Add support driver for Intel Rapid Start Technology
Intel Rapid Start Technology is a firmware-based suspend-to-disk implementation. Once placed in S3, the device will wake once either a timeout elapses or the battery reaches a critical level. It will then resume to the firmware and copy the contents of RAM to a specialised partition, and then power off the machine. If the user turns the machine back on the firmware will copy the contents of the partition back to RAM and then resume from S3 as normal. This driver provides an interface for configuring the wakeup events and timeout. It still requires firmware support and an appropriate suspend partition.

perf tools: fix a typo of a Power7 event name
In the Power7 PMU guide: https://www.power.org/documentation/commonly-used-metrics-for-performance-analysis/ PM_BRU_MPRED is referred to as PM_BR_MPRED. It fixed the typo by changing the name of the event in kernel and documentation accordingly. This patch changes the ABI, there are some reasons I think it's ok: - It is relatively new interface, specific to the Power7 platform. - No tools that we know of actually use this interface at this point (none are listed near the interface). - Users of this interface (eg oprofile users migrating to perf) would be more used to the "PM_BR_MPRED" rather than "PM_BRU_MPRED". - These are in the ABI/testing at this point rather than ABI/stable, so hoping we have some wiggle room.

Several InfiniBand HCAs allow configuring the completion vector per CQ.

In other words, configuring the completion vector properly not only allows reducing latency on an initiator connected to multiple SRP targets but also allows improving throughput.

MUSB was taught that it needs to be built for host-only and
device-only modes too. We had this support long ago but it
involved a ridiculous amount of ifdefs. Now we have a much
cleaner approach.
Samsung Exynos4 platform now implements HSIC support.
We're introducing support for AB8540 and AB9540 PHYs.
MUSB module reinsertion now works as expected, before we were
getting -EBUSY being returned by the resource checks done on
driver core.
DWC3 now has minimum support for TI's AM437x series of SoCs.
OMAP5 USB3 PHY learned one extra DPLL configuration values because
that PHY is reused in TI's DRA7xx devices.
We're introducing support for Faraday fotg210 UDCs.
Last, but not least, the usual set of non-critical fixes and cleanups
ranging from usage of platform_{get,set}_drvdata to lock improvements.

HID: wiimote: add "bboard_calib" attribute
Balance-Boards provide 3 16bit calibration values for each of the 4 sensors. We provide these now as 192bit value via a new "bboard_calib" sysfs attribute. We also re-read the calibration data from the device whenever user-space attempts to read this file. On normal Nintendo boards, this always produces the same results, however, on some 3rd party devices these values change until the device is fully initialized. As I have currently no idea how long to wait until it's ready (sometimes takes up to 10s?) we provide a simple workaround for users by reading this file. If we, at some point, figure out how it works, we can implement it in the kernel and provide offline data via "bboard_calib". This won't break user-space then.

Two new attributes, "extension" and "devtype" now allow user-space to read the extension type and device type. As device detection is asynchronous, we send a CHANGED event after it is done. This also allows user-space to wait for a device to settle before opening its input event devices. The "extension" device is compatible with the old "extension" sysfs field (which was registered by the static extension support code).

perf: Expand definition of sysfs format attribute
Make it explicit that the format attributes may define overlapping bit ranges. Unfortunately this was left unspecified originally, and all the examples show non-overlapping ranges. I don't believe this is an ABI change, as we are defining something that was previously undefined, but others may disagree. The POWER8 PMU would like to define overlapping ranges, as bit ranges in the event code have different meanings for certain events. It will also allow us to define an overarching "event" field, that encompasses all others. As far as I can see perf is comfortable with this change, however I am not sure if there are any other users of the interface.

ACPI / hotplug: Use device offline/online for graceful hot-removal
Modify the generic ACPI hotplug code to be able to check if devices scheduled for hot-removal may be gracefully removed from the system using the device offline/online mechanism introduced previously. Namely, make acpi_scan_hot_remove() handling device hot-removal call device_offline() for all physical companions of the ACPI device nodes involved in the operation and check the results. If any of the device_offline() calls fails, the function will not progress to the removal phase (which cannot be aborted), unless its (new) force argument is set (in case of a failing offline it will put the devices offlined by it back online). In support of 'forced' device hot-removal, add a new sysfs attribute 'force_remove' that will reside under /sys/firmware/acpi/hotplug/. Signed-off-by: Rafael J.

Driver core: Add offline/online device operations
In some cases, graceful hot-removal of devices is not possible, although in principle the devices in question support hotplug. For example, that may happen for the last CPU in the system or for memory modules holding kernel memory. In those cases it is nice to be able to check if the given device can be gracefully hot-removed before triggering a removal procedure that cannot be aborted or reversed. Unfortunately, however, the kernel currently doesn't provide any support for that. To address that deficiency, introduce support for offline and online operations that can be performed on devices, respectively, before a hot-removal and in case when it is necessary (or convenient) to put a device back online after a successful offline (that has not been followed by removal). The idea is that the offline will fail whenever the given device cannot be gracefully removed from the system and it will not be allowed to use the device after a successful offline (until a subsequent online) in analogy with the existing CPU offline/online mechanism. For now, the offline and online operations are introduced at the bus type level, as that should be sufficient for the most urgent use cases (CPUs and memory modules). In the future, however, the approach may be extended to cover some more complicated device offline/online scenarios involving device drivers etc. The lock_device_hotplug() and unlock_device_hotplug() functions are introduced because subsequent patches need to put larger pieces of code under device_hotplug_lock to prevent race conditions between device offline and removal from happening.

rbd: don't create sysfs entries for non-mapped snapshots
When an rbd image gets mapped a device entry gets created for it
under /sys/bus/rbd/devices/<id>/. Inside that directory there are
sysfs files that contain information about the image: its size,
feature bits, major device number, and so on.
Additionally, if that image has any snapshots, a device entry gets
created for each of those as a "child" of the mapped device. Each
of these is a subdirectory of the mapped device, and each directory
contains a few files with information about the snapshot (its
snapshot id, size, and feature mask).
There is no clear benefit to having those device entries for the
snapshots. The information provided via sysfs of of little real
value--and all of it is available via rbd CLI commands. If we
still wanted to see the kernel's view of this information it could
be done much more simply by including it in a single sysfs file for
the mapped image.
But there *is* a clear cost to supporting them. Every time a snapshot
context changes, these entries need to be updated (deleted snapshots
removed, new snapshots created). The rbd driver is notified of
changes to the snapshot context via callbacks from an osd, and care
must be taken to coordinate removal of snapshot data structures
with the possibility of one these notifications occurring.
Things would be considerably simpler if we just didn't have to
maintain device entries for the snapshots.
So get rid of them.
The ability to map a snapshot of an rbd image will remain; the only
thing lost will be the ability to query these sysfs directories for
information about snapshots of mapped images.
This resolves:
