7097228c54 IB/mad: Don't discard BMA responses in kernel
This fixes the problem of incoming BMA responses being dropped due to
a bad "is response" check.  Fix the test to use the ib_response_mad()
predicate, which correctly handles BMA MADs.

b9012e0a42 IB/ehca: Generate flush status CQ entries
When a QP goes into error state, it is required that CQ entries with a
flush error status are delivered to the application for any
outstanding work requests.  eHCA does not do this in hardware, so this
patch adds software flush CQE generation to the ehca driver.

Whenever a QP gets into error state, it is added to the QP error list
of its respective CQ.  If the error QP list of a CQ is not empty,
poll_cq() generates flush CQEs before polling the actual CQ.

a650031a6b mmc_test: initialize mmc_test_lock statically
The mutex mmc_test_lock is initialized at every time mmc_test device
is probed. Probing another mmc_test device may break the mutex, if
the probe function is called while the mutex is locked.

This patch fixes it by statically initializing mmc_test_lock.

170e7108a3 mv643xx_eth: fix receive checksumming
We have to explicitly tell the hardware to include the pseudo-header
when doing receive checksumming, otherwise hardware checksumming will
fail for every received packet and we'll end up setting CHECKSUM_NONE
on every received packet.

While we're at it, when skb->ip_summed is set to CHECKSUM_UNNECESSARY
on received packets, skb->csum is supposed to be undefined, and thus
there is no need to set it.

9744197c3d md: Don't wait UNINTERRUPTIBLE for other resync to finish
When two md arrays share some block device (e.g each uses different
partitions on the one device), a resync of one array will wait for
the resync on the other to finish.

This can be a long time and as it currently waits TASK_UNINTERRUPTIBLE,
the softlockup code notices and complains.

So use TASK_INTERRUPTIBLE instead and make sure to flush signals
before calling schedule.

27ed9ddfde bnx2: Promote vector field in bnx2_irq structure from u16 to unsigned int
The bnx2 driver stores/uses the irq value from the pci_dev internally.
But when it stores the irq value, it has been performing an
integer demotion.  Because of the recent changes made to
arch/x86/kernel/io_apic.c, the new method in creating the irq value
(using build_irq_for_pci_dev()) has exposed this bug on x86 systems.

Because of this demotion when calling request_irq() from
bnx2_request_irq(), the driver would get a return code of -EINVAL.
This is because the kernel could not find the requested irq descriptor.
By storing the irq value properly, the kernel can find the correct
irq descriptor and the bnx2 driver can operate normally.

b08508c40a PCI: fix compiler warnings in pci_get_subsys()
pci_get_subsys() changed in 2.6.26 so that the from pointer is modified
when the call is being invoked, so fix up the 'const' marking of it that
the compiler is complaining about.

e8224e4b80 IPoIB: Fix deadlock on RTNL between bcast join comp and ipoib_stop()
Taking rtnl_lock in ipoib_mcast_join_complete() causes a deadlock with
ipoib_stop().  We avoid it by scheduling the piece of code that takes
the lock on ipoib_workqueue instead of executing it directly.  This
works because we only flush the ipoib_workqueue with the RTNL not held.

The deadlock happens because ipoib_stop() calls ipoib_ib_dev_down()
which calls ipoib_mcast_dev_flush(), which calls ipoib_mcast_free(),
which calls ipoib_mcast_leave(). The latter calls
ib_sa_free_multicast(), and this waits until the multicast completion
handler finishes.  This handler is ipoib_mcast_join_complete(), which
waits for the rtnl_lock(), which was already taken by ipoib_stop().

This bug was introduced in commit a77a57a1 ("IPoIB: Fix deadlock on
RTNL in ipoib_stop()").
