Remove pmdisk from kernel

[Pavel Machek]

Hi!

This removes pmdisk from kernel. Nobody maintains it and swsusp
provides same functionality (and more, pmdisk is actually fork of
swsusp code).

3 files need to be removed by hand, I did not want to obscure patch by
removing them like that (and you probably have slightly different
pmdisk.c, anyway).

rm arch/i386/power/pmdisk.S
rm kernel/power/disk.c
rm kernel/power/pmdisk.c

								Pavel

PS: Alternatively, I'm wiling to kill swsusp, rename pmdisk to "swap
suspend", and submit patches to fix it. Its going to be slightly more
complicated, through...

-config PM_DISK
-	bool "Suspend-to-Disk Support"
-	depends on PM && SWAP
-	---help---
-	  Suspend-to-disk is a power management state in which the contents
-	  of memory are stored on disk and the entire system is shut down or
-	  put into a low-power state (e.g. ACPI S4). When the computer is 
-	  turned back on, the stored image is loaded from disk and execution
-	  resumes from where it left off before suspending. 
-
-	  This config option enables the core infrastructure necessary to 
-	  perform the suspend and resume transition. 
-
-	  Currently, this suspend-to-disk implementation is based on a forked
-	  version of the swsusp code base. As such, it's still experimental,
-	  and still relies on CONFIG_SWAP. 
-
-	  More information can be found in Documentation/power/.
-
-	  If unsure, Say N.

-config PM_DISK_PARTITION
-	string "Default resume partition"
-	depends on PM_DISK
-	default ""
-	---help---
-	  The default resume partition is the partition that the pmdisk suspend-
-	  to-disk implementation will look for a suspended disk image. 
-
-	  The partition specified here will be different for almost every user. 
-	  It should be a valid swap partition (at least for now) that is turned
-	  on before suspending. 
-
-	  The partition specified can be overridden by specifying:
-
-		pmdisk=/dev/<other device> 
-
-	  which will set the resume partition to the device specified. 
-
-	  One may also do: 
-
-		pmdisk=off
-
-	  to inform the kernel not to perform a resume transition. 
-
-	  Note there is currently not a way to specify which device to save the
-	  suspended image to. It will simply pick the first available swap 
-	  device.
