-/**
-  This API provides a method for a CPU to allocate a specific region for
-  storing page tables.
-
-  This API can be called more once to allocate memory for page tables.
-
-  Allocates the number of 4KB pages of type EfiRuntimeServicesData and returns
-  a pointer to the allocated buffer.  The buffer returned is aligned on a 4KB
-  boundary.  If Pages is 0, then NULL is returned.  If there is not enough
-  memory remaining to satisfy the request, then NULL is returned.
-
-  This function can also return NULL if there is no preference on where the
-  page tables are allocated in SMRAM.
-
-  @param  Pages                 The number of 4 KB pages to allocate.
-
-  @return A pointer to the allocated buffer for page tables.
-  @retval NULL      Fail to allocate a specific region for storing page tables,
-                    Or there is no preference on where the page tables are
-                    allocated in SMRAM.
