This patch introduces 'bind_deactivated' flag in struct usb_function.
Functions which don't want to be activated automatically after bind should
set this flag, and when they start to be ready to work they should call
usb_function_activate().
When USB function sets 'bind_deactivated' flag, initial deactivation
counter is incremented automatically, so there is no need to call
usb_function_deactivate() in function bind.

Since the hardware sometimes mysteriously totally flummoxes the 64bit
read of a 64bit register when read using a single instruction, split the
read into two instructions. Since the read here is of automatically
incrementing timestamp counters, we also have to be very careful in
order to make sure that it does not increment between the two
instructions.
However, since userspace tried to workaround this issue and so enshrined
this ABI for a broken hardware read and in the process neglected that
the read only fails in some environments, we have to introduce a new
uABI flag for userspace to request the 2x32 bit accurate read of the
timestamp.
v2: Fix alignment check and include details of the workaround for
userspace.

Merge tag 'mac80211-for-davem-2015-07-17' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211
Johannes Berg says:
====================
Some fixes for the current cycle:
1. Arik introduced an rtnl-locked regulatory API to be able
to differentiate between place do/don't have the RTNL;
this fixes missing locking in some of the code paths
2. Two small mesh bugfixes from Bob, one to avoid treating
a certain malformed over-the-air frame and one to avoid
sending a garbage field over the air.
3. A fix for powersave during WoWLAN suspend from Krishna Chaitanya.
4. A fix for a powersave vs. aggregation teardown race, from Michal.
5. Thomas reduced the loglevel of CRDA messages to avoid spamming
the kernel log with mostly irrelevant information.
6. Tom fixed a dangling debugfs directory pointer that could cause
crashes if subsequent addition of the same interface to debugfs
failed for some reason.
7. A fix from myself for a list corruption issue in mac80211 during
combined interface shutdown/removal - shut down interfaces first
and only then remove them to avoid that.

Pull x86 fixes from Ingo Molnar:
"Two families of fixes:
- Fix an FPU context related boot crash on newer x86 hardware with
larger context sizes than what most people test. To fix this
without ugly kludges or extensive reverts we had to touch core task
allocator, to allow x86 to determine the task size dynamically, at
boot time.
I've tested it on a number of x86 platforms, and I cross-built it
to a handful of architectures:
(warns) (warns)
testing x86-64: -git: pass ( 0), -tip: pass ( 0)
testing x86-32: -git: pass ( 0), -tip: pass ( 0)
testing arm: -git: pass ( 1359), -tip: pass ( 1359)
testing cris: -git: pass ( 1031), -tip: pass ( 1031)
testing m32r: -git: pass ( 1135), -tip: pass ( 1135)
testing m68k: -git: pass ( 1471), -tip: pass ( 1471)
testing mips: -git: pass ( 1162), -tip: pass ( 1162)
testing mn10300: -git: pass ( 1058), -tip: pass ( 1058)
testing parisc: -git: pass ( 1846), -tip: pass ( 1846)
testing sparc: -git: pass ( 1185), -tip: pass ( 1185)
... so I hope the cross-arch impact 'none', as intended.

The FPU rewrite removed the dynamic allocations of 'struct fpu'.
But, this potentially wastes massive amounts of memory (2k per
task on systems that do not have AVX-512 for instance).
Instead of having a separate slab, this patch just appends the
space that we need to the 'task_struct' which we dynamically
allocate already. This saves from doing an extra slab
allocation at fork().
The only real downside here is that we have to stick everything
and the end of the task_struct. But, I think the
BUILD_BUG_ON()s I stuck in there should keep that from being too
fragile.

Currently, we set wrong gfp_mask to page_owner info in case of isolated
freepage by compaction and split page. It causes incorrect mixed
pageblock report that we can get from '/proc/pagetypeinfo'. This metric
is really useful to measure fragmentation effect so should be accurate.
This patch fixes it by setting correct information.
Without this patch, after kernel build workload is finished, number of
mixed pageblock is 112 among roughly 210 movable pageblocks.
But, with this fix, output shows that mixed pageblock is just 57.

Commit 2ae416b142 ("mm: new mm hook framework") introduced an empty
header file (mm-arch-hooks.h) for every architecture, even those which
doesn't need to define mm hooks.
As suggested by Geert Uytterhoeven, this could be cleaned through the use
of a generic header file included via each per architecture
asm/include/Kbuild file.
The PowerPC architecture is not impacted here since this architecture has
to defined the arch_remap MM hook.

Using __printf attributes helps to detect several format string issues
at compile time (even though -Wformat-security is currently disabled in
Makefile). For example it can detect when formatting a pointer as a
number, like the issue fixed in commit a3fa71c40f ("wl18xx: show
rx_frames_per_rates as an array as it really is"), or when the arguments
do not match the format string, c.f. for example commit 5ce1aca814
("reiserfs: fix __RASSERT format string").
To prevent similar bugs in the future, add a __printf attribute to every
function prototype which needs one in include/linux/ and lib/. These
functions were mostly found by using gcc's -Wsuggest-attribute=format
flag.

work for 4.3-rc1 will be exposed to the ever so slightly stricter (but
sensible) requirements wrt. whether they are needing init.h vs.
module.h macros, even if they are not using linux-next.
The diffstat of the move is slightly asymmetrical due to needing to
leave behind a couple #ifdef in the old location and add the same ones
to the new location, but other than that, it is a 1:1 move, complete
with the module_init/exit trailing semicolon that we can't fix. That
is, until/unless someone does a tree-wide sed fix of all the
approximately 800 currently in tree users relying on it"
* tag 'module-final-v4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux:
module: relocate module_init from init.h to module.h
Since no longer limiting max_sectors to BLK_DEF_MAX_SECTORS (commit 34b48db66e),
data corruption may occur on ST380013AS drive configured on 82801JI (ICH10 Family)
SATA controller. This patch will allow the driver to limit max_sectors as before
# cat /sys/block/sdb/queue/max_sectors_kb
512
I was able to double the max_sectors_kb value up to 16384 on linux-4.2.0-rc2
before seeing corruption, but seems safer to use previous limit. Without this
patch max_sectors_kb will be 32767.

The memory error record structure includes as its first field a
bitmask of which subsequent fields are valid. The allows new fields
to be added to the structure while keeping compatibility with older
software that parses these records. This mechanism was used between
versions 2.2 and 2.3 to add four new fields, growing the size of the
structure from 73 bytes to 80. But Linux just added all the new
fields so this test:
if (gdata->error_data_length >= sizeof(*mem_err))
cper_print_mem(newpfx, mem_err);
else
goto err_section_too_small;
now make Linux complain about old format records being too short.
Add a definition for the old format of the structure and use that
for the minimum size check. Pass the actual size to cper_print_mem()
so it can sanity check the validation_bits field to ensure that if
a BIOS using the old format sets bits as if it were new, we won't
access fields beyond the end of the structure.

We might return res which is not initialized. Also
reduce code duplication by exporting srp_parse_tmo so
srp_tmo_set can reuse it.

Persuant to Liran's comments on node_type on linux-rdma
mailing list:
In an effort to reform the RDMA core and ULPs to minimize use of
node_type in struct ib_device, an additional bit is added to
struct ib_device for is_switch (IB switch). This is needed
to be initialized by any IB switch device driver. This is a
NEW requirement on such device drivers which are all
"out of tree".
In addition, an ib_switch helper was added to ib_verbs.h
based on the is_switch device bit rather than node_type
(although those should be consistent).
The RDMA core (MAD, SMI, agent, sa_query, multicast, sysfs)
as well as (IPoIB and SRP) ULPs are updated where
appropriate to use this new helper. In some cases,
the helper is now used under the covers of using
rdma_[start end]_port rather than the open coding
previously used.

* Fix a regression in hid sensors suspend time as a result of adding runtime
pm. The normal flow of waking up devices in order to go into suspend
(given the devices are normally suspended when not reading) to a regression
in suspend time on some laptops (reports of an additional 8 seconds).
Fix this by checking to see if a user action resulting in the wake up, and
make it a null operation if it didn't. Note that for hid sensors, there is
nothing useful to be done when moving into a full suspend from a runtime
suspend so they might as well be left alone.

the driver does not taint the kernel incorrectly and can build as a module.
