* blk_end_request: changing ide-cd (take 4)Kiyoshi Ueda2008-01-281-14/+35
| | | | | | | | | | | | | | | | | | | | This patch converts ide-cd (cdrom_newpc_intr()) to use blk_end_request interfaces. Related 'uptodate' arguments are converted to 'error'. In PIO mode, ide-cd (cdrom_newpc_intr()) needs to defer end_that_request_last() until the device clears DRQ_STAT and raises an interrupt after end_that_request_first(). So blk_end_request() has to return without completing request even if no leftover in the request. ide-cd uses blk_end_request_callback() and a dummy callback function, which just returns value '1', to tell blk_end_request_callback() about that.

* blk_end_request: changing ide normal caller (take 4)Kiyoshi Ueda2008-01-282-16/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts "normal" parts of ide to use blk_end_request interfaces. Related 'uptodate' arguments are converted to 'error'. The conversion of 'uptodate' to 'error' is done only for the internal function, __ide_end_request(). ide_end_request() was not changed since it's exported and used by many ide drivers. With this patch, blkdev_dequeue_request() in __ide_end_request() is moved to blk_end_request, since blk_end_request takes care of dequeueing request like below: if (!list_empty(&rq->queuelist)) blkdev_dequeue_request(rq); In the case of ide, o 'dequeue' variable of __ide_end_request() is 1 only when the request is still linked to the queue (i.e. rq->queuelist is not empty) o 'dequeue' variable of __ide_end_request() is 0 only when the request has already been removed from the queue (i.e. rq->queuelist is empty) So blk_end_request can handle it correctly although ide always run thought the code above.

| | | | | | | | | | | | | | | | | | | In ide_taskfile_ioctl(), there was a race condition involving drive->io_32bit. It was cleared and restored during ioctl requests but there was no synchronization with other requests. So, other requests could execute with the altered ->io_32bit setting or updated drive->io_32bit could be overwritten by ide_taskfile_ioctl().

* ide: don't try to unregister interfaces if 'initializing' in ide_register_hw()Bartlomiej Zolnierkiewicz2008-01-261-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Host drivers using ide_register_hw() and 'initializing == 1': * ide-pnp - depends on ISA * ide_arm - ARM arch specific - initialized before all other host drivers * ide-cris - CRIS arch specific => IDE_ARCH_OBSOLETE_INIT is not defined - broken * ide-h8300 - H8300 arch specific => IDE_ARCH_OBSOLETE_INIT is not defined, no PCI * buddha/q40/gayle/macide/falconide - M68K arch specific => IDE_ARCH_OBSOLETE_INIT is not defined, no PCI Since the only host drivers which probe interfaces before the above ones are: * ali14xx/dtc2278/ht6560b/qd65xx/umc8672 - depend on ISA - require IDE_ARCH_OBSOLETE_INIT=y to work * PCI ones - depend on PCI don't try to unregister interfaces if 'initializing == 1' in ide_register_hw() (it is possible that built-in host drivers will claim all IDE interfaces but later ide-pnp host driver will try to unregister them - this change fixes it). Also skip hwif->hold check if 'initializing == 1' since it is set only by: * pmac - PPC && PMAC specific => no ISA * au1xxx-ide - MIPS && SOC_AU1200 specific => no ISA and use ide_find_port() helper to find free ide_hwifs[] slot.

* ide: merge ->fixup and ->quirkproc methodsBartlomiej Zolnierkiewicz2008-01-268-62/+53
| | | | | | | | | | | | | | | | | | | | | | | | | * Assign drive->quirk_list in ->quirkproc implementations: - hpt366.c::hpt3xx_quirkproc() - pdc202xx_new.c::pdcnew_quirkproc() - pdc202xx_old.c::pdc202xx_quirkproc() * Make ->quirkproc void. * Move calling ->quirkproc from do_identify() to probe_hwif(). * Convert it821x_fixups() to it821x_quirkproc() in it821x.c. * Convert siimage_fixup() to sil_quirkproc() in siimage.c, also remove no longer needed drive->present check from is_dev_seagate_sata(). * Convert ide_undecoded_slave() to accept 'drive' instead of 'hwif' as an argument. Then convert ide_register_hw() to accept 'quirkproc' argument instead of 'fixup' one. * Remove no longer needed ->fixup method.
