[PATCH 00/18] ide: warm-plug support for IDE devices and other goodies

[Bartlomiej Zolnierkiewicz]

- couple of fixes and preparatory patches

- rework of PowerMac media-bay support ([un]register IDE devices instead of
  [un]registering IDE interface) [ it is the main reason for spamming PPC ML ]

- IDE warm-plug support (though it is still experimental it should work fine,
  unlike the older method), to warm-plug devices on a port 'idex':

  # echo -n "1" > /sys/class/ide_port/idex/delete_devices

  unplug old device(s) and plug new device(s)

  # echo -n "1" > /sys/class/ide_port/idex/scan

  done

- ability to add new interfaces for ide-generic host driver through
  /sys/class/ide_generic/add, i.e.

  echo -n "0x168:0x36e:10" > /sys/class/ide_generic/add

- because of the above changes some obsoleted/broken code can be removed
  (thus the total effect of the patch series is -100 LOC)
