Subject: [git patches] IDE fixes
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
Please pull from:
master.kernel.org:/pub/scm/linux/kernel/git/bart/ide-2.6.git/
