Add comment for the use of mOnGuarding > e. Change name of function InitializePageTableLib to > InitializePageTableGlobals > f. Add code in 32-bit code to bypass setting page table to read-only > g. Coding style clean-up > This feature makes use of paging mechanism to add a hidden (not present) page just before and after the allocated memory block. If the code tries to access memory outside of the allocated part, page fault exception will be triggered. This feature is disabled by default and is not recommended to enable it in production build of BIOS.
