The stack size in the entrypoint (ie: $ARCH/ModuleEntryPoint.S) is calculated such as
StackSize = PrimaryCoreStack + (core_count - 1) * SecondaryCoreStack
While we were declaring the stacksize into the stack hob as:
StackSize = PrimaryCoreStack + (cluster * 8) * SecondaryCoreStack
If the number of cluster (ie: PcdClusterCount) were not defined correctly then
the stack size declaration were not correct.
It could cause stack corruption if the allocator allocates memory in this range.

If EditHIInputStr() is called, say with a MaxCmdLine of 2, the user is
currently allowed to enter 2 characters.
If the second character is a carriage return/line feed, this is
substituted with a NULL and the function returns.
If the second character is a regular character, the loop terminated and
the function returns. However, the buffer has not been NULL terminated.
This patch prevents the user from entering a regular character as the
final character and ensures that the only way out of the input is by
pressing ESC or ENTER (or equivalent).

Several assembler macros use a loop at the label "dead" to trap an error.
This is difficult to debug as there is no indication of how one arrived at the loop.
This change replaces dead with distinct loops locally in the macro,
which means the cause of the hang is detectable to the debugger.

This patch adds an EDK2_ARMVE_SUPPORT_QEMU macro that can be defined at build
time to build an image that supports QEMU. The default build is unchanged and
builds the RTSM configuration.
QEMU only models fixed size blocks within a flash device, and the RTSM
configuration stores EFI variables in the smaller boot blocks of the
flash. When built for QEMU the larger blocks are used that QEMU properly
emulates.
