[PATCH] swsusp & acpi_sleep: configuration issues

This moves CONFIG_SOFTWARE_SUSPEND where it belongs, and makes
ACPI_SLEEP depend on it to prevent compile problems.

Enable the possibilty of suspendig machine. It doesn't need APM.
You may suspend your machine by 'swsusp' or 'shutdown -z <time>'
(patch for sysvinit needed).
It creates an image which is saved in your active swaps. By the next
booting the, pass 'resume=/path/to/your/swap/file' and kernel will
detect the saved image, restore the memory from
it and then it continues to run as before you've suspended.
If you don't want the previous state to continue use the 'noresume'
kernel option. However note that your partitions will be fsck'd and
you must re-mkswap your swap partitions/files.
Right now you may boot without resuming and then later resume but
in meantime you cannot use those swap partitions/files which were
involved in suspending. Also in this case there is a risk that buffers
on disk won't match with saved ones.
SMP is supported ``as-is''. There's a code for it but doesn't work.
There have been problems reported relating SCSI.
This option is about getting stable. However there is still some
absence of features.
For more information take a look at Documentation/swsusp.txt.
