Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

amd74xx: workaround unreliable AltStatus register for nVidia controllers It seems that on some nVidia controllers using AltStatus register can be unreliable so default to Status register if the PCI device is in Compatibility Mode. In order to achieve this: * Add ide_pci_is_in_compatibility_mode() inline helper to <linux/ide.h>. * Add IDE_HFLAG_BROKEN_ALTSTATUS host flag and set it in amd74xx host driver for nVidia controllers in Compatibility Mode. * Teach actual_try_to_identify() and drive_is_ready() about the new flag. This fixes the regression caused by removal of CONFIG_IDEPCI_SHARE_IRQ config option in 2.6.25 and using AltStatus register unconditionally when available (kernel.org bugs #11659 and #10216). [ Moreover for CONFIG_IDEPCI_SHARE_IRQ=y (which is what most people and distributions use) it never worked correctly. ] Thanks to Remy LABENE and Lars Winterfeld for help with debugging the problem.

ide: allow ide_dev_read_id() to be called from the IRQ context * Un-static __ide_wait_stat(). * Allow ide_dev_read_id() helper to be called from the IRQ context by adding irq_ctx flag and using mdelay()/__ide_wait_stat() when needed. * Switch ide_driveid_update() to set irq_ctx flag. This change is needed for the consecutive patch which fixes races in handling of user-space SET XFER commands but for improved bisectability and clarity it is better to do it in a separate patch.

ide: fix PowerMac bootup oops PowerMac bootup with CONFIG_IDE=y oopses in ide_pio_cycle_time(): because "ide: try to use PIO Mode 0 during probe if possible" causes pmac_ide_set_pio_mode() to be called before drive->id has been set. Bart points out other places which now need drive->id set earlier, so follow his advice to allocate it in ide_port_alloc_devices() (using kzalloc_node, without error message, as when allocating drive) and memset it for reuse in ide_port_init_devices_data(). Fixed in passing: ide_host_alloc() was missing ide_port_free_devices() from an error path.

Even if there would be a drive there and it is still busy afterwards it should not matter since it isn't probed for later. The code also honors the MAX_DRIVES variable instead of assuming that there will be two harddrives on the bus.

[ conflict in drivers/ide/ide-probe.c fixed manually ] It turned out that probing order change causes problems for some drives: http://bugzilla.kernel.org/show_bug.cgi?id=10239 Since root causes are still being investigated and are unlikely to be fixed before 2.6.25 lets revert this change for now. As a result cable detection becomes less reliable when compared with 2.6.24 but the affected drives are useable again.

it821x: RAID mode fixes The DMA support for RAID mode broke after: commit 71ef51cc1756d1c56b57c70e7cc27a3559c81ee6 Author: Jens Axboe <axboe@suse.de> Date:   Fri Jul 28 09:02:17 2006 +0200     [PATCH] it821x: fix ide dma setup bug     Only enable dma for a valid speed setting.     Signed-off-by: Jens Axboe <axboe@suse.de> commit 0a8348d08677ad77ee353f96eb8745c693a05a13 Author: Jens Axboe <axboe@suse.de> Date:   Fri Jul 28 08:58:26 2006 +0200     [PATCH] ide: if the id fields looks screwy, disable DMA     It's the safer choice. Originally due to a bug in itx821x, but a     generally sound thing to do.     Signed-off-by: Jens Axboe <axboe@suse.de> However it worked by pure luck before Jens' fixes: bogus ide_dma_enable() usage in it821x driver combined with loosy check in ide_dma_verbose() allowed the hardware to operate in DMA mode. When these problems were fixed the DMA support broke... The source root for the regression turned out to be that the it821x.c code was clearing too much of id->field_valid. The IDE core code was using the original value of id->field_valid to do the tuning but later DMA got disabled in ide_dma_verbose() because of the incorrect id->field_valid fixup. Fix it. While at it: * Do fixup() after probing the drives but before tuning them (which is also OK w.r.t. ide_undecoded_slave() fixup). This change fixes device IDENTIFY data to be consistent before/after the tuning and allows us to remove extra re-tuning of drives from it821x_fixups(). * Fake MWDMA0 enabled/supported bits in IDENTIFY data if the device has DMA capable bit set (this is just to tell the IDE core that DMA is supported since it821x firmware takes care of DMA mode programming). * Don't touch timing registers and don't program transfer modes on devices et all when in RAID mode - depend solely on firmware to do the tuning (as suggested by Alan Cox and done in libata pata_it821x driver).

m68k/atari - ide: do not register interrupt if host->get_lock is set On m68k, host->get_lock is used to both lock and register the interrupt that the IDE host shares with other device drivers. Registering the IDE interrupt handler in ide-probe.c results in duplicating the interrupt registered (once via host->get lock, and also via init_irq()), and may result in IDE accepting interrupts even when another driver has locked the interrupt hardware. This opens the whole locking scheme up to races. host->get_lock is set on m68k only, so other drivers' behaviour is not changed.

This patch should fix the incorrect grouping of port(s) from host(s) that need serialization with port(s) that happen to use the same IRQ(s) but are from the host(s) that don't need it.

Bart points out other places which now need drive->id set earlier, so follow his advice to allocate it in ide_port_alloc_devices() (using kzalloc_node, without error message, as when allocating drive) and memset it for reuse in ide_port_init_devices_data().

ide: Fix host drivers that need IRQF_SHARED commit 255115fb35f80735c21a1cbe9809e9795a3af26e ("ide: allow host drivers to specify IRQ flags") added irq_flags fields to struct ide_port_info and struct ide_host. Drivers can now set ide_port_info.irq_flags = IRQF_SHARED, while init_irq() passes ide_host.irq_flags to request_irq(). Unfortunately ide_host.irq_flags is never set, causing (on ARAnyM): | Uniform Multi-Platform E-IDE driver | ide: Falcon IDE controller | Probing IDE interface ide0... | hda: Sarge m68k, ATA DISK drive | init_irq: sa = 0 | ide0: disabled, unable to get IRQ 15 | ide0: failed to initialize IDE interface | ide0: disabling port Solve this by copying ide_port_info.irq_flags to ide_host.irq_flags in ide_host_alloc().

m68k/atari - ide: do not register interrupt if host->get_lock is set On m68k, host->get_lock is used to both lock and register the interrupt that the IDE host shares with other device drivers. Registering the IDE interrupt handler in ide-probe.c results in duplicating the interrupt registered (once via host->get lock, and also via init_irq()), and may result in IDE accepting interrupts even when another driver has locked the interrupt hardware. This opens the whole locking scheme up to races. host->get_lock is set on m68k only, so other drivers' behaviour is not changed.

ide: rework PowerMac media-bay support (take 2) Rework PowerMac media-bay support in such way that instead of un/registering the IDE interface we un/register IDE devices: * Add ide_port_scan() helper for probing+registerering devices on a port. * Rename ide_port_unregister_devices() to __ide_port_unregister_devices(). * Add ide_port_unregister_devices() helper for unregistering devices on a port. * Add 'ide_hwif_t *cd_port' to 'struct media_bay_info', pass 'hwif' instead of hwif->index to media_bay_set_ide_infos() and use it to setup 'cd_port'. * Use ide_port_unregister_devices() instead of ide_unregister() and ide_port_scan() instead of ide_register_hw() in media_bay_step(). * Unexport ide_register_hw() and make it static. v2: * Fix build by adding <linux/ide.h> include to <asm-powerpc/mediabay.h>.

ide: fix ide_port_scan() to do ACPI setup after initializing request queues This makes ide_port_scan()'s behavior match ide_host_register()'s one and fixes OOPS in elv_may_queue() during port re-scan.
