Re: The 3G (or nG) Kernel Memory Space Offset

Since it's all just virtual addresses, is the TLB flush really that muchdifferent when kernelspace runs from (virtual) 0x00000000-0x3FFFFFFF ratherthan (virtual)0xC000000-0xFFFFFFFF?

If kernel and userspace are disjoint, they can be in the same addressspace, so there's no need for a TLB flush at all.
