2008-04-21cdrom: make unregister_cdrom() return voidAkinobu Mita1-3/+2
Now unregister_cdrom() always returns 0. Make it return void and update all callers that check the return value.

2008-04-18ide: remove ide_init_default_irq() macroBartlomiej Zolnierkiewicz1-1/+1
* Use ide_default_irq() instead of ide_init_default_irq() in ide_generic host driver (so the correct IRQ is always set regardless of CONFIG_PCI / CONFIG_BLK_DEV_IDEPCI). * Remove no longer needed ide_init_default_irq() macro. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-18ide: move default IDE ports setup to ide_generic host driverBartlomiej Zolnierkiewicz3-23/+10

* Remove obsoleted "idex=noprobe" kernel parameter. * Remove no longer needed hwif->noprobe quirk from ide_hwif_configure() and hwif->noprobe checking from cmd640.c. v2: * "ide?=noprobe" -> "ide?=ata66" in Documentation/kernel-parameters.txt.

2008-04-18ide: remove needless hwif->irq check from ide_hwif_configure()Bartlomiej Zolnierkiewicz1-1/+1

2008-04-18ide: init hwif->{io_ports,irq} explicitly in legacy VLB host driversBartlomiej Zolnierkiewicz6-5/+72
Do explicit port setup in legacy VLB host drivers instead of depending on init_ide_data(). This way hwif->io_ports[] and hwif->irq are always correctly set regardless of CONFIG_PCI / CONFIG_BLK_DEV_IDEPCI. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-18ide: limit legacy VLB host drivers to alpha, x86 and mipsBartlomiej Zolnierkiewicz1-1/+1
These host drivers indirectly depend on CONFIG_IDE_ARCH_OBSOLETE_DEFAULTS=y which is defined only on alpha, x86, ia64, m32r, mips and ppc32. Moreover: - on ia64 there is no ISA - m32r is too new for VLB - on ppc32 ISA is available only on PPC_CHRP (no default IDE ports) and PPC_PREP (marked as BROKEN) [ the common sense tells me that VLB was only used on x86 but there are urban legends that one of these host drivers was needed on some other arch - thus the extra care ] Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-04-18ide: remove broken/dangerous HDIO_[UNREGISTER,SCAN]_HWIF ioctls (take 3)Bartlomiej Zolnierkiewicz10-206/+15
hdparm explicitely marks HDIO_[UNREGISTER,SCAN]_HWIF ioctls as DANGEROUS and given the number of bugs we can assume that there are no real users: * DMA has no chance of working because DMA resources are released by ide_unregister() and they are never allocated again. * Since ide_init_hwif_ports() is used for ->io_ports[] setup the ioctls don't work for almost all hosts with "non-standard" (== non ISA-like) layout of IDE taskfile registers (there is a lot of such host drivers). * ide_port_init_devices() is not called when probing IDE devices so: - drive->autotune is never set and IDE host/devices are not programmed for the correct PIO/DMA transfer modes (=> possible data corruption) - host specific I/O 32-bit and IRQ unmasking settings are not applied (=> possible data corruption) - host specific ->port_init_devs method is not called (=> no luck with ht6560b, qd65xx and opti621 host drivers) * ->rw_disk method is not preserved (=> no HPT3xxN chipsets support). * ->serialized flag is not preserved (=> possible data corruption when using icside, aec62xx (ATP850UF chipset), cmd640, cs5530, hpt366 (HPT3xxN chipsets), rz1000, sc1200, dtc2278 and ht6560b host drivers). * ->ack_intr method is not preserved (=> needed by ide-cris, buddha, gayle and macide host drivers). * ->sata_scr[] and sata_misc[] is cleared by ide_unregister() and it isn't initialized again (SiI3112 support needs them). * To issue an ioctl() there need to be at least one IDE device present in the system. * ->cable_detect method is not preserved + it is not called when probing IDE devices so cable detection is broken (however since DMA support is also broken it doesn't really matter ;-). * Some objects which may have already been freed in ide_unregister() are restored by ide_hwif_restore() (i.e. ->hwgroup). * ide_register_hw() may unregister unrelated IDE ports if free ide_hwifs[] slot cannot be found. * When IDE host drivers are modular unregistered port may be re-used by different host driver that owned it first causing subtle bugs. Since we now have a proper warm-plug support remove these ioctls, then remove no longer needed: - ide_register_hw() and ide_hwif_restore() functions - 'init_default' and 'restore' arguments of ide_unregister() - zeroeing of hwif->{dma,extra}_* fields in ide_unregister() As an added bonus IDE core code size shrinks by ~3kB (x86-32). v2: * fix ide_unregister() arguments in cleanup_module() (Andrew Morton). v3: * fix ide_unregister() arguments in palm_bk3710.c.

* Use ide_find_port() instead of ide_deprecated_find_port() in bast-ide/ palm_bk3710/ide-cs/delkin_cb host drivers and in ide_register_hw(). * Remove no longer needed ide_deprecated_find_port(). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-18ide: fix ide_find_port()Bartlomiej Zolnierkiewicz2-2/+2
* Instead of checking for '->io_ports[IDE_DATA_OFFSET] == 0' check for '->chipset == ide_unknown' when looking for an empty ide_hwifs[] slot. * Do ide-pnp initialization after ide-generic when IDE is built-in (ide-pnp is the only user of ide_find_port() which needs such fixup).
