the upper 256 entries of the page table (ie the pgds used for mapping 3g to 4g) are same for all the processes....ie the same entries are copied in every processes page tables when it is created.
Isn't that suboptimal? I mean duplicating 256 page table entries for every process? Shouldn't processes be sharing these 256 entries?
