dasd driver changes:
- The feature check in dasd_generic_online returns an error if
the devmap entry for the device is not yet available. Check
for the feature after the device has been created.
- Do symmetric registration/deregistration of cdev->handler.

Updates to the usbnet driver:
- Remove a warning when built with Zaurus support but not CDC Ethernet;
just moves an #ifdef to cover more code
- Two tweaks to the pseudo-MDLM support:
* correctly handle _either_ of the two GUIDs
* ignore a padding bit that doesn't seem necessary
- Remove ID for one Motorola phone that uses the MDLM stuff.
It also updates the Kconfig helptext to make it clearer that the "Zaurus"
configuration option supports an increasing (sigh) family of nonstandard
peripheral protocols.

ioctl_by_bdev may only be used INSIDE the kernel. If the "arg" argument
refers to memory that is accessed by put_user/get_user in the ioctl
function, the memory needs to be in the kernel address space (that's the
set_fs(KERNEL_DS) doing in the ioctl_by_bdev). This works on i386 because
even with set_fs(KERNEL_DS) the user space memory is still accessible with
put_user/get_user. That is not true for s390. In short the ioctl
implementation of the pktcdvd device driver is horribly broken.

[Patch] Fix raw device ioctl pass-through
Raw character devices are supposed to pass ioctls through to the block
devices they are bound to. Unfortunately, they are using the wrong
function for this: ioctl_by_bdev(), instead of blkdev_ioctl().
ioctl_by_bdev() performs a set_fs(KERNEL_DS) before calling the ioctl,
redirecting the user-space buffer access to the kernel address space.
This is, needless to say, a bad thing.
This was noticed first on s390, where raw IO was non-functioning. The
s390 driver config does not actually allow raw IO to be enabled, which
was the first part of the problem. Secondly, the s390 kernel address
space is distinct from user, causing legal raw ioctls to fail. I've
reproduced this on a kernel built with 4G:4G split on x86, which fails
in the same way (-EFAULT if the address does not exist kernel-side;
returns success without actually populating the user buffer if it does.)
The patch below fixes both the config and address-space problems. It's
based closely on a patch by Jan Glauber <jang@de.ibm.com>, which has
been tested on s390 at IBM. I've tested it on x86 4G:4G (split address
space) and x86_64 (common address space).
Kernel-address-space access has been assigned CAN-2005-1264.

===================================================================
Problem:
During the libata CD-ROM stress test, sometimes the "BUG: timeout
without command" error is seen.
Root cause:
Unexpected interrupt occurs after the ata_qc_complete() is called,
but before the SCSI error handler. The interrupt handler is invoked
before the SCSI error handler, and it clears the command by calling
ata_qc_complete() again. Later when the SCSI error handler is run,
the ata_queued_cmd is already gone, causing the "BUG: timeout without
command" error.
Changes:
- Use the ATA_QCFLAG_ACTIVE flag to prevent the interrupt handler
from completing the command twice, before the scsi_error_handler.
