git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid
Pull HID updates from Jiri Kosina:
1) Patchset from Henrik Rydberg which substantially reduces irqsoff
latency for all input devices. In addition to that, Henrik reworked
multitouch handling in order to reduce runtime memory consumption.
This patchset touches code in Input subsystem as well. All the
changes have been Acked by Dmitry, and we agreed to do it this way
due to inter-dependencies between the patchset and subsequent
changes in HID subsystem.
2) Rework, clenaups and a lot of fixes to picolcd driver by Bruno
Prémont.
3) Core report descriptor handling fix which fixes resume issue on some
devices, by Kevin Daughtridge

Many regulators support a bypass mode where they simply switch their
input supply to the output. This is mainly used in low power retention
states where power consumption is extremely low so higher voltage or
less clean supplies can be used.
Support this by providing ops for the drivers and a consumer API which
allows the device to be put into bypass mode if all consumers enable it
and the machine enables permission for this.
This is not supported as a mode since the existing modes are rarely used
due to fuzzy definition and mostly redundant with modern hardware which is
able to respond promptly to load changes.

According to the ASUS WMI spec., to enable resume on lid open should
use the device ID(0x00120032), but it doesn't work indeed.
After discussing with ASUS' BIOS engineer, they say wake on lid open
doesn't have a uniq device ID(0x00120032) in the BIOS. It shares the same
device ID with deep S3(0x00120031), and the deep S3(resume on lid open)
is disable by default.
Adding this option in asus wmi sysfs
/sys/devices/platform/<platform>/lid_resume
so that userspace apps can enable/disable this feature by themselves.

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel:
"The most important part of these updates is the IOMMU groups code
enhancement written by Alex Williamson. It abstracts the problem that
a given hardware IOMMU can't isolate any given device from any other
device (e.g. 32 bit PCI devices can't usually be isolated). Devices
that can't be isolated are grouped together. This code is required
for the upcoming VFIO framework.
Another IOMMU-API change written by me is the introduction of domain
attributes. This makes it easier to handle GART-like IOMMUs with the
IOMMU-API because now the start-address and the size of the domain
address space can be queried.
Besides that there are a few cleanups and fixes for the NVidia Tegra
IOMMU drivers and the reworked init-code for the AMD IOMMU. The
latter is from my patch-set to support interrupt remapping. The rest
of this patch-set requires x86 changes which are not mergabe yet. So
full support for interrupt remapping with AMD IOMMUs will come in a
future merge window."

"The list of changes worth pointing out explicitly:
- We are getting 'UHID', which is a new framework for implementing HID
transport drivers in userspace (this is different from HIDRAW, which
is transport-independent and provides report parsing facilities;
uhid is for the other (transport) part of the pipeline).
It's needed for (and currently being used by) Bluetooth-LowEnergy,
as its specification mandates things we don't want in the kernel.
Written by David Herrmann.
- there have been quite a few bugs in runtime suspend/resume paths
(probably never reported to actually happen in the wild, but still).

Pull Xen update from Konrad Rzeszutek Wilk:
"Features:
* Performance improvement to lower the amount of traps the hypervisor
has to do 32-bit guests. Mainly for setting PTE entries and
updating TLS descriptors.
* MCE polling driver to collect hypervisor MCE buffer and present
them to /dev/mcelog.
* Physical CPU online/offline support. When an privileged guest is
booted it is present with virtual CPUs, which might have an 1:1 to
physical CPUs but usually don't. This provides mechanism to
offline/online physical CPUs.
Bug-fixes for:
* Coverity found fixes in the console and ACPI processor driver.
* PVonHVM kexec fixes along with some cleanups.
* Pages that fall within E820 gaps and non-RAM regions (and had been
released to hypervisor) would be populated back, but potentially in
non-RAM regions."

This patch simply adds a newline character at end-of-file to those
files in Documentation/ that currently lack one.
This is done for a few different reasons:
A) It's rather annoying when you do "cat some_file.txt" that your
prompt/cursor ends up at the end of the last line of output rather
than on a new line.
B) Some tools that process files line-by-line may get confused by the
lack of a newline on the last line.
C) The "\ No newline at end of file" line in diffs annoys me for some
reason.
So, let's just add the missing newline once and for all.

IOMMU device groups are currently a rather vague associative notion
with assembly required by the user or user level driver provider to
do anything useful. This patch intends to grow the IOMMU group concept
into something a bit more consumable.
To do this, we first create an object representing the group, struct
iommu_group. This structure is allocated (iommu_group_alloc) and
filled (iommu_group_add_device) by the iommu driver. The iommu driver
is free to add devices to the group using it's own set of policies.
This allows inclusion of devices based on physical hardware or topology
limitations of the platform, as well as soft requirements, such as
multi-function trust levels or peer-to-peer protection of the
interconnects. Each device may only belong to a single iommu group,
which is linked from struct device.iommu_group. IOMMU groups are
maintained using kobject reference counting, allowing for automatic
removal of empty, unreferenced groups. It is the responsibility of
the iommu driver to remove devices from the group
(iommu_group_remove_device).
IOMMU groups also include a userspace representation in sysfs under
/sys/kernel/iommu_groups. When allocated, each group is given a
dynamically assign ID (int). The ID is managed by the core IOMMU group
code to support multiple heterogeneous iommu drivers, which could
potentially collide in group naming/numbering. This also keeps group
IDs to small, easily managed values. A directory is created under
/sys/kernel/iommu_groups for each group. A further subdirectory named
"devices" contains links to each device within the group. The iommu_group
file in the device's sysfs directory, which formerly contained a group
number when read, is now a link to the iommu group. Example:
$ ls -l /sys/kernel/iommu_groups/26/devices/
total 0
lrwxrwxrwx. 1 root root 0 Apr 17 12:57 0000:00:1e.0 ->
../../../../devices/pci0000:00/0000:00:1e.0
lrwxrwxrwx. 1 root root 0 Apr 17 12:57 0000:06:0d.0 ->
../../../../devices/pci0000:00/0000:00:1e.0/0000:06:0d.0
lrwxrwxrwx. 1 root root 0 Apr 17 12:57 0000:06:0d.1 ->
../../../../devices/pci0000:00/0000:00:1e.0/0000:06:0d.1
$ ls -l /sys/kernel/iommu_groups/26/devices/*/iommu_group
[truncating perms/owner/timestamp]
/sys/kernel/iommu_groups/26/devices/0000:00:1e.0/iommu_group ->
../../../kernel/iommu_groups/26
/sys/kernel/iommu_groups/26/devices/0000:06:0d.0/iommu_group ->
../../../../kernel/iommu_groups/26
/sys/kernel/iommu_groups/26/devices/0000:06:0d.1/iommu_group ->
../../../../kernel/iommu_groups/26
Groups also include several exported functions for use by user level
driver providers, for example VFIO. These include:
iommu_group_get(): Acquires a reference to a group from a device
iommu_group_put(): Releases reference
iommu_group_for_each_dev(): Iterates over group devices using callback
iommu_group_[un]register_notifier(): Allows notification of device add
and remove operations relevant to the group
iommu_group_id(): Return the group number
This patch also extends the IOMMU API to allow attaching groups to
domains. This is currently a simple wrapper for iterating through
devices within a group, but it's expected that the IOMMU API may
eventually make groups a more integral part of domains.
Groups intentionally do not try to manage group ownership. A user
level driver provider must independently acquire ownership for each
device within a group before making use of the group as a whole.
This may change in the future if group usage becomes more pervasive
across both DMA and IOMMU ops.
Groups intentionally do not provide a mechanism for driver locking
or otherwise manipulating driver matching/probing of devices within
the group. Such interfaces are generic to devices and beyond the
scope of IOMMU groups. If implemented, user level providers have
ready access via iommu_group_for_each_dev and group notifiers.
iommu_device_group() is removed here as it has no users. The
replacement is:
group = iommu_group_get(dev);
id = iommu_group_id(group);
iommu_group_put(group);
