PG_dirty bit

[pnilesh@in.ibm.com]

kerenl 2.2.5-15

In try_to_swap_out () after the page is found to be dirty it is swapped
out.
One of the comments there says that it should just set the dirty bit in
page_map and drop pte .
But in the code I could not find anywhere PG_dirty flag being set in
page_map.
Or there is some magic involved ?

If I have missed out something please enlighten me.
