint where appropriate to remove i64 limitation.
The input visitor will cast i64 input to u64 for compatibility
reasons (existing json QMP client already use negative i64 for large
u64, and expect an implicit cast in qemu).
Note: before the patch, uint64_t values above INT64_MAX are sent over
json QMP as negative values, e.g. UINT64_MAX is sent as -1. After the
patch, they are sent unmodified. Clearly a bug fix, but we have to
consider compatibility issues anyway. libvirt should cope fine,
because its parsing of unsigned integers accepts negative values
modulo 2^64. There's hope that other clients will, too.

Commit e987c37aee ("hw/i386: check if
nvdimm is enabled before plugging") introduced a check to reject nvdimm
hotplug if -machine pc,nvdimm=on was not given.
This check executes after pc_dimm_memory_plug() has already completed
and does not reverse the effect of this function in the case of failure.
Perform the check before calling pc_dimm_memory_plug(). This fixes the
following abort:
$ qemu -M accel=kvm -m 1G,slots=4,maxmem=8G \
-object memory-backend-file,id=mem1,share=on,mem-path=nvdimm.dat,size=1G
(qemu) device_add nvdimm,memdev=mem1
nvdimm is not enabled: missing 'nvdimm' in '-M'
(qemu) device_add nvdimm,memdev=mem1

Do an update of system_time_msr address every time before reading

There is no other code paths which ensure that qemu has an up-to-date
value of system_time_msr. So, force this update on guest's tsc_timestamp
reading.
This bug causes effect on those nested setups which turn off TPR access
interception for L2 guests and that access being intercepted by L0 doesn't
show up in L1.
Linux bootstrap initiate kvmclock before APIC initializing causing TPR access.
That's why on L1 guests, having TPR interception turned on for L2, the effect
of the bug is not revealed.

system_time_msr address every time it is needed.

It fixes/add missing _PXM object for non mapped CPU (x86)
and missing fdt node (virt-arm).
It ensures that possible_cpus contains complete mapping if
numa is enabled by the time machine_init() is executed.
As result non completely mapped CPUs:
1) appear in ACPI/fdt blobs
2) QMP query-hotpluggable-cpus command shows bound nodes for such CPUs
3) allows to drop checks for has_node_id in numa only code,
reducing number of invariants incomplete mapping could produce
4) moves fixup/implicit node init from runtime numa_cpu_pre_plug()
(when CPU object is created) to machine_numa_finish_init() which
helps to fix [1, 2] and make possible_cpus complete source
of numa mapping available even before CPUs are created.

For reasons unknown, Windows won't online all memory, both at command
line and hot-plugged later, unless the hotplug mem hole SRAT entry
specifies a node greater than or equal to the ones where memory is
added.
Using the highest node on the machine makes recent versions of Windows
happy.
With this example command line:
... \
-m 1024,slots=4,maxmem=32G \
-numa node,nodeid=0 \
-numa node,nodeid=1 \
-numa node,nodeid=2 \
-numa node,nodeid=3 \
-object memory-backend-ram,size=1G,id=mem-mem1 \
-device pc-dimm,id=dimm-mem1,memdev=mem-mem1,node=1
Windows reports a total of 1G of RAM without this commit and the expected
2G with this commit.

When device-iotlb is not specified, we should fail this check. A new
function vtd_ce_type_check() is introduced.
While I'm at it, clean up the vtd_dev_to_context_entry() a bit - replace
many "else if" usage into direct if check. That'll make the logic more
clear.

This patch converts the old "is_write" bool into IOMMUAccessFlags. The
difference is that "is_write" can only express either read/write, but
sometimes what we really want is "none" here (neither read nor write).
Replay is an good example - during replay, we should not check any RW
permission bits since thats not an actual IO at all.

Time to wire up all the call sites that request a shutdown or
reset to use the enum added in the previous patch.
It would have been less churn to keep the common case with no
arguments as meaning guest-triggered, and only modified the
host-triggered code paths, via a wrapper function, but then we'd
still have to audit that I didn't miss any host-triggered spots;
changing the signature forces us to double-check that I correctly
categorized all callers.
Since command line options can change whether a guest reset request
causes an actual reset vs. a shutdown, it's easy to also add the
information to reset requests.

We want to track why a guest was shutdown; in particular, being able
to tell the difference between a guest request (such as ACPI request)
and host request (such as SIGINT) will prove useful to libvirt.
Since all requests eventually end up changing shutdown_requested in
vl.c, the logical change is to make that value track the reason,
rather than its current 0/1 contents.
Since command-line options control whether a reset request is turned
into a shutdown request instead, the same treatment is given to
reset_requested.
This patch adds an internal enum ShutdownCause that describes reasons
that a shutdown can be requested, and changes qemu_system_reset() to
pass the reason through, although for now nothing is actually changed
with regards to what gets reported. The enum could be exported via
QAPI at a later date, if deemed necessary, but for now, there has not
been a request to expose that much detail to end clients.
For the most part, we turn 0 into SHUTDOWN_CAUSE_NONE, and 1 into
SHUTDOWN_CAUSE_HOST_ERROR; the only specific case where we have enough
information right now to use a different value is when we are reacting
to a host signal. It will take a further patch to edit all call-sites
that can trigger a reset or shutdown request to properly pass in any
other reasons; this patch includes TODOs to point such places out.
qemu_system_reset() trades its 'bool report' parameter for a
'ShutdownCause reason', with all non-zero values having the same
effect; this lets us get rid of the weird #defines for VMRESET_*
as synonyms for bools.

A bunch of fixes that missed the release.
Most notably we are reverting shpc back to enabled by default state
as guests uses that as an indicator that hotplug is supported
(even though it's unused). Unfortunately we can't fix this
on the stable branch since that would break migration.
