This patch implents adding/deleting mdb entries via netlink.
Currently all entries are temp, we probably need a flag to distinguish
permanent entries too.

Pull cgroup changes from Tejun Heo:
"A lot of activities on cgroup side. The big changes are focused on
making cgroup hierarchy handling saner.
- cgroup_rmdir() had peculiar semantics - it allowed cgroup
destruction to be vetoed by individual controllers and tried to
drain refcnt synchronously. The vetoing never worked properly and
caused good deal of contortions in cgroup. memcg was the last
reamining user. Michal Hocko removed the usage and cgroup_rmdir()
path has been simplified significantly. This was done in a
separate branch so that the memcg people can base further memcg
changes on top.
- The above allowed cleaning up cgroup lifecycle management and
implementation of generic cgroup iterators which are used to
improve hierarchy support.
- cgroup_freezer updated to allow migration in and out of a frozen
cgroup and handle hierarchy. If a cgroup is frozen, all descendant
cgroups are frozen.
- netcls_cgroup and netprio_cgroup updated to handle hierarchy
properly.
- Various fixes and cleanups.
- Two merge commits. One to pull in memcg and rmdir cleanups (needed
to build iterators). The other pulled in cgroup/for-3.7-fixes for
device_cgroup fixes so that further device_cgroup patches can be
stacked on top."

- Allow drivers to get the irqdomain for regmap irq_chips, allowing the
domain to be used with other APIs.
- Debug improvements for paged register maps.
- Performance improvments for some of the diagnostic infrastructure,
very helpful for devices with large register maps.

The debug polling interface for the SoC serial ports did not work in the case
where the serial ports were not also used as a console. In that case, the
uart driver startup function will not be called so tx and rx would not be
enabled in the hardware control register. Also, vdma interrupts would not be
enabled which the poll_get_char function relied on. This patch makes sure that
the rx and tx enables are set as a consequence of the uart set_termios call
which is the only initialization done for the debug polling interface. Also,
the poll_get_char now handles the case where vdma interrupts are not enabled.

The SoC serial port driver uses a high priority interrupt to handle tx of
characters in the tx ring buffer. The driver needs to disable/enable this IRQ
from outside of irq context. The original code to do this is not foolproof on
SMP machines because the IRQ running on one core could still access the serial
port for a short time after the driver running on another core disables the
interrupt. This patch adds a flag to tell the IRQ handler that the driver
wants to disable the interrupt. After seeing the flag, the IRQ handler will
immediately disable the interrupt and exit. After setting the flag, the driver
will wait for interrupt to be disabled by the IRQ handler.

The builtin SoC serial ports have no FIFOs and use a virtual DMA mechanism
based on high priority IRQs to avoid overruns. These high priority interrupts
are pinned to cpu#0 on SMP systems. This patch fixes a problem with SMP where
the set_intr_level() interface is used to set the priority for these IRQs. The
set_intr_level() function sets priority on the local cpu but on SMP systems,
this code may be run on some other cpu than the one handling the interrupts.
Instead of setting interrupt level explicitly, this patch uses a special
irq_chip for these interrupts so that the mask/unmask methods can set the
interrupt level implicitly.

The irq_set_affinity handler for the mn10300 cpu pic had some hard-coded IRQs
which were not to be migrated from one cpu to another. This patch cleans those
up by using a combination of IRQF_NOBALANCING and specialized irq chips with
no irq_set_affinity handler. This maintains the previous behavior by using
generic IRQ interfaces rather than hard coding IRQ numbers in the default
irq_set_affinity handler.

Pull ARM OMAP serial updates from Russell King:
"This series is a major reworking of the OMAP serial driver code fixing
various bugs in the hardware-assisted flow control, extending up into
serial_core for a couple of issues. These fixes have been done as a
set of progressive changes and transformations in the hope that no new
bugs will be introduced by this series.
The problems are many-fold, from the driver not being informed about
updated settings, to the driver not knowing what the intentions of the
upper layers are.
The first four patches tackle the serial_core layer, allowing it to
provide the necessary information to drivers, and the remaining
patches allow the OMAP serial driver to take advantage of this.
This brings hardware assisted RTS/CTS and XON/OFF flow control into a
useful state.
These patches have been in linux-next for most of the last cycle;
indeed they predate the previous merge window. They've also been
posted to the OMAP people."

The runtime_idle callback is the right place to check the suspend
capability, but currently we do it wrongly in the runtime_suspend
callback. This leads to a kernel error message like:
pci_pm_runtime_suspend(): azx_runtime_suspend+0x0/0x50 [snd_hda_intel] returns -11
and the runtime PM core would even repeat the attempts.

The HD-audio driver artificially calls the suspend and the resume code
path in the VGA switcheroo state changes. When a machine goes to
suspend, it tries to suspend the device again, and it stalls at
snd_power_wait().
This patch adds checks whether the devices were already in (forced)
suspend in PM callbacks for avoiding the doubly suspend.

When the HD-audio controller is disabled (e.g. via vga switcheroo) but
the driver is still accessing it, it spews floods of "spurious
response" kernel messages. It's because CORB/RIRB WP reads 0xff, and
the driver tries to fill up until this number.
This patch changes the CORB/RIRB WP reads to word instead of byte, and
add the check of the read value. If it's 0xffff, the controller is
supposed to be disabled, so the further action will be skipped.

With BQL being deployed, we can more likely have following behavior :
We dequeue a packet from qdisc in dequeue_skb(), then we realize target
tx queue is in XOFF state in sch_direct_xmit(), and we have to hold the
skb into gso_skb for later.
This shows in stats (tc -s qdisc dev eth0) as requeues.
Problem of these requeues is that high priority packets can not be
dequeued as long as this (possibly low prio and big TSO packet) is not
removed from gso_skb.
At 1Gbps speed, a full size TSO packet is 500 us of extra latency.
In some cases, we know that all packets dequeued from a qdisc are
for a particular and known txq :
- If device is non multi queue
- For all MQ/MQPRIO slave qdiscs
This patch introduces a new qdisc flag, TCQ_F_ONETXQUEUE to mark
this capability, so that dequeue_skb() is allowed to dequeue a packet
only if the associated txq is not stopped.
This indeed reduce latencies for high prio packets (or improve fairness
with sfq/fq_codel), and almost remove qdisc 'requeues'.

We weren't clearing card->tx_skb[port] when processing the TX done interrupt.
If there wasn't another skb ready to transmit immediately, this led to a
double-free because we'd free it *again* next time we did have a packet to
send.

Pull x86 BSP hotplug changes from Ingo Molnar:
"This tree enables CPU#0 (the boot processor) to be onlined/offlined on

Allowing this required the identification and fixing of latent CPU#0
assumptions (such as CPU#0 initializations, etc.) in the x86
architecture code, plus the identification of barriers to
BSP-offlining, such as active PIC interrupts which can only be
serviced on the BSP.
It's behind a default-off option, and there's a debug option that
allows the automatic testing of this feature.
The motivation of this feature is to allow and prepare for true
CPU-hotplug hardware support: recent changes to MCE support enable us
to detect a deteriorating but not yet hard-failing L1/L2 cache on a
CPU that could be soft-unplugged - or a failing L3 cache on a
multi-socket system.
Note that true hardware hot-plug is not yet fully enabled by this,
because that requires a special platform wakeup sequence to be sent to
the freshly powered up CPU#0. Future patches for this are planned,
once such a platform exists. Chicken and egg"
