The ssm2602 uses regmap for caching not soc-cache, so we need to use
regcache_sync() instead of snd_soc_cache_sync().

In the case spi_master_initialize_queue() fails, current code calls
device_unregister() before return error from spi_register_master().
However, all the drivers call spi_master_put() in the error path if
spi_register_master() fails. Thus we should call device_del() rather than
device_unregister() before return error from spi_register_master().
This also makes all the spi_register_master() error handling consistent,
because all other error paths of spi_register_master() expect drivers to
call spi_master_put() if spi_register_master() fails.

In rspi_remove(), current code dereferences rspi after spi_unregister_master(),
thus add an extra spi_master_get() call is necessary to prevent use after free.
Current code already has an extra spi_master_put() call in rspi_remove(), so
this patch just adds a spi_master_get() call rather than a spi_master_get() with
spi_master_put() calls.

I goofed when I made unshare(CLONE_NEWPID) only work in a
single-threaded process. There is no need for that requirement and in
fact I analyzied things right for setns. The hard requirement
is for tasks that share a VM to all be in the pid namespace and
we properly prevent that in do_fork.
Just to be certain I took a look through do_wait and
forget_original_parent and there are no cases that make it any harder
for children to be in the multiple pid namespaces than it is for
children to be in the same pid namespace. I also performed a check to
see if there were in uses of task->nsproxy_pid_ns I was not familiar
with, but it is only used when allocating a new pid for a new task,
and in checks to prevent craziness from happening.

By default, the pfifo_fast queue discipline has been used by default
for all devices. But we have better choices now.
This patch allow setting the default queueing discipline with sysctl.
This allows easy use of better queueing disciplines on all devices
without having to use tc qdisc scripts. It is intended to allow
an easy path for distributions to make fq_codel or sfq the default
qdisc.
This patch also makes pfifo_fast more of a first class qdisc, since
it is now possible to manually override the default and explicitly
use pfifo_fast. The behavior for systems who do not use the sysctl
is unchanged, they still get pfifo_fast
Also removes leftover random # in sysctl net core.

Since all of the memory hotplug operations have to be carried out
under device_hotplug_lock, they won't need to acquire pm_mutex if
device_hotplug_lock is held around hibernation.
For this reason, make the hibernation code acquire
device_hotplug_lock after freezing user space processes and
release it before thawing them. At the same tim drop the
lock_system_sleep() and unlock_system_sleep() calls from
lock_memory_hotplug() and unlock_memory_hotplug(), respectively.

The hibernation core uses special memory bitmaps during image
creation and restoration and traditionally those bitmaps are
allocated before freezing tasks, because in the past GFP_KERNEL
allocations might not work after all tasks had been frozen.
However, this is an anachronism, because hibernation_snapshot()
now calls hibernate_preallocate_memory() which allocates memory
for the image upfront anyway, so the memory bitmaps may be
allocated after freezing user space safely.
For this reason, move all of the create_basic_memory_bitmaps()
calls after freeze_processes() and all of the corresponding
free_basic_memory_bitmaps() calls before thaw_processes().
This will allow us to hold device_hotplug_lock around hibernation
without the need to worry about freezing issues with user space
processes attempting to acquire it via sysfs attributes after the
creation of memory bitmaps and before the freezing of tasks.

Pull networking fixes from David Miller:
1) There was a simplification in the ipv6 ndisc packet sending
attempted here, which avoided using memory accounting on the
per-netns ndisc socket for sending NDISC packets. It did fix some
important issues, but it causes regressions so it gets reverted here
too. Specifically, the problem with this change is that the IPV6
output path really depends upon there being a valid skb->sk
attached.
The reason we want to do this change in some form when we figure out
how to do it right, is that if a device goes down the ndisc_sk
socket send queue will fill up and block NDISC packets that we want
to send to other devices too. That's really bad behavior.
Hopefully Thomas can come up with a better version of this change.
2) Fix a severe TCP performance regression by reverting a change made
to dev_pick_tx() quite some time ago. From Eric Dumazet.
3) TIPC returns wrongly signed error codes, fix from Erik Hugne.
4) Fix OOPS when doing IPSEC over ipv4 tunnels due to orphaning the
skb->sk too early. Fix from Li Hongjun.
5) RAW ipv4 sockets can use the wrong routing key during lookup, from
Chris Clark.
6) Similar to #1 revert an older change that tried to use plain
alloc_skb() for SYN/ACK TCP packets, this broke the netfilter owner
mark which needs to see the skb->sk for such frames. From Phil
Oester.
7) BNX2x driver bug fixes from Ariel Elior and Yuval Mintz,

The issue is that when the task group leader of an init process exits
before other tasks of the init process when the init process finally
exits it will be a secondary task sleeping in zap_pid_ns_processes and
waiting to wake up when the number of hashed pids drops to two. This
case waits forever as free_pid only sends a wake up when the number of
hashed pids drops to 1.
To correct this the simple strategy of sending a possibly unncessary
wake up when the number of hashed pids drops to 2 is adopted.
Sending one extraneous wake up is relatively harmless, at worst we
waste a little cpu time in the rare case when a pid namespace
appropaches exiting.
We can detect the case when the pid namespace drops to just two pids
hashed race free in free_pid.
Dereferencing pid_ns->child_reaper with the pidmap_lock held is safe
without out the tasklist_lock because it is guaranteed that the
detach_pid will be called on the child_reaper before it is freed and
detach_pid calls __change_pid which calls free_pid which takes the
pidmap_lock. __change_pid only calls free_pid if this is the
last use of the pid. For a thread that is not the thread group leader
the threads pid will only ever have one user because a threads pid
is not allowed to be the pid of a process, of a process group or
a session. For a thread that is a thread group leader all of
the other threads of that process will be reaped before it is allowed
for the thread group leader to be reaped ensuring there will only
be one user of the threads pid as a process pid. Furthermore
because the thread is the init process of a pid namespace all of the
other processes in the pid namespace will have also been already freed
leading to the fact that the pid will not be used as a session pid or
a process group pid for any other running process.

Change the ordering of device hotplug locks in scan.c so that
acpi_scan_lock is always acquired after device_hotplug_lock.
This will make it possible to use device_hotplug_lock around some
code paths that acquire acpi_scan_lock safely (most importantly
system suspend and hibernation). Apart from that, acpi_scan_lock
is platform-specific and device_hotplug_lock is general, so the
new ordering appears to be more appropriate from the overall
design viewpoint.

Add support for PMC (now Chingis, part of ISSI) Pm25LV512 (512 Kib),
Pm25LV010 (1 Mib) and Pm25LQ032 (32 Mib) SPI Flash chips.
This patch addresses two generations of PMC SPI Flash chips:
- Pm25LV512 and Pm25LV010: these have 4KiB sectors and 32KiB
blocks. The 4KiB sector erase uses a non-standard opcode
(0xd7). They do not support JEDEC RDID (0x9f), and so they can only
be detected by matching their name string with pre-configured
platform data. Because of the cascaded acquisitions, the datasheet
is no longer available on the current manufacturer's website,
although it is still commonly used in some recent wireless routers
(<https://forum.openwrt.org/viewtopic.php?pid=186360#p186360>). The
only public datasheet available seems to be on GeoCities:
<http://www.geocities.jp/scottle556/pdf/Pm25LV512-010.pdf>
- Pm25LQ032: a newer generation flash, with 4KiB sectors and 64KiB
blocks. It uses the standard erase and JEDEC read-ID
opcodes. Manufacturer's datasheet is here:
<http://www.chingistek.com/img/Product_Files/Pm25LQ032C%20datasheet%20v1.6.1.pdf>
This patch is resent in order to take into account both Brian Norris

mtd: m25p80: introduce SST_WRITE flag for SST byte programming
Not all SST devices implement the SST byte programming command.
Some devices (like SST25VF064C) implement only standard m25p80 page

Now SPI flash devices that need sst_write() are explicitly marked
with new SST_WRITE flag and the decision to use sst_write() is based
on this flag instead of manufacturer id.

The tracepoint for kvm_guest_fault was extremely long, make it a
slightly bit shorter.

THe kvm_set_pte function was actually assigning the entire struct to the
structure member, which should work because the structure only has that
one member, but it is still not very nice.

Commit dc975382 "net: fec: add napi support to improve proformance"
converted the fec driver to the napi model. However, that commit
forgot to remove the call to skb_defer_rx_timestamp which is only
needed in non-napi drivers.
(The function napi_gro_receive eventually calls netif_receive_skb,
which in turn calls skb_defer_rx_timestamp.)
This patch should also be applied to the 3.9 and 3.10 kernels.

While looking into MLDv1/v2 code, I noticed that bridging code does
not convert it's max delay into jiffies for MLDv2 messages as we do
in core IPv6' multicast code.
RFC3810, 5.1.3. Maximum Response Code says:
The Maximum Response Code field specifies the maximum time allowed
before sending a responding Report. The actual time allowed, called
the Maximum Response Delay, is represented in units of milliseconds,
and is derived from the Maximum Response Code as follows: [...]
As we update timers that work with jiffies, we need to convert it.

Delete a "return" when commit the patch to a new kernel version
by mistake. So recover it.

My static checker complains that on some arches unsigned longs can be 8
characters which is larger than the buffer is only 6 chars.
Additionally, Ben Hutchings points out that the buffer actually holds
big endian data and the buffer we are reading from is CPU endian.

read beyond the end of skb->data for several bytes.

commit 8728c544a9cbdc ("net: dev_pick_tx() fix") and commit
b6fe83e9525a ("bonding: refine IFF_XMIT_DST_RELEASE capability")
are quite incompatible : Queue selection is disabled because skb
dst was dropped before entering bonding device.
This causes major performance regression, mainly because TCP packets
for a given flow can be sent to multiple queues.
This is particularly visible when using the new FQ packet scheduler
with MQ + FQ setup on the slaves.
We can safely revert the first commit now that 416186fbf8c5b
("net: Split core bits of netdev_pick_tx into __netdev_pick_tx")
properly caps the queue_index.

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly. This is a cosmetic change
