IPR scsi adapter have an exposure today in that they issue BIST to the adapter
to reset the card. If, during the time it takes to complete BIST, userspace
attempts to access PCI config space, the host bus bridge will master abort the
access since the ipr adapter does not respond on the PCI bus for a brief
period of time when running BIST. On PPC64 hardware, this master abort
results in the host PCI bridge isolating that PCI device from the rest of the
system, making the device unusable until Linux is rebooted. This patch makes
use of some newly added PCI layer APIs that allow for protection from
userspace accessing config space of a device in scenarios such as this.

The previous patch adding the ability to nest struct class_device
changed the paramaters to the call class_device_create(). This patch
fixes up all in-kernel users of the function.

Driver core: pass interface to class intreface methods
Pass interface as argument to add() and remove() class interface
methods. This way a subsystem can implement generic add/remove
handlers and then call interface-specific ones.

If qla2x00_probe_one()'s call to qla2x00_iospace_config() fails, we call
qla2x00_free_device() to clean up. But because ha->dpc_pid hasn't been set
yet, qla2x00_free_device() tries to stop a kernel thread which hasn't started
yet. It does wait_for_completion() against an uninitialised completion struct
and the kernel hangs up.
Fix it by initialising ha->dpc_pid a bit earlier.

sata_qstor strays into a nasty area - gcc handling of wide enums is
full of bugs that got fixed between gcc versions creating portability
nightmare. Single-member enums are safe, so are ones that stay within
the range of int or unsigned int. Anything beyond that is asking for
trouble.
Declaration of constants split in two enums, taking the ~0UL one into
a separate enum.

This change makes quirk_intel_ide_combined() dependent on the precise
conditions under which it is needed:
* IDE is built in
* IDE SATA option is not set
* ata_piix or ahci drivers are enabled
This fixes an issue where some modular configurations would not cause
the quirk to be enabled.

When a request is deferred in scsi_init_io because the sg table could not
be allocated, the associated scsi_cmnd is not released and the request is
not marked with REQ_DONTPREP. When the command is retried, if
scsi_prep_fn decides to kill it then the scsi_cmnd will never be released.
This patch (as573) changes scsi_init_io so that it calls scsi_put_command
before deferring a request.

Juan was kind enough to linger on site, and work on a production
machine, to try the parameter to make the system stable. He discovered
that reducing the maximum transfer size issued to the adapter to 128KB
stabilized his system. This is related to an earlier change for the
2.6.13 tree resulting from Martin Drab's testing where the transfer size
was reduced from 4G to 256KB; we needed to go still further in scaling
back the request size.
Here is the patch that tames this regression.
