Re: calculating physical memory address

I need to know which function translates the linear logical address (e.g. 
0x08048000) to the memory address, where the data is physically stored.
(And vice versa.)

I use the book "Understanding the Linux Kernel 2nd Edition" for my question,
there they say: how the calculation of the physical memory address is done. 
[source: page 56] "Figure 2-4. Translating a logical address"

To be more precise:
	in task_struct is mm_struct.
	mm_struct has: 
	"unsigned long start_code, end_code, start_data, end_data;".

I need to know where start_code and end_code is saved in the physical memory.

thanks in advice,
