Analysis of the current usage patterns revealed that this parameter
should consistently set to TRUE.
Specifically, the parameter was found to be False in the following
scenarios:
1. During the initial volatile register setup for the first AP wake-up
in both the PEI and DXE phases. In these instances, the volatile
registers are pre-initialized in MpInitLibInitialize(),
and manually setting them to zero does not require altering the DR
state.
2. When switching the BSP, the new BSP does not synchronize the DR.
This behavior is now adjusted to ensure the DR state is synchronized,
aligning with a more logical and expected behavior when transitioning
BSP roles.

In previoud commit, we remove the ApInitReconfig status. Now there
are only two status ApInitConfig and ApInitDone.
Only the very first waking up AP needs to set ApInitConfig status.
Therefore, if this is not the first wake up, set ApInitDone status
Signed-off-by: Zhiguang Liu <zhiguang.liu@intel.com>
ApInitReconfig status is used to indicate that when AP wakes up, AP
need to restore volatile registers from BSP and use InitSipiSipi. Since
we handle the volatile registers well, we can use WakeUpByInitSipiSipi
flag to replace ApInitReconfig. Avoid using ApInitReconfig can simplify
code.

When enable stack guard, APs needs separate GDTs.
In current code, APs will lose their separate GDTs when AP get disabled
and later re-enabled. This is because when re-enabling AP, AP restores
volatile registers from BSP.
This patch updates the AP management to ensure that each AP saves and
restores its own set of volatile registers to solve this issue.
Key changes include:
- APs now maintain their own volatile register space, eliminating
dependency on the BSP's register state.
- Special handling is implemented for the first AP wake-up during the
PEI and DXE phases, where the volatile registers are synchronized from
the BSP.
- When switching BSP, remove manual handling the global variable
CpuMpData->CpuData[Index].VolatileRegisters. The manually handling
in previous code is because, old BSP may not save volatile registers
after the AP procedure and new BSP's VolatileRegisters buffer may be
used by other APs. Now, since AP always save/restore volatile registers
from their own buffer, no need to do the special handling.

BSP should save and sync to AP the init timer count instead of
current timer count.
Also, BSP can check the init timer count to know if the local apic
timer is enabled. Only sync the setting when it is enabled.
Signed-off-by: Zhiguang Liu <zhiguang.liu@intel.com>
This update ensures the consistency of Local APIC timer settings across
all processors when a BSP switch occurs.
The Local APIC timer is utilized in two distinct scenarios:
1. As a delay mechanism within the timer library.
2. To generate periodic timer interrupts during the DXE phase.
For scenario 1, APs can simply inherit the initial settings from the
BSP. Even the local APIC timer setting is changed by BSP later, AP
can still use the old setting. Therefore, the code to save the Local
APIC timer can be moved to MpInitLibInitialize().
For scenario 2, because normal AP doesn't enable timer interrupt, we
only need to care SwitchBsp case. It is crucial that the periodic
timer interrupts remain operational after BSP is switched. To achieve
this, the Local APIC timer settings on old BSP are now preserved and
synced to new BSP.

This reverts commit ae59b8ba41.
The commit ae59b8ba41 was added to modify the GenSmmPageTable()
to map SMRAM in 4K page granularity. It was to urgently fix a
smm hang issue by avoiding page split in paging structures that
covers SMRAM range when SMI happens. But finally the smm hang
issue was root caused and fixed by commit 839bd17973.
Meanwhile a smm page table creation related issue was introduced
by commit ae59b8ba41:
In the function GenSmmPageTable(), the paging level for the range
outside SMRAM is depend on the Input parameter PagingMode. However,
the paging level for SMRAM range is depend on m5LevelPagingNeeded.
If the two paging levels are different, then the smm page table is
created incorrectly.
So let's revert the commit "UefiCpuPkg/PiSmmCpuDxeSmm:Map SMRAM

Platforms today may use this PCD as a dynamic PCD as that is an
allowed type in its PCD declaration. From `ArmPkg.dec`:
[PcdsFixedAtBuild.common, PcdsDynamic.common, PcdsPatchableInModule.common]
gArmTokenSpaceGuid.PcdSystemMemorySize|0|UINT64|0x0000002A
This library causes a build error if it used as a dynamic PCD since
it places the PCD in a `[FixedPcd]` section in the INF.
Other libraries do set the PCD and depend on the dynamic PCD behavior.
Since this library accesses the PCD with `PcdGet64 ()` which is
compatible with FixedAtBuild PCDs, this change moves the PCD out an
explicit `[FixedPcd]` section to resolve the following build error:
```
INFO - : error 3000: Building modules from source INFs, following

It must be corrected to use only one access

Introduce a driver that allows users to disable the EFI Memory Attribute
protocol through an HII setup option, in order to work around a broken

which incorrectly invokes the protocol and results in a Synchronous

Default is enabled, which can also be overridden at build time by
changing `gEmbeddedTokenSpaceGuid.PcdMemoryAttributeEnabledDefault`.
It is only applicable to ARM64 and there isn't any other technical
reason for disabling this security feature.
