2008-07-16Update documentation of HDIO_DRIVE_RESET ioctlElias Oltmanns
Alter the entry for HDIO_DRIVE_RESET in Documentation/ioctl/hdio.txt to reflect a functional change in the driver. Besides, the entry has been inaccurate before.

2008-07-16IDE: Remove unused codeElias Oltmanns
Remove some code which has been made obsolete and hasn't worked properly before anyway. Part of the infrastructure may be reintroduced in a follow up patch to implement a working command aborting facility.

2008-07-16IDE: Fix HDIO_DRIVE_RESET handlingElias Oltmanns
Currently, the code path executing an HDIO_DRIVE_RESET ioctl is broken in various ways. Most importantly, it is treated as an out of band request in an illegal way which may very likely lead to system lock ups. Use the drive's request queue to avoid this problem (and fix a locking issue for free along the way).

2008-07-16ide-floppy: zero out the whole struct ide_atapi_pc on initBorislav Petkov

2008-07-16ide-cd: fold cdrom_start_seek into ide_cd_do_requestBorislav Petkov
Do what the compiler does anyway: inline a function that is used only once. This saves us the overhead of a function call and the function is small enough to be embedded in the callsite anyways.
