Some static scan tool may regard CurrentRsdtEntry to be potentially
referenced to NULL pointer if CurrentRsdtEntry == NULL is used in
the right above if condition judgment.
CopyMem (CurrentRsdtEntry, CurrentRsdtEntry + 1, (*NumberOfTableEntries - Index) * sizeof (UINT32));
It is introduced by commit f9bbb8d9c3.
To avoid it and have same style with
"((Xsdt == NULL) || CurrentTablePointer64 == (UINT64) (UINTN) Table->Table)",
use Rsdt instead of CurrentRsdtEntry to check against NULL.

The assignment of CurrentRsdtEntry and its subsequent dereference are
subject to the same condition, but for some reason, VS2008 does not see
that and warns about the dereference possibly involving an uninitialized
pointer. Since the single statememt between the blocks is unrelated, we
can just move it and merge the two conditional blocks together.

AARCH64 systems never require compatibility with legacy ACPI OSes, and
may not have any 32-bit addressable system RAM. To support ACPI on these
systems, we need to be able to relax the 4 GB allocation restriction.
So add a PCD PcdAcpiExposedTableVersions containing a bitmask describing
which ACPI versions are targeted, and wire it up it up to the memory
allocation calls in AcpiTableDxe/AcpiTableProtocol.c. I.e., if ACPI v1.0b
is not among the supported versions, the memory allocations are not limited
to 4 GB, and only table types that carry 64-bit addresses are emitted.
Note that this will inhibit the publishing of any tables that carry only
32-bit addresses, i.e., RSDPv1, RSDTv1 and RSDTv3.

We are going to reduce reserved memory consumption by page table buffer,
then OS can have more available memory to use.
Take PhysicalAddressBits = 48 and 2MB page granularity as example,
1:1 Virtual to Physical identity mapping page table buffer needs to be
((512 + 1) * 512 + 1) * 4096 = 1075843072 bytes = 0x40201000 bytes.
Current BootScriptExecutorDxe handles > 4G request by page fault because
S3ResumePeim only builds 4G page table when long mode waking vector is
not needed, but BootScriptExecutorDxe still assume the page table buffer for
page table is at 1:1 Virtual to Physical identity mapping.
To reduce reserved memory consumption, the code is updated to only use
8 extra pages to handles > 4G request by page fault.
Another, when both BIOS and OS wants long mode waking vector,
S3ResumePei should have established 1:1 Virtual to Physical identity mapping
page table for ACPI spec requirement, so no need to hook page fault handler.

UEFI spec has clear description below:
Configuration Table Groups
The GUID for a configuration table also defines a corresponding event group GUID with the same value.
If the data represented by a configuration table is changed,
InstallConfigurationTable() should be called.
When InstallConfigurationTable() is called, the corresponding event is signaled.
When this event is signaled,
any components that cache information from the configuration table can optionally update their cached state.
For example, EFI_ACPI_TABLE_GUID defines a configuration table for ACPI data.
When ACPI data is changed, InstallConfigurationTable() is called.
During the execution of InstallConfigurationTable(),
a corresponding event group with EFI_ACPI_TABLE_GUID is signaled,
allowing an application to invalidate any cached ACPI data.
But current implementation only InstallConfigurationTable() at first time ACPI data change.
if (((Version & EFI_ACPI_TABLE_VERSION_1_0B) != 0) &&
!AcpiTableInstance->TablesInstalled1) {
Status = gBS->InstallConfigurationTable (&gEfiAcpi10TableGuid, AcpiTableInstance->Rsdp1);
if (EFI_ERROR (Status)) {
return EFI_ABORTED;
}
AcpiTableInstance->TablesInstalled1 = TRUE;
}
if (((Version & ACPI_TABLE_VERSION_GTE_2_0) != 0) &&
!AcpiTableInstance->TablesInstalled3) {
Status = gBS->InstallConfigurationTable (&gEfiAcpiTableGuid, AcpiTableInstance->Rsdp3);
if (EFI_ERROR (Status)) {
return EFI_ABORTED;
}
AcpiTableInstance->TablesInstalled3= TRUE;
}
The AcpiTableInstance->TablesInstalled1 and AcpiTableInstance->TablesInstalled3 conditional judgment need to be removed.

The code in AcpiTableDxe handles the installation of FADT and FACS in both
possible orders. In the [FADT, FACS] installation order, the FACS is at
once linked into the FADT. In the [FACS, FADT] installation order, the
FACS is stashed temporarily, and it is linked into the FADT when the FADT
is installed later.
According to the ACPI specification, *at most one* of FADT.FirmwareCtrl
and FADT.XFirmwareCtrl may be nonzero. The code is aware of this
requirement, and it never sets both of them to nonzero values at once.
However, the code doesn't expect the following:
- The caller first installs the FACS, which is stashed. The address that
is saved happens to fall below 4GB.
- The caller then installs a FADT, with a zero FirmwareCtrl field, and a
nonzero (pre-populated) XFirmwareCtrl field.
In this case the code sets FADT.FirmwareCtrl to the less-than-4GB address
of the stashed FACS, and leaves the different nonzero value in
FADT.XFirmwareCtrl. This violates the ACPI specification.
Prevent this by always zeroing the field that we do *not* set.
