The cpu topology property CpuTopology is added to the MachineState
and its members are initialized with the leagcy global smp variables.
From this commit, the code in the system emulation mode is supposed to
use cpu topology variables from MachineState instead of the global ones
defined in vl.c and there is no semantic change.

To get rid of the global smp_* variables we're currently using, it's recommended
to pass MachineState in the list of incoming parameters for functions that use
global smp variables, thus some redundant parameters are dropped. It's applied
for legacy smbios_*(), *_machine_reset(), hot_add_cpu() and mips *_create_cpu().

Basically, the context could get the MachineState reference via call
chains or unrecommended qdev_get_machine() in !CONFIG_USER_ONLY mode.
A local variable of the same name would be introduced in the declaration
phase out of less effort OR replace it on the spot if it's only used
once in the context. No semantic changes.

From: Like Xu <like.xu@linux.intel.com>
The global smp variables in riscv are replaced with smp machine properties.
A local variable of the same name would be introduced in the declaration
phase if it's used widely in the context OR replace it on the spot if it's
only used once. No semantic changes.

The global smp variables in s390x are replaced with smp machine properties.
A local variable of the same name would be introduced in the declaration
phase if it's used widely in the context OR replace it on the spot if it's
only used once. No semantic changes.

The global smp variables in i386 are replaced with smp machine properties.
To avoid calling qdev_get_machine() as much as possible, some related funtions
for acpi data generations are refactored. No semantic changes.
A local variable of the same name would be introduced in the declaration
phase if it's used widely in the context OR replace it on the spot if it's
only used once. No semantic changes.

The global smp variables in arm are replaced with smp machine properties.
The init_cpus() and *_create_rpu() are refactored to pass MachineState.
A local variable of the same name would be introduced in the declaration
phase if it's used widely in the context OR replace it on the spot if it's
only used once. No semantic changes.

From: Like Xu <like.xu@linux.intel.com>
The global smp variables in alpha/hppa/mips/openrisc/sparc*/xtensa codes
are replaced with smp properties from MachineState.
A local variable of the same name would be introduced in the declaration
phase if it's used widely in the context OR replace it on the spot if it's
only used once. No semantic changes.

The global smp variables in vl.c are completely replaced with machine properties.
Form this commit, the smp_cpus/smp_cores/smp_threads/max_cpus are deprecated
and only machine properties within MachineState are fully applied and enabled.

The die-level as the first PC-specific cpu topology is added to the leagcy
cpu topology model, which has one die per package implicitly and only the
numbers of sockets/cores/threads are configurable.
In the new model with die-level support, the total number of logical
processors (including offline) on board will be calculated as:
#cpus = #sockets * #dies * #cores * #threads
and considering compatibility, the default value for #dies would be
initialized to one in x86_cpu_initfn() and pc_machine_initfn().

To support multiple dies configuration on PCMachine, the best place to
set CPUX86State->nr_dies with requested PCMachineState->smp_dies is in
pc_new_cpu() and pc_cpu_pre_plug(). Refactoring pc_new_cpu() is applied
and redundant parameter "const char *typename" would be removed.

The field die_id (default as 0) and has_die_id are introduced to X86CPU.
Following the legacy smp check rules, the die_id validity is added to
the same contexts as leagcy smp variables such as hmp_hotpluggable_cpus(),
machine_set_cpu_numa_node(), cpu_slot_to_string() and pc_cpu_pre_plug().

From: Like Xu <like.xu@linux.intel.com>
In new sockets/dies/cores/threads model, the apicid of logical cpu could
imply die level info of guest cpu topology thus x86_apicid_from_cpu_idx()
need to be refactored with #dies value, so does apicid_*_offset().
To keep semantic compatibility, the legacy pkg_offset which helps to
generate CPUIDs such as 0x3 for L3 cache should be mapping to die_offset.

QEMU will crash when device-memory-region-size property is read if ms->device_memory
wasn't initialized yet.
Crash can be reproduced with:
$QEMU -preconfig -qmp unix:qmp_socket,server,nowait &
./scripts/qmp/qom-get -s qmp_socket /machine.device-memory-region-size
Instead of crashing return 0 if ms->device_memory hasn't been initialized.

Legacy '-numa node,mem' option has a number of issues and mgmt often
defaults to it. Unfortunately it's no possible to replace it with
an alternative '-numa memdev' without breaking migration compatibility.
What's possible though is to deprecate it, keeping option working with
old machine types only.
In order to help users to find out if being deprecated CLI option
'-numa node,mem' is still supported by particular machine type, add new
"numa-mem-supported" property to output of query-machines.
"numa-mem-supported" is set to 'true' for machines that currently support
NUMA, but it will be flipped to 'false' later on, once deprecation period
expires and kept 'true' only for old machine types that used to support
the legacy option so it won't break existing configuration that are using
it.

The parameter allows to configure fake NUMA topology where guest
VM simulates NUMA topology but not actually getting performance
benefits from it. The same or better results could be achieved
using 'memdev' parameter.
Beside of unpredictable performance, '-numa node.mem' option has
other issues when it's used with combination of -mem-path +
+ -mem-prealloc + memdev backends (pc-dimm), breaking binding of
memdev backends since mem-path/mem-prealloc are global and affect
the most of RAM allocations.
It's possible to make memdevs and global -mem-path/mem-prealloc
to play nicely together but that will just complicate already
complicated code and add unobious ways it could break on 2
different memmory allocation pathes and their combinations.
Instead of it, consolidate all guest RAM allocation over memdev
which still allows to create fake NUMA configurations if desired
and leaves one simplifyed code path to consider when it comes
to guest RAM allocation.
To achieve desired simplification deprecate 'mem' parameter as its
ad-hoc partitioning of initial RAM MemoryRegion can't be translated
to memdev based backend transparently to users and in compatible
manner (migration wise).
Later down the road that will allow to consolidate means of how
guest RAM is allocated and would permit us to clean up quite
a bit memory allocations and numa code, leaving only 'memdev'
implementation in place.

Implicit RAM distribution between nodes has exactly the same issues as:
"numa: deprecate 'mem' parameter of '-numa node' option"
only with QEMU being the user that's 'adding' 'mem' parameter.
Deprecate it, to get it out of the way so that we could consolidate
guest RAM allocation using memory backends making it consistent and
possibly later on transition to using memory devices instead of

Commit 2d384d7c8 broken the build when built with:
configure --without-default-devices --disable-user
The reason was the conversion of cpu->hyperv_synic to
cpu->hyperv_synic_kvm_only although the rest of the patch introduces a
feature checking mechanism. So I've fixed the KVM_EXIT_HYPERV_SYNIC in
hyperv-stub to do the same feature check as in the real hyperv.c

Fallback might affect guest or worse whole host performance
or functionality if backing file were used to share guest RAM
with another process.
Patch deprecates fallback so that we could remove it in future
and ensure that QEMU will provide expected behavior and fail if
it can't use user provided backing file.

If cpu->host_phys_bits_limit is set, QEMU will make
cpu->phys_bits be lower than host_phys_bits on some cases. This
triggers a warning that was supposed to be printed only if
phys-bits was explicitly set in the command-line.
Reorder the code so the value of cpu->phys_bits is validated
before the cpu->host_phys_bits handling. This will avoid
unexpected warnings when cpu->host_phys_bits_limit is set.

The current default value for hv-spinlocks is 0xFFFFFFFF (meaning
"never retry"). However, the value is stored as a signed
integer, making the getter of the hv-spinlocks QOM property
return -1 instead of 0xFFFFFFFF.
Fix this by changing the type of X86CPU::hyperv_spinlock_attempts
to uint32_t. This has no visible effect to guest operating
systems, affecting just the behavior of the QOM getter.

X86CPU.hv-spinlocks is a uint32 property that has a special setter
validating the value to be no less than 0xFFF and no bigger than
UINT_MAX. The latter check is redundant; as for the former, there
appears to be no reason to prohibit the user from setting it to a lower
value.
So nuke the dedicated getter/setter pair and convert 'hv-spinlocks' to a
regular uint32 property.

The variable is completely unused, probably a leftover from
previous code clean up.

The CPUID.1F as Intel V2 Extended Topology Enumeration Leaf would be
exposed if guests want to emulate multiple software-visible die within
each package. Per Intel's SDM, the 0x1f is a superset of 0xb, thus they
can be generated by almost same code as 0xb except die_offset setting.
If the number of dies per package is greater than 1, the cpuid_min_level
would be adjusted to 0x1f regardless of whether the host supports CPUID.1F.
Likewise, the CPUID.1F wouldn't be exposed if env->nr_dies < 2.

From: Like Xu <like.xu@linux.intel.com>
To make smp_parse() more flexible and expansive, a smp_parse function
pointer is added to MachineClass that machine types could override.
The generic smp_parse() code in vl.c is moved to hw/core/machine.c, and
become the default implementation of MachineClass::smp_parse. A PC-specific
function called pc_smp_parse() has been added to hw/i386/pc.c, which in
this patch changes nothing against the default one .

For PC target, users could configure the number of dies per one package
via command line with this patch, such as "-smp dies=2,cores=4".
The parsing rules of new cpu-topology model obey the same restrictions/logic
as the legacy socket/core/thread model especially on missing values computing.

Export machine type deprecation status through the query-machines
QMP command. With this, libvirt and management software will be
able to show this information to users and/or suggest changes to
VM configuration to avoid deprecated machines.

When introducing versioned CPU models, the string at
X86CPUDefinition::model_id might not be the model-id we'll really
use. Instantiate a CPU object and check the model-id property on
"-cpu help"

Add support for registration of multiple versions of CPU models.
The existing CPU models will be registered with a "-v1" suffix.
The -noTSX, -IBRS, and -IBPB CPU model variants will become
versions of the original models in a separate patch, so
make sure we register no versions for them.

Add versions of CPU models that are equivalent to their -IBRS,
-noTSX and -IBRS variants.
The separate variants will eventually be removed and become
aliases for these CPU versions.

This will make unversioned CPU models behavior depend on the
machine type:
* "pc-*-4.0" and older will not report them as aliases.
This is done to keep compatibility with older QEMU versions
after management software starts translating aliases.
* "pc-*-4.1" will translate unversioned CPU models to -v1.
This is done to keep compatibility with existing management
software, that still relies on CPU model runnability promises.
* "none" will translate unversioned CPU models to their latest
version. This is planned become the default in future machine
types (probably in pc-*-4.3).

+@subsection Runnability guarantee of CPU models (since 4.1.0)
+
+Previous versions of QEMU never changed existing CPU models in
+ways that introduced additional host software or hardware
+requirements to the VM. This allowed management software to
+safely change the machine type of an existing VM without
+introducing new requirements ("runnability guarantee"). This
+prevented CPU models from being updated to include CPU
+vulnerability mitigations, leaving guests vulnerable in the
+default configuration.
+
+The CPU model runnability guarantee won't apply anymore to
+existing CPU models. Management software that needs runnability
+guarantees must resolve the CPU model aliases using te
+``alias-of'' field returned by the ``query-cpu-definitions'' QMP
+command.

Add new version of Cascadelake-Server CPU model, setting
stepping=5 and enabling the IA32_ARCH_CAPABILITIES MSR
with some flags.
The new feature will introduce a new host software requirement,
breaking our CPU model runnability promises. This means we can't
enable the new CPU model version by default in QEMU 4.1, because
management software isn't ready yet to resolve CPU model aliases.
This is why "pc-*-4.1" will keep returning Cascadelake-Server-v1
if "-cpu Cascadelake-Server" is specified.
Includes a test case to ensure the right combinations of
machine-type + CPU model + command-line feature flags will work
as expected.

This will help us avoid spurious warnings during "make check".
Note that this will silence the warnings generated by
tests/numa-test, but not the ones generated by
tests/bios-tables-test. We still need to change
tests/bios-tables-test to use "-numa ...,memdev=" to silence
these warnings.

QEMU fails to start if memory-less node is present when memdev
is used
qemu-system-x86_64 -object memory-backend-ram,id=ram0,size=128M \
-numa node -numa node,memdev=ram0
with error:
"memdev option must be specified for either all or no nodes"
which works as expected if legacy 'mem' is used.
Fix check to make memory-less nodes valid when memdev option is used
but still disallow mix of mem and memdev options.

Hi; this fails to link (all platforms):
hw/riscv/sifive_u.o: In function `riscv_sifive_u_soc_realize':
/home/petmay01/linaro/qemu-for-merges/hw/riscv/sifive_u.c:356:

/home/petmay01/linaro/qemu-for-merges/hw/riscv/sifive_u.c:358:
undefined reference to `smp_cpus'
collect2: error: ld returned 1 exit status
I guess you have a conflict with the recent riscv pullreq.
thanks
