[PATCH] Atari ST-RAM swap update

Jeff removed the swap_device member from struct swap_info_struct
(http://www.uwsg.iu.edu/hypermail/linux/kernel/0202.1/0258.html)
but it is still used in the m68k arch for the ST-RAM. The below
should remove it.

Frankly, I didn't try compiling... My original intent was to move the
swap_list definition from swap.h to mm/swapfile.c, but m68k still
uses it here :( so perhaps this isn't possible. And I just happened to
stumble upon this.
