Pull regulator updates from Mark Brown:
"Another release, another set of regulator updates. Not much of it is
showing up in the code yet but there's been a lot of discussion going
on about how to enhance the regulator API to work better with modern
SoCs which have a microcontroller sitting between Linux and the
hardware.
I'm hopeful that'll start to come through into mainline for v4.2 but
it's not quite there for v4.1 - what we do have (along with the usual
small updates is) is:
- work from Bjorn Andersson on refactoring the configuration of
regulator loading interfaces to be useful for use with
microcontrollers, the existing interfaces were never actually
useful for anything as-is since nobody was willing to put enough
data into public code.
- a summary tree display in debugfs from Heiko Stübner.
- support for act6000 regulators"

The act88600/act8846/act8865 regulators have a number of input supplies
supplying the individual regulators. This may even be recursively like on
most Rockchip boards using the act8846 where REG4 is most of the time
connected to the inl1-supply.
Therefore add the ability to specify the input supplies for the individual inputs.
The input-names are taken from the datasheets of act8600, act8846 and act8865.
On the act8600 some regulators do not have separate input supplies.

Pull spi updates from Mark Brown:
"Only one framework update this time around, a change from Lars-Peter
to move full to pm_ops and remove the legacy bus PM ops. Otherwise
it's all driver updates:
- make the spidev driver complain loudly if registered as spidev with
DT rather than with a compatible string, hopefully helping people
avoid making that mistake.
- error handling and robustness fixes for the Designware and Intel
MID drivers from Andy Shevchenko.
- substantial performance improvements for the Raspberry Pi driver
from Martin Sperl.
- several new features for spidev_test from Adrian Remonda and Ian
Abbott"

We have found that we can sometimes see read failures on boards with
high-capacitance SPI lines. It seems that the controller samples the Rx
data line too early, and its register interface has an "Rx Sample Delay"
setting to fine-tune against this issue.
This patch adds a new optional device tree entry that can configure this
delay in terms of nanoseconds. The kernel will calculate the
best-fitting amount of parent clock ticks to program the controller with
based on that.

This patch adds DMA capabilities to the spi-qup driver. If DMA channels are
present, the QUP will use DMA instead of block mode for transfers to/from SPI
peripherals for transactions larger than the length of a block.

The fsl-imx-cspi binding contains language indicating compatible
strings to be used that is not valid for all supported parts
e.g. Should be "fsl,<soc>-cspi" or "fsl,<soc>-ecspi". Fix this
by enumerating the set of valid compatible strings.
The binding is also missing the clocks/clock-names properties
so document these and the two required ipg and per clocks.

When the CONTINUE bit is set, the interrupt status we are polling to
identify if a transaction has finished can be sporadic. Even though
the transfer has finished, the interrupt status may erroneously
indicate that there is still data in the FIFO. This behaviour causes
random timeouts in large PIO transfers.
Instead of using the CONTINUE bit to control the CS lines, use the SPI
core's CS GPIO handling. Also, now that the CONTINUE bit is not being
used, we can poll for the ALLDONE interrupt to indicate transfer
completion.

This patch updates the binding information to reflect the
extra dt options which are now supported by the sdhci-st.c
driver which enable support for stih407 family silicon.
STiH410 SoC and later support UHS modes for eMMC, so the
driver now makes use of these common bindings. Examples
are provided for both eMMC (which has additional bindings)
and also sd slot for STiH407.

The eMMC on a tablet I've will stop working / communicating as soon as
the kernel executes:
mmc_switch(card, EXT_CSD_CMD_SET_NORMAL,
EXT_CSD_HPI_MGMT, 1,
card->ext_csd.generic_cmd6_time);
There seems to be no way to reliable identify eMMC-s which have a broken
hpi implementation, but at least for eMMC's which are soldered onto a board
we can work around this by specifying that hpi is broken in devicetree.

On some boards, such as the LaCie 2Big Network v2 or 2Big NAS (based on
Marvell Kirkwood SoCs), an I2C fan controller is used but the alarm
signal is wired to a separate GPIO. Unfortunately, the gpio-fan driver
can't be used to handle GPIO alarm alone from DT: an error is returned
if the "gpios" DT property is missing.
This patch allows to use the gpio-fan driver even if the "alarm-gpios"
DT property is defined alone.

TS3000GB0 has a new device ID (0x2913). Since IDT's datasheets suggest
that the upper 8 bit of the device ID reflect the chip ID and the lower
8 bit reflect the version number, modify the code to accept all chips
with ID 0x29xx.
Also add support for TS3001 and TSE2004.
Some of the datasheets for older chips are no longer available from
the IDT web site, so replace explicit links in the documentation with
a generic note.

IT8781F is mostly compatible to IT8782F. Major difference is that it only
supports four instead of six UART channels, and therefore does not share
the uart6 pins.

Pull x86 asm changes from Ingo Molnar:
"There were lots of changes in this development cycle:
- over 100 separate cleanups, restructuring changes, speedups and
fixes in the x86 system call, irq, trap and other entry code, part
of a heroic effort to deobfuscate a decade old spaghetti asm code
and its C code dependencies (Denys Vlasenko, Andy Lutomirski)
- alternatives code fixes and enhancements (Borislav Petkov)
- simplifications and cleanups to the compat code (Brian Gerst)
- signal handling fixes and new x86 testcases (Andy Lutomirski)
- various other fixes and cleanups
By their nature many of these changes are risky - we tried to test
them well on many different x86 systems (there are no known
regressions), and they are split up finely to help bisection - but
there's still a fair bit of residual risk left so caveat emptor"

Commit:
e2b32e678513 ("x86, kaslr: randomize module base load address")
made module base address randomization unconditional and didn't regard
disabled KKASLR due to CONFIG_HIBERNATION and command line option
"nokaslr". For more info see (now reverted) commit:
f47233c2d34f ("x86/mm/ASLR: Propagate base load address calculation")
In order to propagate KASLR status to kernel proper, we need a single bit
in boot_params.hdr.loadflags and we've chosen bit 1 thus leaving the
top-down allocated bits for bits supposed to be used by the bootloader.

Pull EFI updates from Matt Fleming:
- Fixes and cleanups for SMBIOS 3.0 DMI code. (Ivan Khoronzhuk)
- A new efi=debug command line option that enables debug output in the
EFI boot stub and results in less verbose EFI memory map output by
default. (Borislav Petkov)
- Disable interrupts around EFI calls and use a more standard page
table saving and restoring idiom when making EFI calls. (Ingo Molnar)
- Reduce the number of memory allocations performed when allocating the
FDT in EFI boot stub by retrieving size from the FDT header in the
EFI config table. (Ard Biesheuvel)

This patch adds support to migrate vcpu interrupts. Two new vcpu ioctls
are added which get/set the complete status of pending interrupts in one
go. The ioctls are marked as available with the new capability
KVM_CAP_S390_IRQ_STATE.
We can not use a ONEREG, as the number of pending local interrupts is not
constant and depends on the number of CPUs.
To retrieve the interrupt state we add an ioctl KVM_S390_GET_IRQ_STATE.
Its input parameter is a pointer to a struct kvm_s390_irq_state which
has a buffer and length. For all currently pending interrupts, we copy
a struct kvm_s390_irq into the buffer and pass it to userspace.
To store interrupt state into a buffer provided by userspace, we add an
ioctl KVM_S390_SET_IRQ_STATE. It passes a struct kvm_s390_irq_state into
the kernel and injects all interrupts contained in the buffer.

This fixes a bug introduced with commit c05c4186bbe4 ("KVM: s390:
add floating irq controller").
get_all_floating_irqs() does copy_to_user() while holding
a spin lock. Let's fix this by filling a temporary buffer
first and copy it to userspace after giving up the lock.
