Update function of_find_property() to return NULL if the device_node
passed to it is also NULL. Otherwise, passing NULL will cause a null
pointer dereference.
Without this, the legacy_serial driver will crash if there's no
'chosen' node in the device tree.

Everybody wants to pass it a function pointer, and in fact, that is what
you _must_ pass it for it to make sense (since it knows that ia64 and
ppc64 use descriptors for function pointers and fetches the actual
address from there).
So don't make the argument be a 'unsigned long' and force everybody to
add a cast.

Enabling the BKL to be lockdep tracked uncovered the following
upstream kernel bug in the tty code, which caused a BKL
reference leak:
================================================
[ BUG: lock held when returning to user space! ]
------------------------------------------------
dmesg/3121 is leaving the kernel with locks still held!
1 lock held by dmesg/3121:
#0: (kernel_mutex){--..}, at: [<c02f34d9>] opost+0x24/0x194
this might explain some of the atomicity warnings and crashes
that -tip tree testing has been experiencing since the BKL
was converted back to a spinlock.

To construct the integer containing the information from the bus_id,
it is easier to use the data from ccw_dev_id than to parse the bus_id.

When the dasd_int_handler is called with an error code instead of
an irb, the associated request should be restarted. This handling
was missing from the -ETIMEDOUT case. In fact it should be done in
any case.

As setting and clearing queue flags now requires that we hold a spinlock
on the queue, and as blk_queue_stack_limits is called without that lock,
get the lock inside blk_queue_stack_limits.
For blk_queue_stack_limits to be able to find the right lock, each md
personality needs to set q->queue_lock to point to the appropriate lock.
Those personalities which didn't previously use a spin_lock, us
q->__queue_lock. So always initialise that lock when allocated.
With this in place, setting/clearing of the QUEUE_FLAG_PLUGGED bit will no
longer cause warnings as it will be clear that the proper lock is held.
Thanks to Dan Williams for review and fixing the silly bugs.

Add a common hex array in hexdump.c so everyone can use it.
Add a common hi/lo helper to avoid the shifting masking that is

The AD181x and AZT230 chips don't support an IRQ-less MPU401 option but
work fine without one. This adds (priority functional) IRQ-less options
for each port option to help systems with few available IRQs.
The AD1815 quirk can't use pnp_register_irq_resource() due to doubly
penalizing the IRQ. Also, while not a practical issue due to no IRQ
option being present for the dependents, this needs to add in front, not
back.
Doesn't use pnp_register_port_resource() for symetry with above.
This does not delete the AD1815 independent option even though it should
be empty after the IRQ transfer due to AD1816 coming with an empty but
still present independent option by default.
Was tested on AD1815, AD1816 and AZT2320. The ALSA snd-ad1818a driver
also support the AZT2002 ID for MPU401 but this doesn't as I was unable to
test it.

The subsequent AD181x quirk patch would like this as part of the API.
pnp_register_dependent_option() adds to the same dependent chain the quirk is
walking which is fairly unclean. This enables a private option chain build
which it can then just add onto the end when done.

The following patch caused a regression with OLPC panels:
commit 3888d4639e78802c4ec1086127124e890461b9e4
lxfb: extend PLL table to support dotclocks below 25 MHz
Extends the PLL frequency table of the AMD Geode-LX frame buffer driver to
make use of the DIV4 bit, thus adding support for dotclocks between 6 and 25
MHz. These are needed for small LCDs (e.g. 320x240). Also inserts some
intermediate steps between pre-existing frequencies.
The problem was the insertion of intermediate steps into the frequency
table; they would cause the wrong frequency to be matched. This patch
drops those intermediate frequencies while keeping the sub-25MHz
frequencies.

Alignment was previously requested because cpu_buffer was an [NR_CPUS]
array, to avoid cache line sharing between CPUS.
After commit 608dfddd845da5ab6accef70154c8910529699f7 (oprofile: change
cpu_buffer from array to per_cpu variable ), we dont need to force an
alignement anymore since cpu_buffer sits in per_cpu zone.

Andrew Morton <akpm@linux-foundation.org> pointed out that bitops
should take an unsigned long * arg. However, the ipath driver was
doing bitops on struct ipath_devdata.ipath_sdma_status, which is u64.
Change this member to unsigned long to avoid tons of warnings when x86
fixes the bitops to take unsigned long * instead of void *.
Also, change the IPATH_SDMA_RUNNING and IPATH_SDMA_SHUTDOWN bit
numbers to 30 and 31 (instead of 62 and 63) so that we're not setting
another booby trap for someone who tries to make ipath work on a
32-bit architecture.

The official reason is "with the presence of pid namespaces in the
kernel using pid_t-s inside one is no longer safe."
But the reason I fix this right now is the following:
About a month ago (when 2.6.25 was not yet released) there still was a
one last caller of a to-be-deprecated-soon function find_pid() - the
kill_proc() function, which in turn was only used by nfs callback
code.
During the last merge window, this last caller was finally eliminated
by some NFS patch(es) and I was about to finally kill this kill_proc()
and find_pid(), but found, that I was late and the kill_proc is now
called from the ipath driver since commit 58411d1c ("IB/ipath: Head of
Line blocking vs forward progress of user apps").
So here's a patch that fixes this code to use struct pid * and (!)
the kill_pid routine.

The send DMA hardware queue voided a number of prior assumptions about
when a send is complete which led to completions being generated out of
order. There were also a number of locking issues when switching the QP
to the error or reset states, and we implement the IB_QPS_SQD state.

When errors are detected in RC, the QP should transition to the
IB_QPS_ERR state, not the IB_QPS_SQE state. Also, when the error is on
the responder side, the receive work completion error was incorrect
(remote vs. local).

Fix some bugs with the max_aggr module parameter added with LRO support:
- The module parameter value ignored and not actually used to set
lro_mgr.max_aggr.
- MODULE_PARM_DESC had a typo "_mro_" instead of "_lro_" so it didn't
end up describing the actual module parameter.
- The nes_lro_max_aggr variable was declared as unsigned, but the
module_param line said "int" instead of "uint" for the type.
- The default value for the parameter was stuck in the permissions
field of module_param, which led to nonsensical permissions for the
file under /sys/module/iw_nes/param.
- The parameter was used in only one file but defined in another, which
led to the variable being global for no good reason. Move everything
related to the parameter to the file nes_hw.c where it is actually
used.

The current code passes a context pointer in the xc5000_config struct.
This context pointer is used in the tuner_callback function, used to
reset the device after firmware download.
The xc5000_config struct is a static structure, whose .priv member was
being assigned before calling xc5000_attach(). If there are more than
one of the same device type installed on a single system, the last one
to assign xc5000_config.priv will "win", and all others will cease to
function properly.
This patch passes the context pointer in xc5000_attach() rather that
storing it within the static struct xc5000_config.
