I'm guessing here, but I'm guessing that you can take:
[bill@bilbo bill]$ head -2 /proc/1223/maps
08048000-0804d000 r-xp 00000000 09:01 2235926    /bin/login
0804d000-0804e000 rw-p 00004000 09:01 2235926    /bin/login

I'm willing to bet that if /bin/login were a culprit that the block in
swap would correlate with the mapped page in maps.

I'm assuming/hoping that the physical address in the swap partition
directly maps to the numbers in /proc/<pid>/maps but I'm not sure, if not
I'm guessing a few kernel tweaks would be necessary to find the mapping.
