-  This option is available only if the kernel has been compiled with

-dynamically whether to actually use ST-RAM as swap space. (Currently,
-the fraction of ST-RAM must be less or equal 1/3 of total memory to
-enable this swapping.) You can override the kernel's decision by
-specifying this option. 1 for <do_swap> means always enable the swap,
-even if you have less alternate RAM. 0 stands for never swap to
-ST-RAM, even if it's small enough compared to the rest of memory.

-  If ST-RAM swapping is enabled, the kernel usually uses all free

-	---help---
-	  Some Atari 68k machines (including the 520STF and 1020STE) divide
-	  their addressable memory into ST and TT sections.  The TT section
-	  (up to 512MB) is the main memory; the ST section (up to 4MB) is
-	  accessible to the built-in graphics board, runs slower, and is
-	  present mainly for backward compatibility with older machines.
-
-	  This enables support for using (parts of) ST-RAM as swap space,
-	  instead of as normal system memory. This can first enhance system
-	  performance if you have lots of alternate RAM (compared to the size
-	  of ST-RAM), because executable code always will reside in faster
-	  memory. ST-RAM will remain as ultra-fast swap space. On the other
-	  hand, it allows much improved dynamic allocations of ST-RAM buffers
-	  for device driver modules (e.g. floppy, ACSI, SLM printer, DMA
-	  sound). The probability that such allocations at module load time

- * New Nov 1997: Use ST-RAM as swap space!
- *
- * In the past, there were often problems with modules that require ST-RAM
- * buffers. Such drivers have to use __get_dma_pages(), which unfortunately
- * often isn't very successful in allocating more than 1 page :-( [1] The net
- * result was that most of the time you couldn't insmod such modules (ataflop,
- * ACSI, SCSI on Falcon, Atari internal framebuffer, not to speak of acsi_slm,
- * which needs a 1 MB buffer... :-).
- *
- * To overcome this limitation, ST-RAM can now be turned into a very
- * high-speed swap space. If a request for an ST-RAM buffer comes, the kernel
- * now tries to unswap some pages on that swap device to make some free (and
- * contiguous) space. This works much better in comparison to
- * __get_dma_pages(), since used swap pages can be selectively freed by either
- * moving them to somewhere else in swap space, or by reading them back into
- * system memory. Ok, there operation of unswapping isn't really cheap (for
- * each page, one has to go through the page tables of all processes), but it
- * doesn't happen that often (only when allocation ST-RAM, i.e. when loading a
- * module that needs ST-RAM). But it at least makes it possible to load such
- * modules!
- *
- * It could also be that overall system performance increases a bit due to
- * ST-RAM swapping, since slow ST-RAM isn't used anymore for holding data or
- * executing code in. It's then just a (very fast, compared to disk) back
- * storage for not-so-often needed data. (But this effect must be compared
- * with the loss of total memory...) Don't know if the effect is already
- * visible on a TT, where the speed difference between ST- and TT-RAM isn't
- * that dramatic, but it should on machines where TT-RAM is really much faster
- * (e.g. Afterburner).
- *
- *   [1]: __get_free_pages() does a fine job if you only want one page, but if
- * you want more (contiguous) pages, it can give you such a block only if
- * there's already a free one. The algorithm can't try to free buffers or swap
- * out something in order to make more free space, since all that page-freeing
- * mechanisms work "target-less", i.e. they just free something, but not in a
- * specific place. I.e., __get_free_pages() can't do anything to free
- * *adjacent* pages :-( This situation becomes even worse for DMA memory,
- * since the freeing algorithms are also blind to DMA capability of pages.
