Heap guard makes use of paging mechanism to implement its functionality. But
there's no protocol or library available to change page attribute in SMM mode.
A new protocol gEdkiiSmmMemoryAttributeProtocolGuid is introduced to make it
happen. This protocol provide three interfaces
struct _EDKII_SMM_MEMORY_ATTRIBUTE_PROTOCOL {
EDKII_SMM_GET_MEMORY_ATTRIBUTES GetMemoryAttributes;
EDKII_SMM_SET_MEMORY_ATTRIBUTES SetMemoryAttributes;
EDKII_SMM_CLEAR_MEMORY_ATTRIBUTES ClearMemoryAttributes;
};
Since heap guard feature need to update page attributes. The page table
should not set to be read-only if heap guard feature is enabled for SMM
mode. Otherwise this feature cannot work.

For some special platforms (such as Ovmf), it is possible
that, some APs start up *and finish* before the remaining
APs start up *at all*. In this case, the enhance

This change remove check CpuMpData->CpuCount logic to let old

In current implementation, CPU initialized can be done in PEI
or DXE phase. PEI uses CpuFeaturesPei and Dxe uses CpuFeaturesDxe.
If CPU initialized in PEI phase, CpuFeaturesDxe driver will
not be used. This driver will install gEdkiiCpuFeaturesInitDoneGuid
protocol after it initializes the CPU.
Some drivers depend on this protocol to dispatch themselves. If
CpuFeaturesDxe not been used, these drivers will not be dispatched.
This patch fix the above issue. If Cpu initialized in PEI
phase, it also report a guid HOB for CpuFeaturesDxe.
CpuFeaturesDxe will check this HOB first. If it found this
HOB, it just install gEdkiiCpuFeaturesInitDoneGuid protocol,
else it will also do the CPU initialization.

The new algorithm converts the problem calculating optimal
MTRR settings (using least MTRR registers) to the problem finding
the shortest path in a graph.
The memory required in extreme but rare case can be up to 256KB,
so using local stack buffer is impossible considering current
DxeIpl only allocates 128KB stack.
The patch changes existing MtrrSetMemoryAttributeInMtrrSettings() and
MtrrSetMemoryAttribute() to use the 4-page stack buffer for
calculation. The two APIs return BUFFER_TOO_SMALL when the buffer
is too small for calculation.
The patch adds a new API MtrrSetMemoryAttribute*s*InMtrrSettings() to
set multiple-range attributes in one function call.
Since every call to MtrrSetMemoryAttributeInMtrrSettings (without-s)
or MtrrSetMemoryAttribute() requires to calculate the MTRRs for the
whole physical memory, combining multiple calls in one API can
significantly reduce the calculation time.
In theory, if N times of call to without-s API costs N seconds,
the new API only costs 1 second.
The new API uses the buffer supplied from caller to calculate
MTRRs and returns BUFFER_TOO_SMALL when the buffer is too small for
calculation.
Test performed:
1. Random test
a. Generate random memory settings, use the new algorithm to
calculate the MTRRs.
b. Read back the MTRRs and check the memory settings match
the desired memory settings.
c. Repeat the above #1 and #2 100000 times.
2. OVMF 32PEI + 64DXE boot to shell.

Fix NASM compatibility issues with XCODE5 tool chain.
The XCODE5 tool chain for X64 builds using PIE (Position
Independent Executable). For most assembly sources using
PIE mode does not cause any issues.
However, if assembly code is copied to a different address
(such as AP startup code in the MpInitLib), then the
X64 assembly source must be implemented to be compatible
with PIE mode that uses RIP relative addressing.
The specific changes in this patch are:
* Use LEA instruction instead of MOV instruction to lookup
the addresses of functions.
* The assembly function RendezvousFunnelProc() is copied
below 1MB so it can be executed as part of the MpInitLib
AP startup sequence. RendezvousFunnelProc() calls the
external function InitializeFloatingPointUnits(). The
absolute address of InitializeFloatingPointUnits() is
added to the MP_CPU_EXCHANGE_INFO structure that is passed
to RendezvousFunnelProc().
