The definition of IA32_MAP_ATTRIBUTE has 64 bits, and one of the bit
field PageTableBaseAddress is from bit 12 to bit 52. This means if the
compiler treats the 64bits value as two UINT32 value, the field
PageTableBaseAddress spans two UINT32 value. That's why when building in
NOOPT mode in IA32, the below issue is noticed:
unresolved external symbol __allshl
This patch fix the build failure by seperate field PageTableBaseAddress
into two fields, make sure no field spans two UINT32 value.

For different usage, check if the combination for Mask and
Attr is valid when creating or updating page table.
1.For non-present range
1.1Mask.Present is 0 but some other attributes is provided.
This case is invalid.
1.2Mask.Present is 1 and Attr.Present is 0. In this case,all
other attributes should not be provided.
1.3Mask.Present is 1 and Attr.Present is 1. In this case,all
attributes should be provided to intialize the attribute.
2.For present range
2.1Mask.Present is 1 and Attr.Present is 0.In this case, all
other attributes should not be provided.
All other usage for present range is permitted.
In the mentioned cases, 1.2 and 2.1 can be merged into 1 check.

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4337
The default SMBASE for the x86 processor is 0x30000. When
SMI happens, processor runs the SMI handler at SMBASE+0x8000.
Also, the SMM save state area is within SMBASE+0x10000.
One of the SMM initialization from processor perspective is to
relocate and program the new SMBASE (in TSEG range) for each
processor. When the SMBASE relocation happens in a PEI module,
the PEI module shall produce the SMM_BASE_HOB in HOB database
which tells the PiSmmCpuDxeSmm driver (runs at a later phase)
about the new SMBASE for each processor. PiSmmCpuDxeSmm driver
installs the SMI handler at the SMM_BASE_HOB.SmBase[Index]+0x8000
for processor Index. When the HOB doesn't exist, PiSmmCpuDxeSmm
driver shall relocate and program the new SMBASE itself.
This patch adds the SMM Base HOB for any PEI module to do
the SmBase relocation ahead of PiSmmCpuDxeSmm driver and
store the relocated SmBase address in array for each
processor.

VmgExitLib once was designed to provide interfaces to support #VC handler
and issue VMGEXIT instruction. After TDVF (enable TDX feature in OVMF) is
introduced, this library is updated to support #VE as well. Now the name
of VmgExitLib cannot reflect what the lib does.
This patch renames VmgExitLib to CcExitLib (Cc means Confidential
Computing). This is a simple renaming and there is no logic changes.
After renaming all the VmgExitLib related codes are updated with
CcExitLib. These changes are in OvmfPkg/UefiCpuPkg/UefiPayloadPkg.

The lib includes two APIs:
* PageTableMap
It creates/updates mapping from LA to PA.
The implementation only supports paging structures used in 64bit
mode now. PAE paging structure support will be added in future.
* PageTableParse
It parses the page table and returns the mapping relations in an
array of IA32_MAP_ENTRY.
It passed some stress tests. These test code will be upstreamed in
other patches following edk2 Unit Test framework.

VariableSmm and VariableStandaloneMM driver in MdeModulePkg need

Today's code assumes every core contains the same number of threads.
It's not always TRUE for certain model.
Such assumption causes system hang when thread count per core
is different and there is core or package dependency between CPU
features (using CPU_FEATURE_CORE_BEFORE/AFTER,
CPU_FEATURE_PACKAGE_BEFORE/AFTER).
The change removes such assumption by calculating the actual thread
count per package and per core.

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3008
The QemuFlashPtrWrite() flash services runtime uses the GHCB and VmgExit()
directly to perform the flash write when running as an SEV-ES guest. If an
interrupt arrives between VmgInit() and VmgExit(), the Dr7 read in the
interrupt handler will generate a #VC, which can overwrite information in
the GHCB that QemuFlashPtrWrite() has set. This has been seen with the
timer interrupt firing and the CpuExceptionHandlerLib library code,
UefiCpuPkg/Library/CpuExceptionHandlerLib/X64/
Xcode5ExceptionHandlerAsm.nasm and
ExceptionHandlerAsm.nasm
reading the Dr7 register while QemuFlashPtrWrite() is using the GHCB. In
general, it is necessary to protect the GHCB whenever it is used, not just
in QemuFlashPtrWrite().
Disable interrupts around the usage of the GHCB by modifying the VmgInit()
and VmgDone() interfaces:
- VmgInit() will take an extra parameter that is a pointer to a BOOLEAN
that will hold the interrupt state at the time of invocation. VmgInit()
will get and save this interrupt state before updating the GHCB.
- VmgDone() will take an extra parameter that is used to indicate whether
interrupts are to be (re)enabled. Before exiting, VmgDone() will enable
interrupts if that is requested.

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3008
In upcoming patches, the setting of the bits in the GHCB ValidBitmap will
be performed in multiple places. In order to reduce code duplication, add
an interface, VmgSetOffsetValid(), to VmgExitLib library to perform this
function. Also, to keep management of the ValidBitmap within the library,
add an inteface, VmgIsOffsetValid(), to return whether the bit in the
ValidBitmap is set for a specified offset.
The new VmgSetOffsetValid() function is a VOID function and will be an
empty function in the VmgExitLibNull implementation of the VmgExitLib
library.
The new VmgIsOffsetValid() function returns a BOOLEAN to indicate if the
offset is valid. This will always return FALSE in the VmgExitLibNull
implementation of the VmgExitLib library.

Commit c7c964b and dd01704 add header file for FIT table and update
MpInitLib to support FIT based microcode shadow operation. There are
comments that FIT is Intel specific specification instead of industry
standard, which should not be placed in EDK2 MdePkg and UefiCpuPkg.
So this patch adds a platform PPI for the microcode shadow logic, and
remove the FIT related code from EDK2.
The FIT based microcode shadow support will be implemented as a new
platform PEIM in IntelSiliconPkg in edk2-platforms.
This patch doesn't provide a DXE version shadow microcode protocol,
a platform which only uses DxeMpInitLib instance only supports PCD
based microcode shadowing.
A detailed design doc can be found here:
https://edk2.groups.io/g/devel/files/Designs/2020/0214/Support%20
the%202nd%20Microcode%20FV%20Flash%20Region.pdf
TEST: Tested on FIT enabled platform.

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1584
The flow of CPU feature initialization logic is:
1. BSP calls GetConfigDataFunc() for each thread/AP;
2. Each thread/AP calls SupportFunc() to detect its own capability;
3. BSP calls InitializeFunc() for each thread/AP.
There is a design gap in step #3. For a package scope feature that only
requires one thread of each package does the initialization operation,
what InitializeFunc() currently does is to do the initialization
operation only CPU physical location Core# is 0.
But in certain platform, Core#0 might be disabled in hardware level
which results the certain package scope feature isn't initialized at
all.
The patch adds a new field First to indicate the CPU's location in
its parent scope.
First.Package is set for all APs/threads under first package;
First.Core is set for all APs/threads under first core of each
package;
First.Thread is set for the AP/thread of each core.

Commit b3c71b472dff2c02f0cc38d7a1959cfb2ba8420d supported MSR setting
in different scopes. It added below macro:
CPU_FEATURE_THREAD_BEFORE
CPU_FEATURE_THREAD_AFTER
CPU_FEATURE_CORE_BEFORE
CPU_FEATURE_CORE_AFTER
CPU_FEATURE_PACKAGE_BEFORE
CPU_FEATURE_PACKAGE_AFTER
And it re-interpreted CPU_FEATURE_BEFORE as CPU_FEATURE_THREAD_BEFORE
and CPU_FEATURE_AFTER as CPU_FEATURE_THREAD_AFTER.
This patch retires CPU_FEATURE_BEFORE and CPU_FEATURE_AFTER
completely.

This commit will add the definitions for EDKII microcode patch HOB.
The intention of adding this HOB is to provide a scheme to store the below
information:
A. The base address and size of the microcode patches that are being
loaded (from flash) into memory;
B. The information of detected microcode patch for each processor within
the system.
The producer of the HOB will be the UefiCpuPkg/MpInitLib (where the load,
detect and apply of the microcode happen). The consumer of the HOB can be
modules that want to detect/apply the microcode patch by themselves again
later during the boot flow.

The patch moves all files under UefiCpuPkg/Include/Register/ to
MdePkg/Include/Register using following detailed approaches:
1. Move UefiCpuPkg/Include/Register/Amd/ to
MdePkg/Include/Register/Amd folder.
2. Move remaining in UefiCpuPkg/Include/Register/ to
MdePkg/Include/Register/Intel folder.
3. Create wrapper header files under UefiCpuPkg/Include/Register/
to include the accordingly files in MdePkg/Include/Register/Intel.
This is to avoid build break because code in other repos like
edk2-platform includes the file from UefiCpuPkg.
The wrapper header files will be removed after all consumers code
is updated.

for CPUID.1FH because when the structure definitions for CPUID.0BH
can be used for CPUID.1FH.
