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().

There are cases that the operands of an expression are all with rank less
than UINT64/INT64 and the result of the expression is explicitly cast to
UINT64/INT64 to fit the target size.
An example will be:
UINT32 a,b;
// a and b can be any unsigned int type with rank less than UINT64, like
// UINT8, UINT16, etc.
UINT64 c;
c = (UINT64) (a + b);
Some static code checkers may warn that the expression result might
overflow within the rank of "int" (integer promotions) and the result is
then cast to a bigger size.
The commit refines codes by the following rules:
1). When the expression is possible to overflow the range of unsigned int/
int:
c = (UINT64)a + b;
2). When the expression will not overflow within the rank of "int", remove
the explicit type casts:
c = a + b;
3). When the expression will be cast to pointer of possible greater size:
UINT32 a,b;
VOID *c;
c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b);
4). When one side of a comparison expression contains only operands with
rank less than UINT32:
UINT8 a;
UINT16 b;
UINTN c;
if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...}
For rule 4), if we remove the 'UINTN' type cast like:
if (a + b > c) {...}
The VS compiler will complain with warning C4018 (signed/unsigned
mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.

Split the default implementation of the SmmCpuFeaturesLib
into two files to prepare for the addition of the STM
specific SmmCpuFeaturesLib implementation. The STM
specific implementation installs a different SMI entry
handler and initialize the MSEG specific MSR at the end
of SmmCpuFeaturesInitializeProcessor().
This patch does not introduce any functional changes
to the default implementation of the SmmCpuFeaturesLib.

Sometimes a platform knows exactly how many CPUs it has at boot. It should
be able to
- set PcdCpuMaxLogicalProcessorNumber dynamically to this number,
- set PcdCpuApInitTimeOutInMicroSeconds to a very long time (for example
MAX_UINT32, approx. 71 minutes),
- and expect that MpInitLib wait exactly as long as necessary for all APs
to report in.
Other platforms should be able to continue setting a reasonably large
upper bound on supported CPUs, and waiting for a reasonable, fixed amount
of time for all APs to report in.
Add this functionality. The TimedWaitForApFinish() function will return
when all APs have reported in, or the timeout has expired -- whichever
happens first.
(Accessing these PCDs dynamically is safe. The PEI and DXE phase instances
of this library are restricted to PEIM and DXE_DRIVER client modules, thus
the PCD accesses cannot be linked into runtime code.)

For long mode DXE, we will disable paging on AP to protected mode to execute AP
safe loop code in reserved memory range under 4GB. But we forget to allocate
stack for AP under 4GB and AP still are using original AP stack. If original AP
stack is larger than 4GB, it cannot be used after AP is transferred to protected
mode. Besides MwaitSupport == TRUE, AP stack is still required during phase of
disabling paging in long mode DXE.
Moreover, even though AP stack is always under 4GB (a) in Ia32 DXE and (b) with
this patch, after transferring to protected mode from X64 DXE, AP stack
(in BootServiceData) maybe crashed by OS after Exit Boot Service event.
This fix is to allocate reserved memory range under 4GB together with AP safe
loop code. APs will switch to new stack in safe loop code.

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 "GetApicId" sections in the Ia32 and X64 "MpFuncs.nasm" files 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".
Under "GetApicId", 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), the "GetProcessorNumber" section of the code
is reached with an initial APIC ID of 0 in EDX on all of the APs. Given
that "GetProcessorNumber" searches the
"MP_CPU_EXCHANGE_INFO.CpuInfo[*].InitialApicId" fields for a match, all
APs enter ApWakeupFunction() with an identical "NumApsExecuting"
parameter. This results in unpredictable guest behavior (crashes, reboots,
hangs etc).
Reorganize the "GetApicId" section and add the missing check in both
assembly files.

The cached "CPU_INFO_IN_HOB.ApTopOfStack" field currently has type UINT32.
This is not ideal because the AP stacks are located within
"CpuMpData->Buffer", which is allocated with a plain AllocatePages() call
in MpInitLibInitialize():
platform CpuMpPei included PEI RAM > 4GB result
-------- ----------------- ------------- ------
Ia32 * n/a good
Ia32X64 no n/a BAD
Ia32X64 yes n/a good
X64 no * BAD
X64 yes no good
X64 yes yes BAD
- If we are on an Ia32X64 or X64 platform that does not include CpuMpPei,
then CpuDxe cannot reuse the CPU_INFO_IN_HOB structures preallocated by
CpuMpPei (through the CpuInitMpLib GUID HOB), and then AllocatePages()
-- invoked first in 64-bit DXE -- could return an address outside of
32-bit address space.
- If we are on an X64 platform where the permanent PEI RAM extends above
the 32-bit address space, then the same issue can surface even if
CpuMpPei is included: even the original allocation of the
CPU_INFO_IN_HOB structures, by CpuMpPei, could be satisfied from above
4GB.
The original "AP init" branch in "X64/MpFuncs.nasm" correctly considers a
64-bit stack start: the "MP_CPU_EXCHANGE_INFO.StackStart" field has type
UINTN, and the code uses QWORD addition and movement to set RSP from it.
Adapt the "GetApicId" branch of "X64/MpFuncs.nasm":
- change the type of "CPU_INFO_IN_HOB.ApTopOfStack" to UINT64,
- remove the explicit truncation to UINT32 in InitializeApData(),
- update the "GetNextProcNumber" iteration size to the new size of
"CPU_INFO_IN_HOB",
- set RSP with a QWORD movement from "CPU_INFO_IN_HOB.ApTopOfStack".
Because the same CPU_INFO_IN_HOB structure is used by "Ia32/MpFuncs.nasm",
we have to update the "GetNextProcNumber" iteration size there as well.
The ESP setting can be preserved as a DWORD movement from the original
offset (decimal 12), since our integers are little endian.

Currently, MpInitLib will program AP stack in dynamic address. Each processor
will calculate its stack address by adding stack size based on the last stack
address. That means AP may have the different stack address everytime it is
wakeup by INIT-SIPI-SIPI.
When all APs have wakeup to execute AP task, each each has been assigned one
stack address. Once the timeout happened on some of APs, BSP will send INIT-
SIPI-SIPI to wake up APs. We need to re-assign stack for APs. Based on the
current implementation, we might assign one stack address used by other APs.
It will cause the unexpected stack overlapped issue.
This fix changed the stack assignment policy. We will record the stack address
assigned to AP at first time AP wakeup. When AP failed on AP task, BSP could
reassigned the same stack for it.
Getting initial APIC ID in assembly code could help AP to get saved its stack
address.

SMRR range size and alignment should follow the rules like MTRR:
a. The minimum range size is 4 KBytes and the base address of the
range must be on at least a 4-KByte boundary.
b. For ranges greater than 4 KBytes, each range must be of length
2^n and its base address must be aligned on a 2^n boundary, where
n is a value equal to or greater than 12. The base-address
alignment value cannot be less than its length.
Thus, it could meet "Address_Within_Range AND PhysMask = PhysBase

Use the library functions for shift operations in BaseLib for a 64-bit integer where the code is shared for 32-bit and 64-bit.
