"omap: iovmm: don't check 'da' to set IOVMF_DA_FIXED flag",
changes iovmm to receive flags specified by user, however
the upper 16 bits of the flags are wiped by iovmm itself.
This fixes IOVMF_DA_FIXED flags from being lost, and lets the user
map its desired "device addresses".

The current code takes an unaligned pointer and does htonl() on it to
make it big-endian, then does a memcpy(). The problem is that the
compiler decides that since the pointer is to a __be32, it is legal
to optimize the copy into a processor word store. However, on an
architecture that does not handled unaligned writes in kernel space,
this produces an unaligned exception fault.
The solution is to track the pointer as a "char *" (which removes a bunch
of unpleasant casts in any case), and then just use put_unaligned_be32()
to write the value to memory.

IO_SPACE_LIMIT is currently used in two ways:
1) As a way to mask I/O port values read out of PCI base address
registers. This value should be 64-bit.
2) As a value which is the upper limit for all I/O "ports" in the
system.
On sparc64 we store the full 64-bit physical I/O address in the
resources. For this reason we define IO_SPACE_LIMIT at a 64-bit
"all 1's".
This is the right value to use for ioport_resource.end and for the
check made in drivers/pcmcia/rsrc_nonstatic.c:adjust_io().
But in driver/pci/probe.c:__pci_read_base() we mask this against
a "u32" variable and thus get the following warning:
drivers/pci/probe.c: In function ¡__pci_read_base¢:
drivers/pci/probe.c:207: warning: large integer implicitly truncated to unsigned type
Fix this by using an explicit "u32" cast.
I considered changing sparc64 to define a 32-bit "all 1's" like
most other systems do, but this wouldn't work because the checks
in PCMCIA's rsrc_nonstatic.c would no longer be right since they
are testing against fully formed 64-bit resources. As described
above, on sparc64 such resources will hold full 64-bit physical
I/O addresses, not bus-centric 32-bit ones.

zd1211 devices register 'EP 4 OUT' endpoint as Interrupt type on USB 2.0:
Endpoint Descriptor:

bDescriptorType 5
bEndpointAddress 0x04 EP 4 OUT
bmAttributes 3
Transfer Type Interrupt
Synch Type None
Usage Type Data
wMaxPacketSize 0x0040 1x 64 bytes

However on USB 1.1 endpoint becomes Bulk:
Endpoint Descriptor:
bLength 7
bDescriptorType 5
bEndpointAddress 0x04 EP 4 OUT
bmAttributes 2
Transfer Type Bulk
Synch Type None
Usage Type Data
wMaxPacketSize 0x0040 1x 64 bytes
bInterval 0
Commit 37939810b9 assumed that endpoint is
always interrupt type and changed usb_bulk_msg() calls to usb_interrupt_msg().
Problem here is that usb_bulk_msg() on interrupt endpoint selfcorrects the
call and changes requested pipe to interrupt type (see usb_bulk_msg).
However with usb_interrupt_msg() on bulk endpoint does not correct the
pipe type to bulk, but instead URB is submitted with interrupt type pipe.
So pre-2.6.39 used usb_bulk_msg() and therefore worked with both endpoint
types, however in 2.6.39 usb_interrupt_msg() with bulk endpoint causes
ohci_hcd to fail submitted URB instantly with -ENOSPC and preventing zd1211rw
from working with OHCI.
Fix this by detecting endpoint type and using correct endpoint/pipe types
for URB. Also fix asynchronous zd_usb_iowrite16v_async() to use right
URB type on 'EP 4 OUT'.

Fix kernel oops when trying to use passive scheduled scans. The
reason was that in passive scans there are no SSIDs, so there was a
NULL pointer dereference.
To solve the problem, we now check the number of SSIDs provided in the
sched_scan request and only access the list if there's one or more
(ie. passive scan is not forced). We also force all the channels to
be passive by adding the IEEE80211_CHAN_PASSIVE_SCAN flag locally
before the checks in the wl1271_scan_get_sched_scan_channels()

Before this patch, the command sequence number is being set before

It currently does this without considering that sequence numbers might need

we're actually submitting the command to the hardware. Also fixes a

This fixes the A->B/B->A locking dependency, see the warning below.
The function task_exit_notify() is called with (task_exit_notifier)
.rwsem set and then calls sync_buffer() which locks buffer_mutex. In
sync_start() the buffer_mutex was set to prevent notifier functions to
be started before sync_start() is finished. But when registering the
notifier, (task_exit_notifier).rwsem is locked too, but now in
different order than in sync_buffer(). In theory this causes a locking
dependency, what does not occur in practice since task_exit_notify()
is always called after the notifier is registered which means the lock
is already released.
However, after checking the notifier functions it turned out the
buffer_mutex in sync_start() is unnecessary. This is because
sync_buffer() may be called from the notifiers even if sync_start()
did not finish yet, the buffers are already allocated but empty. No
need to protect this with the mutex.
So we fix this theoretical locking dependency by removing buffer_mutex
in sync_start(). This is similar to the implementation before commit:
750d857 oprofile: fix crash when accessing freed task structs
which introduced the locking dependency.

Ben changed the cgroup API in commit f780bdb7c1 (cgroups: add
per-thread subsystem callbacks) in an incompatible way, but
forgot to convert the perf cgroup bits.
Avoid compile warnings and runtime splats and convert perf too ;-)

While looking over the code I found that with the ttwu rework the
nr_wakeups_migrate test broke since we now switch cpus prior to
calling ttwu_stat(), hence the test is always true.
Cure this by passing the migration state in wake_flags. Also move the
whole test under CONFIG_SMP, its hard to migrate tasks on UP :-)

Markus reported that commit 317f394160 ("sched: Move the second half
of ttwu() to the remote cpu") caused some accounting funnies on his AMD
Phenom II X4, such as weird 'top' results.
It turns out that this is due to non-synced TSC and the queued remote
wakeups stopped coupeling the two relevant cpu clocks, which leads to
wakeups seeing time jumps, which in turn lead to skewed runtime stats.
Add an explicit call to sched_clock_cpu() to couple the per-cpu clocks
to restore the normal flow of time.

Since those defined functions require additional semicolon
from the caller, they could cause potential syntax errors
when used in if-else statements.

anything with an MPIC will crash on suspend if we register those

Commit cc3ce5176d (rcu: Start RCU kthreads in TASK_INTERRUPTIBLE
state) fudges a sleeping task' state, resulting in the scheduler seeing
a TASK_UNINTERRUPTIBLE task going to sleep, but a TASK_INTERRUPTIBLE
task waking up. The result is unbalanced load calculation.
The problem that patch tried to address is that the RCU threads could
stay in UNINTERRUPTIBLE state for quite a while and triggering the hung
task detector due to on-demand wake-ups.
Cure the problem differently by always giving the tasks at least one
wake-up once the CPU is fully up and running, this will kick them out of
the initial UNINTERRUPTIBLE state and into the regular INTERRUPTIBLE
wait state.
[ The alternative would be teaching kthread_create() to start threads as
INTERRUPTIBLE but that needs a tad more thought. ]

This reverts commit 1b842e91fe.
There is a fundamental ordering race between the early and late probe
paths and the runtime PM tie-in that results in __pm_runtime_resume()
attempting to take a lock that hasn't been initialized yet (which by
proxy also suggests that pm_runtime_init() hasn't yet been run on the
device either, making the entire thing unsafe) -- resulting in instant
death on SMP or on UP with spinlock debugging enabled:
sh_tmu.0: used for clock events
sh_tmu.0: used for periodic clock events
BUG: spinlock trylock failure on UP on CPU#0, swapper/0
lock: 804db198, .magic: 00000000, .owner: <none>/-1, .owner_cpu: 0
...
Revert it for now until the ordering issues can be resolved, or we can get
some more help from the runtime PM framework to make this possible.
