TTY/Serial patches for 4.9-rc1
Here is the big TTY and Serial patch set for 4.9-rc1. It also includes some drivers/dma/ changes, as those were needed by some serial drivers, and they were all acked by the DMA maintainer. Also in here is the long-suffering ACPI SPCR patchset, which was passed around from maintainer to maintainer like a hot-potato. Seems I was the sucker^Wlucky one. All of those patches have been acked by the various subsystem maintainers as well. All of this has been in linux-next with no reported issues.

Merge branch 'smp-hotplug-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull CPU hotplug updates from Thomas Gleixner:
"Yet another batch of cpu hotplug core updates and conversions:
- Provide core infrastructure for multi instance drivers so the
drivers do not have to keep custom lists.
- Convert custom lists to the new infrastructure. The block-mq custom
list conversion comes through the block tree and makes the diffstat
tip over to more lines removed than added.
- Handle unbalanced hotplug enable/disable calls more gracefully.
- Remove the obsolete CPU_STARTING/DYING notifier support.
- Convert another batch of notifier users.
The relayfs changes which conflicted with the conversion have been
shipped to me by Andrew.
The remaining lot is targeted for 4.10 so that we finally can remove
the rest of the notifiers"

Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq updates from Thomas Gleixner:
"The irq departement proudly presents:
- A rework of the core infrastructure to optimally spread interrupt
for multiqueue devices. The first version was a bit naive and
failed to take thread siblings and other details into account.
Developed in cooperation with Christoph and Keith.
- Proper delegation of softirqs to ksoftirqd, so if ksoftirqd is
active then no further softirq processsing on interrupt return
happens. Otherwise we try to delegate and still run another batch
of network packets in the irq return path, which then tries to
delegate to ksoftirqd .....
- A proper machine parseable sysfs based alternative for
/proc/interrupts.
- ACPI support for the GICV3-ITS and ARM interrupt remapping
- Two new irq chips from the ARM SoC zoo: STM32-EXTI and MVEBU-PIC
- A new irq chip for the JCore (SuperH)
- The usual pile of small fixlets in core and irqchip drivers"

thread stack caching performance optimization. (Andy Lutomirski)

- A large number of dumpstack infrastructure enhancements and an
unwinder abstraction. The secret long term plan is safe(r) live

ACPI material for v4.9-rc1
- Update of the ACPICA code in the kernel to upstream revision 20160831 with
the following major changes:
* New mechanism for GPE masking.
* Fixes for issues related to the LoadTable operator and table loading.
* Fixes for issues related to so-called module-level code (MLC), that is
AML that doesn't belong to any methods.

- ACPI sysfs interface updates to fix GPE handling (on top of the new GPE
masking mechanism in ACPICA) and issues related to table loading (Lv Zheng).
- New watchdog driver based on the ACPI WDAT (ACPI Watchdog Action Table),
needed on some platforms to replace the iTCO watchdog that doesn't work there
and related updates of the intel_pmc_ipc, i2c/i801 and MFD/lcp_ich drivers
(Mika Westerberg).
- Driver core fix to prevent it from leaking secondary fwnode objects during
device removal (Lukas Wunner).
- New definitions of built-in properties for UART in ACPI-based x86 SoC drivers
and a 8250_dw driver quirk for the APM X-Gene SoC (Heikki Krogerus).
- New device ID for the Vulcan SPI controller and constification of local
strucures in the AMD SoC (APD) ACPI driver (Kamlakant Patel, Julia Lawall).
- Fix for a bug causing the allocation of PCI resorces to fail if
ACPI-enumerated child platform devices are registered below the PCI
devices in question (Mika Westerberg).
- Change of the default polarity for PCI legacy IRQs to high on systems
booting wth ACPI on platforms with a GIC interrupt controller model
fixing the discrepancy between the specification and HW behavior (Lorenzo
Pieralisi).
- Fixes for the handling of system suspend/resume in the ACPI EC driver and
update of that driver to make it cope with the cases when the EC device
defined in the ECDT has to be used throughout the entire system life cycle
(Lv Zheng).
- Update of the ACPI CPPC library to allow it to batch requests sent over the
PCC channel (to reduce overhead), to support the fixed functional hardware
(FFH) CPPC registers access type, to notify the mailbox framework about TX
completions when the interrupt flag is set for the PCC mailbox, and to
support HW-Reduced Communication Subspace type 2 (Ashwin Chaugule, Prashanth
Prakash, Srinivas Pandruvada, Hoan Tran).
- ACPI button driver fix and documentation update related to the handling of
laptop lids (Lv Zheng).
- ACPI battery driver initialization fix (Carlos Garnacho).
- ACPI GPIO enumeration documentation update (Mika Westerberg).

Merge tag 'acpi-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki:
"First off, the ACPICA code in the kernel is updated to upstream
revision 20160831 that brings in a few bug fixes and cleanups. In
particular, it is possible to mask GPEs now (and the sysfs interface
for GPE control is fixed on top of that), problems related to the
table loading mechanism are fixed and all code related to FADT version
2 (which has never been part of the ACPI specification) is dropped.
On the new features front, there is a new watchdog driver based on the
ACPI WDAT (ACPI Watchdog Action Table), needed on some platforms to
replace the iTCO watchdog that doesn't work there, and some UART
devices get new definitions of built-in properties (to be accessed via
the generic device properties API).
Also, included is a fix for an ACPI-related PCI resorces allocation
issue and a few problems in the EC driver and in the button and
battery drivers are fixed.
In addition to that, the ACPI CPPC library is updated to make batching
of requests sent over the PCC channel possible (which reduces the PCC
usage overhead substantially in some cases) and to support functional
fixed hardware (FFH) type of CPPC registers access (which will allow
CPPC to be used on x86 too in the future).
As usual, there are some assorted fixes and cleanups too.
Specifics:
- Update of the ACPICA code in the kernel to upstream revision
20160831 with the following major changes:
* New mechanism for GPE masking.
* Fixes for issues related to the LoadTable operator and table
loading.
* Fixes for issues related to so-called module-level code (MLC),

Power management material for v4.9-rc1
- Add a mechanism for passing hints from the scheduler to cpufreq governors

Pull power management updates from Rafael Wysocki:
"Traditionally, cpufreq is the area with the greatest number of
changes, but there are fewer of them than last time. There also is
some activity in the generic power domains and the devfreq frameworks,
a couple of system suspend and hibernation fixes and some assorted
changes in other places.
One new feature is the cpufreq change to allow the scheduler to pass
hints to the governors' utilization update callbacks and some code
rework based on that. Another one is the support for domain removal in
the generic power domains framework. Also it is now possible to use
hibernation with PAGE_POISONING_ZERO enabled and devfreq supports the
RockChip DFI controller and the rk3399 DMC.
The rest of the changes is mostly fixes and cleanups in a number of
places.
Specifics:
- Add a mechanism for passing hints from the scheduler to cpufreq
governors via their utilization update callbacks and use it to
introduce "IOwait boosting" into the schedutil governor and
intel_pstate that will make them boost performance if the enqueued

This leads to accesses to VPEs in secondary cores being performed incorrectly since mips_cm_vp_id calculates the wrong ID to write to the local "other" registers. Fix this by examining the number of VPEs in the core as reported by the CM. This patch presumes that the number of VPEs will be the same in each core of the system. As this path only applies to systems with CM version 2.5 or lower, and this property is true of all such known systems, this is likely to be fine but is described in a comment for good measure.

SCSI fixes on 20161001
One final fix before 4.8: there's a memory leak triggered by turning scsi mq off due to the fact that we assume on host release that the already running hosts weren't mq based because that's the state of the global flag (even though they were), so fix it by tracking this on a per host host basis.
