(y,n) Sadly, x86_64 also has 4kB PAGE_SIZE like i386 (for compatibility reason or whatever). I'd always hoped for 8kB+ PAGE_SIZE when we got to 64-bit but it seems this will never happen. > Anyone do this before and had any kind of success? You need Alpha, PPC, ia64, mips, arm?, or possibly other non-*86 arch to have large PAGE_SIZE, or fix the VM to support larger PAGE_SIZE than the hardware.
