Pull core locking updates from Ingo Molnar:
"The main changes in this cycle were:
- reduced/streamlined smp_mb__*() interface that allows more usecases
and makes the existing ones less buggy, especially in rarer
architectures
- add rwsem implementation comments
- bump up lockdep limits"
* 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (33 commits)
rwsem: Add comments to explain the meaning of the rwsem's count field

w1_process_callbacks() expects to be called with dev->list_mutex held,
but it is the fact only in w1_process(). __w1_remove_master_device()
calls w1_process_callbacks() after it releases list_mutex.
The patch fixes __w1_remove_master_device() to acquire list_mutex
for w1_process_callbacks().

Applications can submit a set of commands in one packet to the kernel,
and in some cases it is required such as reading the temperature
sensor results. This adds an option W1_CN_BUNDLE to the flags of
cn_msg to request the kernel to reply in one packet for efficiency.
The cn_msg flags now check for unknown flag values and return an error
if one is seen. See "Proper handling of unknown flags in system
calls" http://lwn.net/Articles/588444/
This corrects the ack values returned as per the protocol standard,
namely the original ack for status messages and seq + 1 for all others
such as the data returned from a read.
Some of the common variable names have been standardized as follows.
struct cn_msg *cn
struct w1_netlink_msg *msg
struct w1_netlink_cmd *cmd
struct w1_master *dev
When an argument and a function scope variable would collide, add req_
to the argument.

__w1_attach_slave_device calls device_add which calls w1_bus_notify
which calls the w1_bq27000 slave driver, which calls
platform_device_add and device_add and deadlocks on getting
&(&priv->bus_notifier)->rwsem as it is still held in the previous
device_add. This avoids the problem by processing the family
add/remove outside of the slave device_add call.
Commit 47eba33a0997fc7362a introduced this deadlock and added
a KOBJ_ADD, as the add was already reported in device_register two add
events were being sent. This change suppresses the device_register
add so that any slave device sysfs entries are setup before the add
goes out.
Belisko Marek reported this change fixed the deadlock he was seeing on
ARM device tree, while testing on my x86-64 system never saw the
deadlock.

If the message type is W1_MASTER_CMD or W1_SLAVE_CMD, then a reference
is taken when searching for the slave or master device. If there
isn't any following data m->len (mlen is a copy) is 0 and packing up
the message for later execution is skipped leaving nothing to
decrement the reference counts.
Way back when, m->len was checked before the search that increments the
reference count, but W1_LIST_MASTERS has no additional data, the check
was moved in 9be62e0b2fadaf5ff causing this bug.
This change reorders to put the check before the reference count is
incremented avoiding the problem.

of_get_gpio() might return -EPROBE_DEFER meaning that the driver
providing the gpio isn't ready yet. If that happens for the first gpio
the resulting kernel output without this patch is:
w1-gpio somename: Failed to parse DT
platform somename: Driver w1-gpio requests probe deferral
The first message is misleading and so is suppressed with this patch.
Further if determining the gpio to switch the external pullup yields
-EPROBE_DEFER this error should be passed back to the caller instead of
just continuing without pullup.

On 64 bit systems, a large value for "long tmp" is truncated when
assigning to "int md->max_slave_count" so we still end up with a value
less than one despite the "tmp < 1" check.

The bus_mutex needs to be taken to serialize access to a specific bus.
netlink wasn't updated when bus_mutex was added and was calling
without that lock held, and not all of the masters were holding the
bus_mutex in a search. This was causing the ds2490 hardware to stop
responding when both netlink and /sys slaves were executing bus
commands at the same time.

The first line printed from w1_slave gives the context of the w1
device. So does the second line, but if the CRC check failed, the
second line contains the last successful result. It is confusing when
it prints the temperature next to the line that might be a previous
conversion and has nothing to do with that printed temperature value.
Modify the code to store the last good conversion in family_data,
which is designed for custom data structures.

alt 0 or 1, 10ms int, 23.16 seconds

Introduce new commands to add, remove, and list slave devices through
the netlink interface. This can be useful to skip the search on a
static network. They could previously only be added or removed
through automatic search or sysfs, and this allows a program to only
use netlink.
Only allocate memory when needed, so move kzalloc into w1_get_slaves

w1_max_slave_count is only used to abort the search early
or take a fast search (when 1), so there isn't any reason to not allow
it to be updated through sysfs. Memory is not allocated based on
the current value and 10 is a rather low base number, increasing to
64, and printing a message the first time the count is reached and
there were more devices to discover to let the user know why not
all the devices were found.

Before 63706172f33 "rework kthread_stop()" kthread_should_stop()
always returned false when called from a non-kthread task, after it
would oops as a non-kthread didn't have that structure and netlink was
calling search from a thread which wasn't a kthread. 9d1817cab2f030
"w1: fix oops when w1_search is called from netlink connector",
modified the code to avoid calling kthread_stop from a netlink thread.
Introduce a w1_master flag and bit W1_ABORT_SEARCH to identify abort
to cleanly support both kthread and netlink search abort. A search
can take seconds to run, so it is important to abort early if the
hardware is removed in the middle of a search.

Previous logic,
if (avail > 8) {
store slave;
return;
}
send data; clear;
The logic error is, if there isn't space send the buffer and clear,
but the slave wasn't added to the now empty buffer loosing that slave
id. It also should have been "if (avail >= 8)" because when it is 8,
there is space.
Instead, if there isn't space send and clear the buffer, then there is
always space for the slave id.

On architectures where long is more then 32 bits, modifying a 32-bit field
with set_bit (and other atomic bit operations) may cause bytes following
the field to by modified.
Because the endianness of the bits within a field is the native endianness
of the CPU[1], on big-endian machines, bit number zero is in the last byte
of the field.
Therefore, `set_bit(0, ptr)' on a 64-bit big-endian machine is roughly
equivalent to `((char *)ptr)[7] |= 1', and since w1 driver uses a 32-bit
field for holding the flags, this causes bytes beyond the field to be
modified.
[1] From Documentation/atomic_ops.txt:
Native atomic bit operations are defined to operate on objects
aligned to the size of an "unsigned long" C data type, and are
least of that size. The endianness of the bits within each
"unsigned long" are the native endianness of the cpu.
