/** @file

Polymorphic functions that are called from both the privileged driver (i.e.,
|
|
the DXE_SMM variable module) and the non-privileged drivers (i.e., one or
|
|
both of the DXE_RUNTIME variable modules).
|
|
|
|
Each of these functions has two implementations, appropriate for privileged
|
|
vs. non-privileged driver code.
