IB/ehca: SRQ fixes to enable IPoIB CM
IB/ehca: Fix Small QP regressions
The HPET clocksource in drivers/char/hpet.c was written as generic code
for ia64, but it is not yet ready to replace the native HPET clocksource
implementations that the i386/x86-64 architectures use.
On x86[-64], trying to register this clocksource results in potentially
multiple hpet-based clocksources being registered, and if the ia64 one
is chosen on x86_64 some users have experienced hangs.
Eventually all three architectures may end up using the same code, but
that is not the case right now.

cxgb3 - Fix dev->priv usage
qeth: Drop ARP packages on HiperSockets interface with NOARP attribute.
qeth: provide specific message for OSA-adapters exclusively used
qeth: crash during reboot after failing online setting
qeth: Announce tx checksumming for qeth devices in TSO/EDDP mode
qeth: dont return the return values of void functions.
qeth: enforce a rate limit for inbound scatter gather messages
qeth: ungrouping a device must not be interruptible
netxen: fix crashes during module unload
netxen: Avoid firmware load in PCI probe
PS3: fix the bug that 'ifconfig down' would hang
IOC3: Program UART predividers.
Fix ehca SRQ support so that IPoIB connected mode works:
- Report max_srq > 0 if SRQ is supported
- Report "last wqe reached" asynchronous event when base QP dies;
this is required by the IB spec and IPoIB CM relies on receiving it
when cleaning up.

A network interface can get ARP packets even when the interface has
NOARP specified. In a HiperSockets environment this disturbs receiving
systems when packets are sent on the multicast queue. (E.g. TCP/IP on
z/VM issues messages reporting invalid data on the HiperSockets
interface.)
Qeth will no longer send ARP packets on HiperSockets interface when
interface has the NOARP attribute.

Online setting of a qeth device may fail for instance because of:
- out-of-memory condition when allocating qdio queues
- IDX ACTIVATE problem
- ...
Such a device is still returned in a driver_for_each_device loop
processed in qeth_reboot_event(), which calls
qeth_clear_qdio_buffers(). Make sure qeth_clear_output_buffer() is
called only, if the qdio queues have been successfully allocated
during initialization of a qeth device.

Problem:
A recovery thread must not be active when device is removed.
In qeth_remove_device() an interruptible wait operation is used
to wait until a qeth recovery thread is finished. If a user really
interrupts the ungroup operation of a qeth device while a recovery
is running, cio and qeth are out of sync (device already removed
from cio, but kept in qeth). A following module unload of qeth
results in a kernel OOPS here.
Solution:
Do not allow interruption of ungroup operation to guarantee
finishing of a potentially running qeth recovery thread.

The IOC3 driver's UART detection bits used to rely on the the firmware
setting the UART pre-divider in a way that's apropriate for the 8250
driver which doesn't currently program this register. This happens
to work for the console but not rarely for additional ports.
While at it, also program the UART to RS-232 PIO mode; it the UART might

0x4385, instead of the already submitted 0x4395.
Besides removing the wrong SB700 device ID, add SB800 support to kernel, by

Update various SPI drivers so they properly support
- coldplug through "modprobe $(cat /sys/devices/.../modalias)"
- hotplug through "modprobe $(MODALIAS)"
The basic rule for platform, SPI, and (new style) I2C drivers is just
to make sure that modprobing the driver name works. In this case, all
the relevant drivers are platform drivers, and this patch either
(a) Changes the driver name, if no in-tree code would break;
this is simpler and thus preferable in the long term.
(b) Adds MODULE_ALIAS directives, when in-tree platforms declare
devices using the current driver name; less desirable.
Most systems will link SPI controller drivers statically, but
there's no point in being needlessly broken.

This patch corrects sata_promise to classify FastTrack TX4200
(DID 3515/3519) as a second-generation chip. Promise's partial-
source FT TX4200 driver confirms this classification.
Treating it as a first-generation chip causes several problems:
1. Detection failures. This is a recent regression triggered by
the hotplug-enabling changes in 2.6.23-rc1.
2. Various "failed to resume link for reset" warnings.
This patch fixes <http://bugzilla.kernel.org/show_bug.cgi?id=8936>.
