Michael Kinney 31b3597ee2 UefiCpuPkg/MtrrLib: Add worker functions not invoke IsMtrrSupported()
Abstract some worker functions not to invoke IsMtrrSupported(). They could be

Jeff Fan 46309b1101 UefiCpuPkg/MtrrLib: Add PCD PcdCpuNumberOfReservedVariableMtrrs
Current MtrrLib reserves 2 variable MTRRs for some legacy OS boot (CSM boots)
may require some MTRRs to be reserved for OS use. But UEFI OS boot will not use
MTRRs.

Per Scott's suggestion in
link: http://article.gmane.org/gmane.comp.bios.edk2.devel/4099
Add one PCD PcdCpuNumberOfReservedVariableMtrrs to specify the number of
variable MTRRs reserved for OS use. Setting its default value to 2 is for
back-compatibility.

SmmCpuFeaturesCompleteSmmReadyToLock() is a hook point to allow
CPU specific code to do more registers setting after
the gEfiSmmReadyToLockProtocolGuid notification is completely processed.
Add SmmCpuFeaturesCompleteSmmReadyToLock() to PerformRemainingTasks() and PerformPreTasks().

SmmCpuFeaturesAllocatePageTableMemory() is an API to allow
CPU to allocate a specific region for storing page tables.
All page table allocation will use AllocatePageTableMemory().

Jeff Fan 4ab4e20f1a UefiCpuPkg/SmmFeatureLib: Check SmmFeatureControl by Code_Access_Chk
Bit SMM_Code_Access_Chk (SMM-RO) in MSR_SMM_MCA_CAP is defined in SDM.
If set to 1 indicates that the SMM code access restriction is supported and the
MSR_SMM_FEATURE_CONTROL is supported.

If this bit is not set, we needn't to access register SmmFetureControl.
Otherwise, #GP exception may happen.
We need to check if SmmFeatureControl support or not by checking
SMM_Code_Access_Chk (SMM-RO) in MSR_SMM_MCA_CAP.

Because MSR_SMM_MCA_CAP is SMM-RO register, we should move this check from
SmmCpuFeaturesLibConstructor (non-SMM) to SmmCpuFeaturesInitializeProcessor
(SMM).

Jeff Fan cf1eb6e6f8 Introduce one PCD PcdCpuInitIpiDelayInMicroSeconds to specify the delay value after sending out INIT IPI instead of hard code 10 MicroSeconds.
Its default value is 10 millisecond per IA32 manual.

jljusten d6d8e8925f BaseUefiCpuLib: Preserve EBX register in InitializeFloatingPointUnits
