Commit 63779436 ("drivers: replace NIPQUAD()") accidentally replaced
some HIPQUAD()s, causing IP addresses to be printed in reverse order.
Add temporary local vars until the byteswapping can be pushed further
up the stack.

If the mlx4_ib driver finds an adapter that has only ethernet ports, the
current code will register an IB device with 0 ports. Nothing useful or
sensible can be done with such a device, so just skip registering it.

Recent cpumask changes changed num_possible_cpus() from returning an int
to returning an unsigned int. This means that doing
min(num_possible_cpus(), <int expression>)
now produces a warning like
drivers/net/mlx4/main.c: In function 'mlx4_enable_msi_x':
drivers/net/mlx4/main.c:915: warning: comparison of distinct pointer types lacks a cast
Fix this by using min_t(int, ...).

Because the ipoib_workqueue is not flushed when ipoib interface is
brought down, ipoib_mcast_join() may trigger a join to the broadcast
group after priv->broadcast was set to NULL (during cleanup). This
will cause the system to be a member of the broadcast group when
interface is down. As a side effect, this breaks the optimization of
setting the Q_key only when joining the broadcast group.

Fix bonding failover in the case both peers failover and the
gratuitous ARP is lost. In that case, the sender side will create an
ipoib_neigh and issue a path request with the old GID first. When
skb->dst->neighbour->ha changes due to ARP refresh, this ipoib_neigh
will not be added to the path->list of the path of the new GID,
because the ipoib_neigh already exists. It will not have an AH
either, because of sender-side failover. Therefore, it will not get
an AH when the path is resolved.
The solution here is to compare GIDs in ipoib_start_xmit() even if
neigh->ah is invalid. Comparing with an uninitialized value of
neigh->dgid should be fine, since a spurious match is harmless (and
astronomically unlikely too).

At 37000 feet somewhere near Greenland I woke up from a half-sleep with the
realisation that __lowest_in_progress() is buggy. After landing I checked
and there were indeed 2 problems with it; this patch fixes both:
* The order of the list checks was wrong
* The locking was not correct.

There has been some light flamewar on lkml about decoding oopses
in modules (as part of the crashdump flamewar).
Now this isn't rocket science, just the markup_oops.pl script
cheaped out and didn't handle modules. But really; a flamewar
all about that?? What happened to C++ in the kernel or reading
files from inside the kernel?
This patch adds module support to markup_oops.pl; it's not the
most pretty perl but it works for my testcases...

struct sched_domain is now a dangling structure; where we really want

(As the FIXME in this file says, cpumask_var_t would be better, but
this code is hairy enough without trying to add initialization code to
the right places).

If you do
smp_call_function_single(expression-with-side-effects, ...)
then expression-with-side-effects never gets evaluated on UP builds.
As always, implementing it in C is the correct thing to do.
While we're there, uninline it for size and possible header dependency
reasons.
And create a new kernel/up.c, as a place in which to put
uniprocessor-specific code and storage. It should mirror kernel/smp.c.

This patch fixes an rcutorture bug found by Eric Sesterhenn that
resulted in oopses in response to "rmmod rcutorture". The problem
was in some new code that attempted to handle the case where a system
is shut down while rcutorture is still running, for example, when
rcutorture is built into the kernel so that it cannot be removed.
The fix causes the rcutorture threads to "park" in an
schedule_timeout_uninterruptible(MAX_SCHEDULE_TIMEOUT) rather than
trying to get them to terminate cleanly. Concurrent shutdown and
rmmod is illegal.
I believe that this is 2.6.29 material, as it is used in some testing
setups.
For reference, here are the rcutorture operating modes:
CONFIG_RCU_TORTURE_TEST=m
This is the normal rcutorture build. Use "modprobe rcutorture"
(with optional arguments) to start, and "rmmod rcutorture" to
stop. If you shut the system down without doing the rmmod, you
should see console output like:
rcutorture thread rcu_torture_writer parking due to system shutdown
One for each rcutorture kthread.
CONFIG_RCU_TORTURE_TEST=y
CONFIG_RCU_TORTURE_TEST_RUNNABLE=n
Use this if you want rcutorture built in, but don't want the
test to start running during early boot. To start the
torturing:
echo 1 > /proc/sys/kernel/rcutorture_runnable
To stop the torturing, s/1/0/
You will get "parking" console messages as noted above when
you shut the system down.
CONFIG_RCU_TORTURE_TEST=y
CONFIG_RCU_TORTURE_TEST_RUNNABLE=y
Same as above, except that the torturing starts during early
boot. Only for the stout of heart and strong of stomach.
The same /proc entry noted above may be used to control the
test.

This patch adds basic support for the PCF50633 ADC. The subtractive mode
is not supported yet.
Since we don't have adc subsystem, it currently lives in drivers/mfd.

This patch implements the core of the PCF50633 driver. This core driver has
generic register read/write functions and does interrupt management for its
sub devices.

Replace the current sysctl-based suspend interface with a new sysfs-
based one which also uses the Linux-2.6 suspend model.
To configure wakeup sources, a subtree for the demoboards is created
under /sys/power/db1x:
sys/
`-- power
`-- db1x
|-- gpio0
|-- gpio1
|-- gpio2
|-- gpio3
|-- gpio4
|-- gpio5
|-- gpio6
|-- gpio7
|-- timer
|-- timer_timeout
|-- wakemsk
`-- wakesrc
The nodes 'gpio[0-7]' and 'timer' configure the GPIO0..7 and M2
bits of the SYS_WAKEMSK (wakeup source enable) register. Writing '1'
enables a wakesource, 0 disables it.
The 'timer_timeout' node holds the timeout in seconds after which the
TOYMATCH2 event should wake the system.
The 'wakesrc' node holds the SYS_WAKESRC register after wakeup (in hex),
the 'wakemsk' node can be used to get/set the wakeup mask directly.
For example, to have the timer wake the system after 10 seconds of sleep,
the following must be done in userspace:
echo 10 > /sys/power/db1x/timer_timeout
echo 1 > /sys/power/db1x/timer
echo mem > /sys/power/sleep
This patch also removes the homebrew CPU frequency switching code. I don't
understand how it could have ever worked reliably; it does not communicate
the clock changes to peripheral devices other than uarts.

Au1550/Au1200 have a different memory controller which requires additi-
onal code to properly put memory to sleep (code taken from AMD/RMI's
Linux-2.6.11 source package).
Also fix up the remaining pm-related paths to compile on Au1200/Au1550
platforms.

Now that nothing in time.c depends on calc_clock, it can
be moved to clocks.c where it belongs.
While at it, give it a better non-generic name and call it
as soon as possible in plat_mem_init.

Add support for the 32 kHz counter1 (RTC) as clocksource / clockevent
device. As a nice side effect, this also enables use of the 'wait'
instruction for runtime idle power savings.
If the counters aren't enabled/working properly, fall back on the
cp0 counter clock code.
