You beat me on that aspect :) PS: Once there was a patch to create 4:4 VM split written by Ingo Molnar. It does maximize address space at the expense of full TLB flush on every context switch. AFAIK it once included in Fedora core 2 or 3, but dropped afterward since it puts more negative impacts rather than positive enhancement (in virtual memory management point of view) -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
