Add Intel Processor Trace related definition. It also add
corresponding part to kvm_get/set_msr and vmstate.
Backports commit b77146e9a129bcdb60edc23639211679ae846a92 from qemu
Expose Intel Processor Trace feature to guest.
To make Intel PT live migration safe and get same CPUID information
with same CPU model on diffrent host. CPUID[14] is constant in this
patch. Intel PT use EPT is first supported in IceLake, the CPUID[14]
get on this machine as default value. Intel PT would be disabled
if any machine don't support this minial feature list.
Backports commit e37a5c7fa459558b5020588994707fe3fdd6616e from qemu
Add KVM_HINTS_DEDICATED performance hint, guest checks this feature bit
to determine if they run on dedicated vCPUs, allowing optimizations such
as usage of qspinlocks.
Backports commit be7773268d98176489483a315d3e2323cb0615b9 from qemu
This MSR returns the number of #SMIs that occurred on
CPU since boot.
KVM commit 52797bf9a875 ("KVM: x86: Add emulation of MSR_SMI_COUNT")
introduced support for emulating this MSR.
This commit adds support for QEMU to save/load this
MSR for migration purposes.

When SEV is enabled, CPUID 0x8000_001F should provide additional
information regarding the feature (such as which page table bit is used
to mark the pages as encrypted etc).
The details for memory encryption CPUID is available in AMD APM

Backports commit 273401809c8a8330e5430f2c958467efa7079b2c from qemu
Now we have a working '-cpu max', the linux-user-only
'any' CPU is pretty much the same thing, so implement it
that way.
For the moment we don't add any of the extra feature bits
to the system-emulation "max", because we don't set the
ID register bits we would need to to advertise those
features as present.
Backports commit a0032cc5427d0d396aa0a9383ad9980533448ea4 from qemu
Add support for "-cpu max" for ARM guests. This CPU type behaves
like "-cpu host" when KVM is enabled, and like a system CPU with
the maximum possible feature set otherwise. (Note that this means
it won't be migratable across versions, as we will likely add
features to it in future.)
Backports commit bab52d4bba3f22921a690a887b4bd0342f2754cd from qemu
The cortex A53 TRM specifies that bits 24 and 25 of the L2CTLR register
specify the number of cores in the processor, not the total number of
cores in the system. To report this correctly on machines with multiple
CPU clusters (ARM's big.LITTLE or Xilinx's ZynqMP) we need to allow
the machine to overwrite this value. To do this let's add an optional
property.
