V2 changes:
Update the commit message and comments in the code.
When waking vector buffer allocated by CpuDxe is tested by MemTest86
in MP mode, an error is reported because the same range of memory is
modified by both CpuDxe driver and MemTest86.
The waking vector buffer is not expected to be tested by MemTest86 if
it is allocated out because MemTest86 only tests free memory. But
current CpuDxe driver "borrows" buffer instead of allocate buffer for
waking vector buffer (through allocate & free to get the buffer
pointer, backup the buffer data before using it and restore it after
using). With this implementation, if the buffer borrowed is not used
by any other drivers, MemTest86 tool will treat it as free memory
and test it.
In order to fix the above issue, CpuDxe changes to allocate the
buffer below 1M instead of borrowing it. But directly allocating
memory below 1MB causes LegacyBios driver fails to start. LegacyBios
driver allocates memory range from
"0xA0000 - PcdEbdaReservedMemorySize" to 0xA0000 as Ebda Reserved
Memory. The minimum value for "0xA0000 - PcdEbdaReservedMemorySize"
is 0x88000. If LegacyBios driver allocate this range failed, it
asserts.
LegacyBios also reserves range from 0x60000 to
"0x60000 + PcdOpromReservedMemorySize", it will be used as Oprom
Reserve Memory. The maximum value for "0x60000 +
PcdOpromReservedMemorySize" is 0x88000. LegacyBios driver tries to
allocate these range page(4K size) by page. It just reports warning
message if some pages are already allocated by others.
Base on above investigation, one page in range 0x60000 ~ 0x88000 can
be used as the waking vector buffer.
LegacyBios driver only reports warning when page allocation in range
[0x60000, 0x88000) fails. This library is consumed by CpuDxe driver
to produce CPU Arch protocol. LagacyBios driver depends on CPU Arch
protocol which guarantees below allocation runs earlier than
LegacyBios driver.

Index is initialized to MAX_UINT16 as default failure value, which
is what the ASSERT is supposed to test for. The ASSERT condition
however can never return FALSE for INT16 != int, as due to
Integer Promotion[1], Index is converted to int, which can never
result in -1.
Furthermore, Index is used as a for loop index variable inbetween its
initialization and the ASSERT, so the value is unconditionally
overwritten too.
Fix the ASSERT check to compare Index to its upper boundary, which it
will be equal to if the loop was not broken out of on success.

Base on UEFI spec requirement, StartAllAPs function should not use the APs which has been disabled before. This patch just change current code to follow this rule.
V3 changes:
Only called by StartUpAllAps, WakeUpAp will not wake up the disabled APs, in other cases also need to include the disabled APs, such as CpuDxe driver start up and ChangeApLoopCallback function.
WakeUpAP() is called with (Broadcast && WakeUpDisabledAps) from MpInitLibInitialize(), CollectProcessorCount() and MpInitChangeApLoopCallback() only. The first two run before the PPI or Protocol user has a chance to disable any APs. The last one runs in response to the ExitBootServices and LegacyBoot events, after which the MP protocol is unusable. For this reason, it doesn't matter that an originally disabled AP's state is not restored to Disabled, when
WakeUpAP() is called with (Broadcast && WakeUpDisabledAps).

if PcdDxeNxMemoryProtectionPolicy is enabled for EfiReservedMemoryType
of memory, #PF will be triggered for each APs after ExitBootServices
in SCRT test. The root cause is that AP wakeup code executed at that
time is stored in memory of type EfiReservedMemoryType (referenced by
global mReservedApLoopFunc), which is marked as non-executable.
This patch fixes this issue by setting memory of mReservedApLoopFunc to
be executable immediately after allocation.

If PcdDxeNxMemoryProtectionPolicy is set to enable protection for memory
of EfiBootServicesCode, EfiConventionalMemory, the BIOS will hang at a page
fault exception during MP initialization.
The root cause is that the AP wake up buffer, which is below 1MB and used
to hold both AP init code and data, is type of EfiConventionalMemory (not
really allocated because of potential conflict with legacy code), and is
marked as non-executable. During the transition from real address mode
to long mode, the AP init code has to enable paging which will then cause
itself a page fault exception because it's just running in non-executable
memory.
The solution is splitting AP wake up buffer into two part: lower part is
still below 1MB and shared with legacy system, higher part is really
allocated memory of BootServicesCode type. The init code in the memory
below 1MB will not enable paging but just switch to protected mode and
jump to higher memory, in which the init code will enable paging and
switch to long mode.

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.
