Here's the big staging driver patchset for 4.1-rc1.
There's a lot of patches here, the Outreachy application period happened
during this development cycle, so that means that there was a lot of
cleanup patches accepted. Other than the normal coding style and sparse
fixes here, there are some driver updates and work toward making some of
the drivers into "mergable" shape (like the Unisys drivers.)
All of these have been in linux-next for a while.

Here's the driver-core / kobject / lz4 tree update for 4.1-rc1.
Everything here has been in linux-next for a while with no reported

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.

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"

resume timeout value.

- Revert a 3.17 hibernate commit that was supposed to fix an issue
related to e820 reserved regions, but broke resume from hibernation
on Lenovo x230 (Rafael J Wysocki).
- Prevent the ACPI cpuidle driver from overwriting the name and
description of the C0 state set by the core when the list of
C-states changes (Thomas Schlichter).
- Remove the no longer needed state_count field from struct cpuidle_device
which prevents the list of C-states shown by the sysfs interface from
becoming incorrect when the current number of them is different from
the number of C-states on boot (Bartlomiej Zolnierkiewicz).
- The cpufreq core updates the policy object of the only online CPU
during system resume to make it reflect the current hardware state,
but it always assumes that CPU to be CPU0 which need not be the
case, so fix the code to avoid that assumption (Viresh Kumar).

Communications with a hardware vendor confirm that the expected behaviour
on systems that set the FADT ASPM disable bit but which still grant full
PCIe control is for the OS to leave any BIOS configuration intact and
refuse to touch the ASPM bits. This mimics the behaviour of Windows.

The dw_mmc driver changes to make the IO accesors endian agnostic did not
take into account the fifo accesses do not need to be swapped. To fix this
add a mmci_fifo_read/write wrapper to allow these to be passed through the
IO without being swapped.
Since these are now specific functions, it would be easier just to store
the pointer to the fifo registers in the host block instead of the offset
to them. So change the host->data_offset to host->fifo_reg (which also
means we catch all the places this is read or written).

Merge tag 'irqchip-core-4.0' of git://git.infradead.org/users/jcooper/linux into irq/core
irqchip core changes for v4.0 from Jason Cooper
- ST
- New driver, irq-st
- Renesas
- Use u32 type for 32bit regs
There is a number of cases where a kernel subsystem may want to
introspect the state of an interrupt at the irqchip level:
- When a peripheral is shared between virtual machines,
its interrupt state becomes part of the guest's state,
and must be switched accordingly. KVM on arm/arm64 requires
this for its guest-visible timer
- Some GPIO controllers seem to require peeking into the
interrupt controller they are connected to to report
their internal state
This seem to be a pattern that is common enough for the core code
to try and support this without too many horrible hacks. Introduce
a pair of accessors (irq_get_irqchip_state/irq_set_irqchip_state)
to retrieve the bits that can be of interest to another subsystem:
pending, active, and masked.
- irq_get_irqchip_state returns the state of the interrupt according
to a parameter set to IRQCHIP_STATE_PENDING, IRQCHIP_STATE_ACTIVE,
IRQCHIP_STATE_MASKED or IRQCHIP_STATE_LINE_LEVEL.
- irq_set_irqchip_state similarly sets the state of the interrupt.

The PCI "ACPI additions for FW latency optimizations" ECN (link below)
defines two functions in the PCI _DSM:
Function 8, "Reset Delay," applies to the entire hierarchy below a PCI
host bridge. If it returns one, the OS may assume that all devices in
the hierarchy have already completed power-on reset delays.
Function 9, "Device Readiness Durations," applies only to the object
where it is located. It returns delay durations required after various
events if the device requires less time than the spec requires. Delays
from this function take precedence over the Reset Delay function.
Add support for Reset Delay and part of Device Readiness Durations.

The PCI Firmware Specification, r3.0, sec 4.6.4.1.3, defines a single UUID
for an ACPI _DSM method to provide device-specific control functions. This
_DSM method support several functions, including PCI Express Slot
Information, PCI Express Slot Number, PCI Bus Capabilities, etc.
Move the UUID definition from pci/pci-label.c, where it could be used only
for one function, to pci/pci-acpi.c where it can be shared for all these
functions.

SCSI transport drivers and SCSI LLDs block a SCSI device if the
transport layer is not operational. This means that in this state
no requests should be processed, even if the REQ_PREEMPT flag has
