Get_free_page

[DVSM]

Hi, I want to know whether get_free_page returns a physical address or a
virtual address which has to converted to a physical address. Another
thing does the kernel use virtual addresses i.e does it go through it's
page tables or it directly accesses the memory. Is it not the case that in
kernel space physical and virtual addresses are same.
I am using 2.0.33
Thanks in advance.
