The ipmi_devintf module contains the userspace interface for IPMI devices,
yet will not be loaded automatically with a system interface handler
driver.
Add a MODULE_ALIAS for the "platform:ipmi_si" MODALIAS exported by the
ipmi_si driver, so that userspace knows of the recommendation.

For the time being build for ia64-sn2 alone when CONFIG_IA64_GENERIC is
specified.
This eliminates a dependency of the XP/XPC drivers on having the GRU
driver insmod'd in order to insmod them, when running on an ia64-sn2
system.
On such a system the GRU driver serves no useful purpose.

This patch (as1153) fixes a potential problem in hub initialization.
Starting in 2.6.28, initialization was split into several tasks to
help speed up booting. This opens the possibility that the hub may be
autosuspended before all the initialization tasks can complete.
Normally that wouldn't matter, but with incomplete initialization
there is a risk that the hub would never autoresume -- especially if
devices were plugged into the hub beforehand. The solution is a
simple one-line change to suppress autosuspend until the
initialization is finished.

This patch (as1151) protects usbcore against drivers that try to
unlink an URB after the URB's device or bus have been removed. The
core does not currently check for this, and certain drivers can cause
a crash if they are running while an HCD is unloaded.
Certainly it would be best to fix the guilty drivers. But a little
defensive programming doesn't hurt, especially since it appears that
quite a few drivers need to be fixed.
The patch prevents the problem by grabbing a reference to the device
while an unlink is in progress and using a new spinlock to synchronize
unlinks with device removal. (There's no need to acquire a reference
to the bus as well, since the device structure itself keeps a
reference to the bus.) In addition, the kerneldoc is updated to
indicate that URBs should not be unlinked after the disconnect method
returns.

Add an appropriate entry for the Promise PDC42819 controller. It has an
AHCI mode and so far works correctly with board_ahci.
This chip is found on Promise's FastTrak TX2650 (2 port) and TX4650 (4 port)
software-based RAID cards (for which there is a binary driver, t3sas) and
can be found on some motherboards, for example the MSI K9A2 Platinum,
which calls the chip a Promise T3 controller.
Although this controller also supports SAS devices, its default bootup mode
is AHCI and the binary driver has to do some magic to get the chip into the
appropriate mode to drive SAS disks.
Seeing as no documentation is provided by Promise, adding this entry to the
ahci driver allows the controller to be useful to people as a SATA
controller (with no ill effects on the system if a SAS disk is connected -
probing of the port just times out with "link online but device
misclassified"), without having to resort to using the binary driver. Users
who require SAS or the proprietary software raid can get this functionality
using the binary driver.

Note the unresolved format string.
dev->name is unavailable before register_netdev, so use
dev_driver_string(&pdev->dev), which is also consistent with other
drivers.
"char *devname" parameters had to be converted to "const char *devname" to
be consistent with dev_driver_string return value.
