Eric Dong bf252e29a5 UefiCpuPkg/LocalApicLib: Exclude second SendIpi sequence on AMD processors.
On AMD processors the second SendIpi in the SendInitSipiSipi and
SendInitSipiSipiAllExcludingSelf routines is not required, and may cause
undesired side-effects during MP initialization.

This patch leverages the StandardSignatureIsAuthenticAMD check to exclude
the second SendIpi and its associated MicroSecondDelay (200).

Laszlo Ersek 4af3ae1463 UefiCpuPkg/LocalApicLib: fix feature test for Extended Topology CPUID leaf
According to the Intel SDM (325462-060US / September 2016),

> INPUT EAX = 0BH: Returns Extended Topology Information
>
> [...] Software must detect the presence of CPUID leaf 0BH by verifying
> (a) the highest leaf index supported by CPUID is >= 0BH, and
> (b) CPUID.0BH:EBX[15:0] reports a non-zero value. [...]

The LocalApicLib instances in UefiCpuPkg do not perform check (b).

This causes an actual bug in the following OVMF setup:

- Intel W3550 host processor <http://ark.intel.com/products/39720/>,

- the QEMU/KVM guest's VCPU model is set to "host", that is, "the CPU
  visible to the guest should be exactly the same as the host CPU".

In the GetInitialApicId() function, check (a) passes: the CPUID level of
the W3550 is exactly 11 decimal. However, leaf 11 itself is not supported,
therefore EDX is set to zero:

> If a value entered for CPUID.EAX is less than or equal to the maximum
> input value and the leaf is not supported on that processor then 0 is
> returned in all the registers.

Because we don't check (b), we return 0 as initial APIC ID on the BSP and
on all of the APs as well.

Add the missing check.

#define MSR_IA32_APIC_BASE_ADDRESS is duplicated with #define MSR_IA32_APIC_BASE
defined in UefiCpuPkg/Include/Register/ArchitecturalMsr.h, so we could remove it

Structure MSR_IA32_APIC_BASE conflicts with #define MSR_IA32_APIC_BASE defined
in UefiCpuPkg/Include/Register/ArchitecturalMsr.h, so we could remove it and
update the modules to use structure MSR_IA32_APIC_BASE_REGISTER from
ArchitecturalMsr.h.

v5:
