2008-07-23ide: pass hw_regs_t-s to ide_device_add[_all]() (take 3)Bartlomiej Zolnierkiewicz
* Add 'hw_regs_t **hws' argument to ide_device_add[_all]() and convert host drivers + ide_legacy_init_one() + ide_setup_pci_device[s]() to use it instead of calling ide_init_port_hw() directly. [ However if host has > 1 port we must still set hwif->chipset to hint consecutive ide_find_port() call that the previous slot is occupied. ] * Unexport ide_init_port_hw(). v2: * Use defines instead of hard-coded values in buddha.c, gayle.c and q40ide.c. (Suggested by Geert Uytterhoeven) * Better patch description. v3: * Fix build problem in ide-cs.c. (Noticed by Stephen Rothwell) There should be no functional changes caused by this patch.

While at it: - fix return value (s/-ENODEV/-ENOENT/) - add DRV_NAME define and use it to set name field of pmac_port_info - use ide_find_port_slot() instead of ide_find_port() - remove superfluous error message (ide_find_port_slot() takes care of it) - drop IDE interface number from driver banner message (but include bus type) v2: * Build fix (thanks to Stephen Rothwell for noticing the issue).

2008-07-16IDE: Report errors during drive reset back to user spaceElias Oltmanns
Make sure that each error condition during the execution of an HDIO_DRIVE_RESET ioctl is actually reported to the calling process. Also, unify the exit path of reset_pollfunc() when returning ide_stopped since the need of ->port_ops->reset_poll() to be treated specially has vanished (way back, it seems).

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-cd: fold cdrom_start_seek into ide_cd_do_requestBorislav Petkov
