[git patches] IDE fixes

[Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>]

Hi,

We merged _a_lot_ of IDE patches for 2.6.25 so no wonder that a few bugs
showed up (yes, mostly brown paper ones of mine :).  This update should
put it under control again (there are two more open regression bugreports
left and they are going to be addressed as soon as we have more data).

- fix nasty bug in handling of flush requests (extra thanks to Sebastian
  Siewior / James Bottomley / Christoph Hellwig for help with fixing it)

- fix ide_port_init() regression (spotted by Atsushi Nemoto)

- fix build of bast-ide of gayle host drivers (Adrian Bunk)

- fixes for Palm BK3710 support (Sergei Shtylyov and me)

- fix another possible ide-cd panic (Kiyoshi Ueda)

- other minor fixes
