Jeff Fan c6b0feb396 UefiCpuPkg/MpInitLib: Check APIC mode change around AP function
If APIC ID values are changed during AP functions execution, we need to update
new APIC ID values in local data structure accordingly.

But if APIC mode change happened during AP function execution, we do not support
APIC ID value changed.

Jeff Fan 6661abb695 UefiCpuPkg/CpuCommonFeaturesLib: Support X2APIC enable
Current X2APIC is enabled in MpInitLib (used by CpuMpPei and CpuDxe) to follow
SDM suggestion. That means we only enable X2APIC if we found there are any
initial CPU ID value >= 255.

This patch is to provide one chance for platform to enable X2APIC even there is
no any initial CPU ID value >= 255.

Michael Kinney 3b2928b469 UefiCpuPkg/MpInitLib: Fix X64 XCODE5/NASM compatibility issues
https://bugzilla.tianocore.org/show_bug.cgi?id=565

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().

NASM requires read-only data sections to use the section

The build failure from use of .rdata is seen when using
the XCODE5 tool chain.

Section "7.8.1 macho extensions to the SECTION Directive"

Ruiyu Ni 3654c4623c UefiCpuPkg/MtrrLib: Don't report OutOfResource when MTRR is enough
The MTRR calculation algorithm contains a bug that when left
subtraction cannot produce better MTRR solution, it forgets
to restore the BaseAddress/Length so that MtrrLibGetMtrrNumber()

MTRR is enough.

The current CPU_REGISTER_TABLE_ENTRY structure only defined UINT32 Index to

actually. But for MMIO address, UINT32 limits MMIO address exceeds 4GB.

This update on CPU_REGISTER_TABLE_ENTRY is to add additional UINT32 field
HighIndex to indicate the high 32bit MMIO address and original Index still
indicate the low 32bit MMIO address.

This update makes use of original padding space between ValidBitLength and
Value to add HighIndex.

Hao Wu 8491e302e1 UefiCpuPkg: Refine casting expression result to bigger size
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'.

Jeff Fan b9d56d0b93 UefiCpuPkg/ExceptionHandlerAsm.S: Fix code length issue with GCC 5.4
X64\ExceptionHandlerAsm.S define MARCO to set up 32 IDT entries header.
It assume GCC compiler will generate the same code length on the following
instrction for each IDT entry.
  jmp    ASM_PFX(CommonInterruptEntry)

It works with GCC 4.x. However, GCC 5.4 will generate different code size of IDT
entry code per the offset value from CommonInterruptEntry address. We should use
DB to make sure each IDT entry header has the same size whatever compiler
version.

.ASM and .nasm used the different solution and do not have this issue.
