The background operations of the L2x0 cache controllers are aborted if
another operation is issued on the same or different core. This patch

Slab destructors were no longer supported after Christoph's
c59def9f change. They've been
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.

Thanks for bugreport and testing the patch goes out to Sven Niedner.

* Always set ->autotune so PIO gets correctly auto-tuned (previously
  ->autotune was only set when ->dma_base wasn't available, however
  ->ide_dma_check()/->speedproc() was always trying to tune PIO when

* 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).

* Handle PIO modes early in svwks_tune_chipset() so DMA configuration
  registers don't get cleared when programming PIO mode.

Various old IDE drivers go mapping ROM devices for no apparent reason and
without using the ROM mapping API we now have. They don't actually use
the ROM they map and the new libata drivers are happy without it being
mapped so rather than port them lets just junk it for the next -rc1.
