Current implementation uses following two methods
EnableNullDetection()
DisableNullDetection()
to enable/disable page 0. These two methods will check PCD
PcdNullPointerDetectionPropertyMask to know if the page 0 is disabled or not.
This is due to the fact that old GCD service doesn't provide paging related
attributes of memory block. Since this issue has been fixed, GCD services
can be used to determine the paging status of page 0. This is also make it
possible to just use a new macro
ACCESS_PAGE0_CODE(
<code accessing page 0>
);
to replace above methods to do the same job, which also makes code more
readability.
