linux page table

[Xin Tong]

When a process is created in Linux, corresponding page table is
implemented. In the current x86 linux, the page table is a multi-level
page table and CR3 points to the first level of the page table.  I
have 2 questions.

1. is the value in CR3 virtual address or physical address ?
2. can the address of the first level of the page table during a
process's lifetime change ?
3. can two different processes have their CR3 being the same value
even though they have different first level page tables ?

Thanks
