According to section 3.2 of the [GHCI] spec, if the return status
of MapGPA is "TDG.VP.VMCALL_RETRY", TD must retry this operation
for the pages in the region starting at the GPA specified in R11.
Currently, TDVF has not handled the retry results and always clears
the R11 on unsuccessful return status. For this, the TdVmcall needs
to output the value of R11 on unsuccessful return status to handle
the retry results of MapGPA.

Bugzilla: 3706 'Code First - MADT GICC new flags'
On ARM systems physical CPU hotplug is not supported.
All CPUs are considered present and this is true
throughout the system uptime.
The ECR 2285 introduces a new 'online-capable' flag
in the GICC structure flags in ACPI 6.5, to signal
firmware policy (CPU is not enabled but it can be
enabled and onlined). This enables OSPM to support
virtual CPU hotplug (on virtual platforms for
instance).
This ECR also updates the MADT table revision to 6
to reflect the ACPI 6.5 changes. Therefore, update
the MADT table revision to match the value as
specified in ACPI 6.5.

This commit is code optimization to InternalAllocateAlignedPages of
SmmMemoryAllocationLib which can reduce free memory fragments. Also
it can reduce one pre-allocation page.
Let's take a simple example:
The expected pages size is 8KB, Alignment value is 8KB.
In original InternalAllocateAlignedPages(), the first step is to
allocate 4 pages and then find the first 8KB-aligned address in
allocated 4 pages. If the upper limit address of allocated 4 pages
is already 8KB aligned, then the allocated 4 pages contains two
8KB-aligned 8KB ranges. The lower 2 pages will be selected and
removed from free pages. Then the higher 2 pages will be free.
Since the whole memory allocation is from high address to low
address, then the higher 2 pages cann't be merged with other free
pages, causing the free memory fragments.
However, when only allocate 3(2+2-1) pages, we can avoid the free
memory fragments in specific case. Also 3 pages must contain a
8KB-aligned 8KB range, which meets the requirement. If the upper
limit address of allocated 3 pages is 8KB-aligned, then the higher
2 pages range of allocated 3 pages is 8KB-aligned and will be
selected and removed from free pages. The remaining lower one page
of allocated 3 pages will be free and merged with left lower free
memory. This can reduce free memory fragments in smm.
