Pull tty/serial updates from Greg KH:
"Here's the big tty/serial driver update for 4.1-rc1.
It was delayed for a bit due to some questions surrounding some of the
console command line parsing changes that are in here. There's still
one tiny regression for people who were previously putting multiple
console command lines and expecting them all to be ignored for some
odd reason, but Peter is working on fixing that. If not, I'll send a
revert for the offending patch, but I have faith that Peter can
address it.
Other than the console work here, there's the usual serial driver
updates and changes, and a buch of 8250 reworks to try to make that
driver easier to maintain over time, and have it support more devices
in the future.
All of these have been in linux-next for a while"

Pull clock framework updates from Michael Turquette:
"The changes to the common clock framework for 4.0 are mostly new clock
drivers and updates to existing ones for feature enhancements and bug
fixes.
There is more churn than usual in the framework core due to the change
to introduce per-user unique struct clk pointers in 4.0. This caused
several regressions to surface, some of which were sent as fixes to
4.0. New generic clock drivers were added for GPIO- and PWM-based
clock controllers.
Additionally the common clk-divider code recieved several fixes to the
way it rounds rates"

Pull SCSI fixes from James Bottomley:
"I'd like to say these were a set of regressions for the recent merge
window code. Unfortunately, they all predate the merge window code
(stable cc'd).
There are two fixes for data integrity (mostly only showing up on
module removal), an mvsas crash with expander attached SATA devices
which goes back to the dawn of the driver but is only just being
picked up as sas expanders become a standard item in low end server
hardware, an am53c974 one because the interrupt data isn't fully
initialised before the line is and a megaraid_sas one because it uses
smp_processor_id() to select MSI-X queues and that now triggers a
WARN_ON()"

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull PMEM driver from Ingo Molnar:
"This is the initial support for the pmem block device driver:
persistent non-volatile memory space mapped into the system's physical
memory space as large physical memory regions.
The driver is based on Intel code, written by Ross Zwisler, with fixes
by Boaz Harrosh, integrated with x86 e820 memory resource management
and tidied up by Christoph Hellwig.
Note that there were two other separate pmem driver submissions to
lkml: but apparently all parties (Ross Zwisler, Boaz Harrosh) are
reasonably happy with this initial version.
This version enables minimal support that enables persistent memory
devices out in the wild to work as block devices, identified through a
magic (non-standard) e820 flag and auto-discovered if
CONFIG_X86_PMEM_LEGACY=y, or added explicitly through manipulating the
memory maps via the "memmap=..." boot option with the new, special '!'
modifier character.
Limitations: this is a regular block device, and since the pmem areas
are not struct page backed, they are invisible to the rest of the
system (other than the block IO device), so direct IO to/from pmem
areas, direct mmap() or XIP is not possible yet. The page cache will
also shadow and double buffer pmem contents, etc.
Initial support is for x86"

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.1 development cycle:
- A new GPIO hogging mechanism has been added. This can be used on
boards that want to drive some GPIO line high, low, or set it as
input on boot and then never touch it again. For some embedded
systems this is bliss and simplifies things to a great extent.
- Some API cleanup and closure: gpiod_get_array() and
gpiod_put_array() has been added to get and put GPIOs in bulk as
was possible with the non-descriptor API.
- Encapsulate cross-calls to the pin control subsystem in
<linux/gpio/driver.h>. Now this should be the only header any GPIO
driver needs to include or something is wrong. Cleanups
restricting drivers to this include are welcomed if tested.
- Sort the GPIO Kconfig and split it into submenus, as it was
becoming and unstructured, illogical and unnavigatable mess. I
hope this is easier to follow. Menus that require a certain
subsystem like I2C can now be hidden nicely for example, still
working on others.
- New drivers:
- New driver for the Altera Soft GPIO.
- The F7188x driver now handles the F71869 and F71869A variants.
- The MIPS Loongson driver has been moved to drivers/gpio for
consolidation and cleanup.
- Cleanups:
- The MAX732x is converted to use the GPIOLIB_IRQCHIP
infrastructure.
- The PCF857x is converted to use the GPIOLIB_IRQCHIP
infrastructure.
- Radical cleanup of the OMAP driver.
- Misc:
- Enable the DWAPB GPIO for all architectures. This is a "hard
IP" block from Synopsys which has started to turn up in so
diverse architectures as X86 Quark, ARC and a slew of ARM
systems. So even though it's not an expander, it's generic
enough to be available for all.
- We add a mock GPIO on Crystalcove PMIC after a long discussion
with Daniel Vetter et al, tracing back to the shootout at the
kernel summit where DRM drivers and sub-componentization was
discussed. In this case a mock GPIO is assumed to be the best
compromise gaining some reuse of infrastructure without making
DRM drivers overly complex at the same time. Let's see"

Currently, iflink of the parent interface was always accessed, even
when interface didn't have a parent and hence we crashed there.
Handle the interface types properly: for a child interface, return
the ifindex of the parent, for parent interface, return its ifindex.
For child devices, make sure to set the parent pointer prior to
invoking register_netdevice(), this allows the new ndo to be called
by the stack immediately after the child device is registered.

Function get_rx_status is reading from the response-fifo.

Pull ACPICA updates from Rafael Wysocki:
"This updates the kernel's ACPICA code to upstream revision 20150410
and adds a fix for a GPE handling regression introduced during the
3.19 cycle on top of that.
Included are two stable-candidate bug fixes (one of them fixing a 3.16
regression), multiple other fixes and a bunch of cleanups.
Specifics:
- Fix for a GPE handling regression on Dell Latitude D600 that caused
GPE signaling to stop working on that machine, which appears to be
due to a hardware glitch, but it used to work and it can be made
work again in a relativly straightforward way (Rafael J Wysocki).
- Fix for a mutex unlock regression related to the handling of ACPI
tables introduced during the 3.16 development cycle (Octavian
Purdila).
- _REV modification to always return 2 which has been done by all
versions of Windows since NT and the firmware people started to use
it to distinguish between OSes in their AML and do some silly and
wrong things on that basis (Bob Moore).
- Fixes and cleanups related to the acpi_physicall_address data type
including one stable-candidate fix for an issue occasionally
occuring on 64-bit machines running 32-bit kernels where using
offsets provided by the firmware may lead to address overflows (Lv
Zheng).
- External() opcode support infrastructure needed for recompiling
disassembled ACPI tables in some cases including interpreter
modification to ignore that opcode (Bob Moore).
- Support for the "Windows 2015" string in _OSI (Bob Moore).
- GPE debug interface change to return values read from hardware
registers (Lv Zheng).
- Removal of the __DATE__ macro usage in tools (Rasmus Villemoes).
- Assorted minor fixes and cleanups (Lv Zheng, Rickard Strandqvist,
Bob Moore)"

In commit 04ffcb255f22 ("net: Add ndo_gso_check") Tom originally
added the 'dev' argument to be able to call ndo_gso_check().
Then later, when generalizing this in commit 5f35227ea34b
("net: Generalize ndo_gso_check to ndo_features_check")
Jesse removed the call to ndo_gso_check() in netif_needs_gso()
by calling the new ndo_features_check() in a different place.
This made the 'dev' argument unused.
Remove the unused argument and go back to the code as before.

When you redirect a VLAN device to any device, you end up with
crap in af_packet on the xmit path because hard_header_len is
not equal to skb->mac_len. So the redirected packet contains
four extra bytes at the start which then gets interpreted as
part of the MAC address.
This patch fixes this by only pushing skb->mac_len. We also
need to fix ifb because it tries to undo the pushing done by
act_mirred.

mvsas is giving a General protection fault when it encounters an expander
attached ATA device. Analysis of mvs_task_prep_ata() shows that the driver is
assuming all ATA devices are locally attached and obtaining the phy mask by
indexing the local phy table (in the HBA structure) with the phy id. Since
expanders have many more phys than the HBA, this is causing the index into the
HBA phy table to overflow and returning rubbish as the pointer.
mvs_task_prep_ssp() instead does the phy mask using the port properties.
Mirror this in mvs_task_prep_ata() to fix the panic.

The RTC driver supports two flavors of S5M devices: S5M8767-like and
S2MPS14-like.
On S2MPS13 and S2MPS14 devices the RTC module is the same so we want to
re-use the existing support of S2MPS14. However device type was passed
from parent MFD driver in platform data structure. This way for the
S2MPS13 device the main MFD driver passed device type of 'S2MPS13X'.
Instead decouple detecting of device type between main MFD and RTC driver.
This allows adding support for other S2MPS14 variations (like S2MPS11 and
S2MPS13) easily by adding to mfd/sec-core.c:
static const struct mfd_cell s2mps13_devs[] = {
{ .name = "s2mps14-rtc", }
};

sync_buffer() needs the mmap_sem for two distinct operations, both only
occurring upon user context switch handling:
1) Dealing with the exe_file.
2) Adding the dcookie data as we need to lookup the vma that
backs it. This is done via add_sample() and add_data().
This patch isolates 1), for it will no longer need the mmap_sem for
serialization. However, for now, make of the more standard
get_mm_exe_file(), requiring only holding the mmap_sem to read the value,
and relying on reference counting to make sure that the exe file won't
dissappear underneath us while doing the get dcookie.
As a consequence, for 2) we move the mmap_sem locking into where we really
need it, in lookup_dcookie(). The benefits are twofold: reduce mmap_sem
hold times, and cleaner code.

The hym8563 datasheet describes the clock output control-bit as "when set
to logic 0, the square wave output is enable, when set to logic 1, the
CLKOUT output is inhibited". But in reality the setting is exactly
opposite.
Before now, the clock output was not really used, but on the rk3288 soc
this generated clock is used to supply the temperature sensor block and
the swapped bit value prevented it from working. With the corrected
value, the tsadc now reports correct values.

register writes
RTC module contains a kicker mechanism to prevent any spurious writes from
changing the register values. This mechanism requires two MMR writes to
the KICK0 and KICK1 registers with exact data values before the kicker
lock mechanism is released.
Currently the driver release the lock in the probe and leaves it enabled
until the rtc driver removal. This eliminates the idea of preventing
spurious writes when RTC driver is loaded. So implement rtc lock and
unlock functions before and after register writes.
This is as advised by Paul to implement lock and unlock functions in the
driver and not to unlock and leave it in probe. The same discussion can
be seen here:

__rtc_read_time logs should be debug logs instead of error logs.
For example, when the RTC clock is not set, it's not really useful
to print a kernel error log every time someone tries to read the clock:
~ # hwclock -r
[ 604.508263] rtc rtc0: read_time: fail to read
hwclock: RTC_RD_TIME: Invalid argument
If there's a real error, it's likely that lower level or higher level
code will tell it anyway. Make these logs debug logs, and also print
the error code for the read failure.
