Virtual Memory Initialization

[salekinsirajus]

• The original Xinu memory initialization does not allow the whole 4GB address space to be available for paging. Replace the original meminit.c and i386.c files in the system folder with the ones attached, which fix the problem.

• After paging is enabled, all memory accesses are through virtual addresses. Therefore, you need to map the static segments (TEXT, DATA, etc.) into the virtual memory space of each process.
