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.

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

interface.)

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.

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.
