Swap

MEM_swap_init ()

void        MEM_swap_init                   (void);

Gets things ready to be able to swap memory in and out.

MEM_swapout_page ()

void        MEM_swapout_page                (gint pid,
                                             gint page);

Writes page from Proces' pid virtual memory address space from memory into a free block in the swap device.

MEM_swapin_page ()

void        MEM_swapin_page                 (gint pid,
                                             gint page,
                                             guint32 set_flags);

Reads page from Proces' pid virtual memory address space into memory from the swap device

If the page has never been swapped out we will suppose it is in the first free swap block and request an IO access to it.

If the page is already swaping in then we will take note of set_flags and let it be.
