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.

This increases the amount of bundling to reduce the number of packets
sent. For the one wire use there can be multiple struct
w1_netlink_cmd in a struct w1_netlink_msg and multiple of those in
struct cn_msg, and with this change multiple of those in a struct
nlmsghdr, and at each level the len identifies there being multiple of
the next.

This patchset add resource-managed functions to automatically control the memory

extcon device driver on existing MAX14577 device because existed a little
difference between MAX77836 and MAX14577. Finally, Fix minor issue of extcon
driver.
Detailed description for patchset:
1. Add resource-managed functions
- Add resource-managed functions to automatically free the memory of extcon
structure and to control unregistration behavior as following. This new devm_*
functions applied all of extcon drivers in drivers/extcon/.

: devm_extcon_dev_allocate/free()
: extcon_dev_allocate/free() for devm_extcon_dev_allocate/free()
2. Add new MAX77836 extcon device
- Support MAX77836 device on existing MAX14577 device driver using
different compatible string. This patchset has dependency on MFD/
Regulator/Extcon. So, Lee Jones(MFD Maintainer) created Immutable
branch between MFD and Extcon due for v3.16 merge-window and then
I merged this patchset from MFD git repo[1] to Extcon git repo.

: Fix issue of extcon device name for probe
- extcon-max14577
: Fix probe failure about handling wrong return value.
: Properly Handle return value of regmap_irq_get_virq function.

We setting client connection state before start of full connect procedure so
in both cased the client state will be MEI_FILE_CONNECTING

The interlock is resolved by moving client to connecting state

The asm-generic, big-endian version of zero_bytemask creates a mask of
bytes preceding the first zero-byte by left shifting ~0ul based on the
position of the first zero byte.
Unfortunately, if the first (top) byte is zero, the output of
prep_zero_mask has only the top bit set, resulting in undefined C
behaviour as we shift left by an amount equal to the width of the type.
As it happens, GCC doesn't manage to spot this through the call to fls(),
but the issue remains if architectures choose to implement their shift
instructions differently.
An example would be arch/arm/ (AArch32), where LSL Rd, Rn, #32 results
in Rd == 0x0, whilst on arch/arm64 (AArch64) LSL Xd, Xn, #64 results in
Xd == Xn.
Rather than check explicitly for the problematic shift, this patch adds
an extra shift by 1, replacing fls with __fls. Since zero_bytemask is
never called with a zero argument (has_zero() is used to check the data
first), we don't need to worry about calling __fls(0), which is
undefined.

This merges the patch to fix possible loss of dirty bit on munmap() or
madvice(DONTNEED). If there are concurrent writers on other CPU's that
have the unmapped/unneeded page in their TLBs, their writes to the page
could possibly get lost if a third CPU raced with the TLB flush and did
a page_mkclean() before the page was fully written.
Admittedly, if you unmap() or madvice(DONTNEED) an area _while_ another
thread is still busy writing to it, you deserve all the lost writes you
could get. But we kernel people hold ourselves to higher quality
standards than "crazy people deserve to lose", because, well, we've seen
people do all kinds of crazy things.

"A slighlty large fix for a subtle issue in the CPU hotplug code of

local timer and needs to set the interrupt affinity to itself.
Setting interrupt affinity to a not online cpu is prohibited and
therefor the timer interrupt ends up on the wrong cpu, which leads to
nasty complications.
The SoC folks tried to hack around that in the SoC code in some more
than nasty ways. The proper solution is to have a way to enforce the
affinity setting to a not online cpu. The core patch to the genirq
code provides that facility and the follow up patches make use of it
in the GIC interrupt controller and the exynos timer driver.
The change to the core code has no implications to existing users,
except for the rename of the locked function and therefor the
necessary fixup in mips/cavium. Aside of that, no runtime impact is
possible, as none of the existing interrupt chips implements anything
which depends on the force argument of the irq_set_affinity()
callback"

"Here are some kernfs fixes for 3.15-rc3 that resolve some reported
problems. Nothing huge, but all needed"
* tag 'driver-core-3.15-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core:
s390/ccwgroup: Fix memory corruption
kernfs: add back missing error check in kernfs_fop_mmap()
kernfs: fix a subdir count leak
Here are a number of USB fixes for 3.15-rc3. The majority are gadget
fixes, as we didn't get any of those in for 3.15-rc2. The others are
all over the place, and there's a number of new device id addtions as
well.

- Fix for broken ACPI notifications on some systems caused by
a recent ACPI hotplug commit that blocked the propagation of
unknown type notifications to device drivers inadvertently.

recently) work as intended which now is broken due to missing
braces. From Christoph Jaeger.

the Generic Serial Bus operation region access. From Lv Zheng.
