| * [PATCH] powerpc: Remove device_node addrs/n_addrBenjamin Herrenschmidt2006-01-08
| | | | | | | | | | | | | | | | | | | | | | | | The pre-parsed addrs/n_addrs fields in struct device_node are finally gone. Remove the dodgy heuristics that did that parsing at boot and remove the fields themselves since we now have a good replacement with the new OF parsing code. This patch also fixes a bunch of drivers to use the new code instead, so that at least pmac32, pseries, iseries and g5 defconfigs build.

| * | [PATCH] sata_nv, spurious interrupts at system startup with MAXTOR 6H500F0 driveAndrew Chew2006-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch works around a problem with spurious interrupts seen at boot time when a MAXTOR 6H500F0 drive is present. An ATA interrupt condition is mysteriously present at start of day. If we took too long in issuing the first command, the kernel would basically get tired of the spurious interrupts and turn the interrupt off. Issuing the first command essentially causes the interrupt condition to get acknowledged. I haven't seen this happen with any other drives. What I basically do is ack ATA status by reading it regardless of whether we're expecting to have to handle an interrupt. This clears the start-of-day anomalous interrupt condition, and keeps the kernel from disabling that interrupt due to too many spurious interrupts. Also, I fixed a bug where hotplug interrupts weren't getting acknowledged as handled in the ISR. This was not the cause of the spurious interrupts, but it's the right thing to do anyway.

* / [PATCH] Add block_device_operations.getgeo block device methodChristoph Hellwig2006-01-08
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | HDIO_GETGEO is implemented in most block drivers, and all of them have to duplicate the code to copy the structure to userspace, as well as getting the start sector. This patch moves that to common code [1] and adds a ->getgeo method to fill out the raw kernel hd_geometry structure. For many drivers this means ->ioctl can go away now. [1] the s390 block drivers are odd in this respect. xpram sets ->start to 4 always which seems more than odd, and the dasd driver shifts the start offset around, probably because of it's non-standard sector size.

* | [PATCH] Suspend support for libataJens Axboe2006-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds suspend patch to libata, and ata_piix in particular. For most low level drivers, they should just need to add the 4 hooks to work. As I can only test ata_piix, I didn't enable it for more though. Suspend support is the single most important feature on a notebook, and most new notebooks have sata drives. It's quite embarrassing that we _still_ do not support this. Right now, it's perfectly possible to suspend the drive in mid-transfer.

* [PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe ↵Dominik Brodowski2006-01-05
| | | | | | | | | | | | | | | | | | | | | | callback Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified probe() callback. As all in-kernel drivers are changed to this new callback, there will be no temporary backwards-compatibility. Inside a probe() function, each driver _must_ set struct pcmcia_device *p_dev->instance and instance->handle correctly. With these patches, the basic driver interface for 16-bit PCMCIA drivers now has the classic four callbacks known also from other buses: int (*probe) (struct pcmcia_device *dev); void (*remove) (struct pcmcia_device *dev); int (*suspend) (struct pcmcia_device *dev); int (*resume) (struct pcmcia_device *dev); Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The distinction between hotplug and uevent does not make sense these days, netlink events are the default. udev depends entirely on netlink uevents. Only during early boot and in initramfs, /sbin/hotplug is needed. So merge the two functions and provide only one interface without all the options. The netlink layer got a nice generic interface with named slots recently, which is probably a better facility to plug events for subsystem specific events. Also the new poll() interface to /proc/mounts is a nicer way to notify about changes than sending events through the core. The uevents should only be used for driver core related requests to userspace now. Signed-off-by: Kay Sievers <kay.sievers@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Previously, this was done by each user by manually initializing a qc, issueing it, waiting for its completion and handling errors. In addition to obvious code factoring, using ata_exec_internal() fixes the following bugs. * qc not freed on issue failure * ap->qactive clearing could race with the next internal command * race between timeout handling and irq * ignoring error condition not represented in tf->status Also, qc & hardware are not accessed anymore once it's completed, making internal commands more conformant with general semantics. ata_exec_internal() also makes it easy to issue internal commands from multiple threads if that becomes necessary. This patch only implements ata_exec_internal(). A following patch will convert all users. Signed-off-by: Tejun Heo <htejun@gmail.com> -- Jeff, all patches have been regenerated against upstream branch as of today. (575ab52a218e4ff0667a6cbd972c3af443ee8713) Also, I took out a debug printk from ata_exec_internal (don't know how that one got left there). Other than that, all patches are identical to the previous posting. Thanks. :-) Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
