Move register and other definitions out of the
include/asm-arm/arch-s3c2410 into the the arch
directories of include/asm-arm/plat-s3c24xx and
include/asm-arm/plat-s3c.

This move is in preperation of the merging of
s3c2400 and s3c6400.

BUGs for both slab and slub, and slob never supported them
either.

This rips out support for the dtor pointer from kmem_cache_create()
completely and fixes up every single callsite in the kernel (there were
about 224, not including the slab allocator definitions themselves,
or the documentation references).

Now that ide-floppy supports SG_IO we can add support for SCSI ioctls
(except deprecated SCSI_IOCTL_SEND_COMMAND and legacy CDROM_SEND_PACKET
ones - we can add them later iff really needed).

While at it remove handling of CDROMEJECT and CDROMCLOSETRAY ioctls from
generic_ide_ioctl():

- This prevents ide-{disk,tape,scsi} device drivers from obtaining
  REQ_TYPE_BLOCK_PC type requests which are currently unsupported by
  these drivers and which are potentially harmful (as reported by Andrew).

- There is no functionality loss since aforementioned ioctls will now be
  handled by idefloppy_ioctl()->scsi_cmd_ioctl() (for devices using
  ide-floppy driver) and by idecd_ioctl->cdrom_ioctl()->scsi_cmd_ioctl()
  (for devices using ide-cd driver).

The driver used to depend on BIOS settings for deciding whether it is OK
to use DMA.  However it seems that BIOS doesn't always handle all cases
correctly so just let IDE core to decide about this.  It should be a safe
thing to do now, after the driver went through heavy bugfixing.

* Move code responsible for programming chipset for PIO mode from
  svwks_tune_chipset() to svwks_tune_pio().  Don't tune PIO when tuning
  DMA (this is no longer needed since ->autotune is always set now).

* Add missing ide_get_best_pio_mode() call to sil_tuneproc() so
  "pio" == 255 (autotune) is handled correctly (previously PIO0 was used)
  and "pio" values > 4 && < 255 are filtered to PIO4 (instead of PIO0).

* Add code limiting maximum PIO mode according to the pair device capabilities

* Convert users of config_siimage_chipset_for_pio() to use sil_tune_pio() and
