[PATCH] mm: m68k kill stram swap
Please, please now delete the Atari CONFIG_STRAM_SWAP code. It may be excellent and ingenious code, but its reference to swap_vfsmnt betrays that it hasn't been built since 2.5.1 (four years old come December), it's delving deep into matters which are the preserve of core mm code, its only purpose is to give the more conscientious mm guys an anxiety attack from time to time; yet we keep on breaking it more and more. If you want to use RAM for swap, then if the MTD driver does not already provide just what you need, I'm sure David could be persuaded to add the extra. But you'd also like to be able to allocate extents of that swap for other use: we can give you a core interface for that if you need. But unbuilt for four years suggests to me that there's no need at all. I cannot swear the patch below won't break your build, but believe so.

669 This option is available only if the kernel has been compiled with
670CONFIG_STRAM_SWAP enabled. Normally, the kernel then determines
671dynamically whether to actually use ST-RAM as swap space. (Currently,
672the fraction of ST-RAM must be less or equal 1/3 of total memory to
673enable this swapping.) You can override the kernel's decision by
674specifying this option. 1 for <do_swap> means always enable the swap,
675even if you have less alternate RAM. 0 stands for never swap to
676ST-RAM, even if it's small enough compared to the rest of memory.
677
678 If ST-RAM swapping is enabled, the kernel usually uses all free
679ST-RAM as swap "device". If the kernel resides in ST-RAM, the region
680allocated by it is obviously never used for swapping :-) You can also
681limit this amount by specifying the second parameter, <max_swap>, if
682you want to use parts of ST-RAM as normal system memory. <max_swap> is
683in kBytes and the number should be a multiple of 4 (otherwise: rounded
684down).
