Thanx. vtophys() was indeed what I was looking for.
I have one more question. Now, that I have the physical address (which is
locked, pinned, protected from swapping out), I need to write data to this.
I can't use normal copy functions, can I? Cause they expect the address to
be the virtual address.
Thanx,
Pavan Balaji,
