[PATCH] 2.5.8 IDE 37
- Don't abuse the sense field for passing failed packet_commands in struct
packet_command use a new field instead.
- Apply minor bits forwarded by Dave Jones to me.
- Fix ide_raw_taskfile() to flag the ar used there to be no subject of free_req
list management. This solvs the "hang after /proc/ide read" problem, which
was in fact a memory corruption problem.
