Hello everybody,
     While running through source of 2.4 kernel, in head.S, I found the 
line
86 :   movl $pg0-__PAGE_OFFSET,%edi

    I am not getting, at this point there is no virtual address & $pg0 
itself contains physical address of first page table, then why to 
subtract 3GB from the physical address?
      Thanx in anticipation.

 -  Amey
