Hi, guys,
   Understanding VM:
    The first pointers to pg0 and pg1 are placed to cover the region 1-9MiB and 
the second pointers to pg0 and pg1 are 
placed at PAGE_OFFSET+1MiB.
   ULK2:
   Therefore, the kernel must create a mapping from both the linear addresses 
0x00000000 through 0x007fffff and the linear 
addresses 0xc0000000 through 0xc07fffff into the physical addresses 0x00000000 
through 0x007fffff.
   一个说是1-9M, 一个说是0-8M, 谁是对的?昏......
Best Regards
  Ouyang Kai
