These days ioctl32.h is only used for communication of fs/compat.c and
fs/compat_ioctl.c and doesn't contain anything of interest to drivers.Remove inclusion in various drivers.

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.Signed-Off-By: Andrew Chew

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.Signed-off-by: Christoph Hellwig

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.Signed-off-by: Benjamin Herrenschmidt

Manual fixup for merge with Jens' "Suspend support for libata", commit

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.Signed-off-by: Jens Axboe

add @uptodate argument to end_that_request_last() and @error
to rq_end_io_fn(). there's no generic way to pass error code
to request completion function, making generic error handling
of non-fs request difficult (rq->errors is driver-specific and
each driver uses it differently). this patch adds @uptodate
to end_that_request_last() and @error to rq_end_io_fn().for fs requests, this doesn't really matter, so just using the
same uptodate argument used in the last call to
end_that_request_first() should suffice. imho, this can also
help the generic command-carrying request jens is working on.Signed-off-by: tejun heo

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

Move the suspend and resume methods out of the event handler, and into

almost all drivers already do, and the remaining ones can easily be

Leave the overloaded "hotplug" word to susbsystems which are handling
real devices. The driver core does not "plug" anything, it just exports
the state to userspace and generates events.Signed-off-by: Kay Sievers

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

The oops is characteristic of the underlying device being removed from
visibility before the class device, and sure enough we do device_del()
before transport_unregister() in the scsi_target_reap() routines. I've
no idea why this is suddenly showing up, since the code has been in
there since that function was first invented. However, I've confirmed
this fixes Andrew Vasquez's boot oops.Signed-off-by: James Bottomley

Miquel van Smoorenburg forwarded me this fix to
resolve a deadlock condition that occurs due to the API change in
2.6.13+ kernels dropping the host locking when entering the error
handling. They all end up calling adpt_i2o_post_wait(), which if you
call it unlocked, might return with host_lock locked anyway and that
causes a deadlock.Signed-off-by: Mark Salyzyn
