Never. If the kernel virtual address is 0x80000000+off with 0 <= off <=
0x1fffffff (aka kseg0, defined by bits 31..29), the corresponding physical
address is always 0+off, no matter what PHYS_OFFSET you invent. Physical
memory at 0x20000000 is not reachable from kesg0/1.



I already answered that was bullshit and I took drugs before writing this...

thanks
