Ingo Molnar adac166523 [PATCH] rcu_torture_lock deadlock fix
rcu_torture_lock is used in a softirq-unsafe manner, but it is also
taken by rcu_torture_cb(), which may execute in softirq-context,
resulting in potential deadlocks.

The fix is to acquire rcu_torture_lock in a softirq-safe manner.  With
this fix applied, the rcu-torture code passes validation.

Ingo Molnar f6bc2666ed [PATCH] fix deadlock in drivers/pci/msi.c
The lock validator caught another one: drivers/pci/msi.c is accessing
&irq_desc[i].lock with interrupts enabled (!).

The fix is to disable interrupts properly.

Ingo Molnar 4021cb279a [PATCH] fix uidhash_lock <-> RCU deadlock
RCU task-struct freeing can call free_uid(), which is taking
uidhash_lock - while other users of uidhash_lock are softirq-unsafe.

The fix is to always take the uidhash_spinlock in a softirq-safe manner.

Michael S. Tsirkin e3aa31c517 IB/mthca: Don't cancel commands on a signal
We have run into the following problem: if a task receives a signal
while in the process of e.g. destroying a resource (which could be
because the relevant file was closed) mthca could bail out from trying
to take a command interface semaphore without performing the
appropriate command to tell hardware that the resource is being
destroyed.

As a result we see messages like
 ib_mthca 0000:04:00.0: HW2SW_CQ failed (-4)

In this case, hardware could access the resource after the memory has
been freed, possibly causing memory corruption.

A simple solution is to replace down_interruptible() by down() in
command interface activation.

Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il>
[ It's also not safe to bail out on multicast table operations, since
  they may be invoked on the cleanup path too.  So use down() for
  mcg_table.sem too. ]

Zhu Yi b6e4da7234 [PATCH] ipw2100: Fix setting txpower failed problem
The ipw2100 driver misunderstood the parameter of txpower.
Tx Power off means turn off the radio, but the driver interpret it as
"can't set txpower". So when getting the txpower, it sets disabled=1 to
the iwconifg tool in managed mode. And the tool will display "Tx Power off"
when disabled=1.

Now, in managed mode, iwconfig will not show "TX Power" if the radio is not
switched off. It will only display "Tx Power off" only if the radio is killed.
