power_supply: allow a power supply to explicitly point to powered device
If a power supply has a scope of "Device", then allow the power supply
to indicate what device it actually powers. This is represented in the
power supply's sysfs directory as a symlink named "powers", which points to
the sysfs directory of the powered device.
If the device has children, then the sub-devices are also powered by
the same power supply.

power_supply: add SCOPE attribute to power supplies
This adds a "scope" attribute to a power_supply, which indicates how
much of the system it powers. It appears in sysfs as "scope" or in
the uevent file as POWER_SUPPLY_SCOPE=. There are presently three
possible values:
Unknown - unknown power topology
System - the power supply powers the whole system
Device - it powers a specific device, or tree of devices
A power supply which doesn't have a "scope" attribute should be assumed to
have "System" scope.
In general, usermode should assume that loss of all System-scoped power
supplies will power off the whole system, but any single one is sufficient
to power the system.

Commit 31a3ddda166cda86d2b5111e09ba4bda5239fae6 introduced
a use after free in virtio-pci. The main issue is
that the release method signals removal of the virtio device,
while remove signals removal of the pci device.
For example, on driver removal or hot-unplug,
virtio_pci_release_dev is called before virtio_pci_remove.
We then might get a crash as virtio_pci_remove tries to use the
device freed by virtio_pci_release_dev.
We allocate/free all resources together with the
pci device, so we can leave the release method empty.

After commit e978aa7d7d57 ("cpuidle: Move dev->last_residency update to
driver enter routine; remove dev->last_state") setting acpi_idle_suspend
to 1 by acpi_processor_suspend() causes the ACPI cpuidle routines to
return error codes continuously, which in turn causes cpuidle to lock up
(hard).
However, acpi_idle_suspend doesn't appear to be useful for any
particular purpose (it's racy and doesn't really provide any real
protection), so it can be removed, which makes the problem go away.

Btrfs: handle bio_add_page failure gracefully in scrub
Currently scrub fails with ENOMEM when bio_add_page fails. Unfortunately
dm based targets accept only one page per bio, thus making scrub always
fails. This patch just submits the current bio when an error is encountered
and starts a new one.

drm: add some comments to drm_wait_vblank and drm_queue_vblank_event
during the review of the fix for locks problems in drm_wait_vblank,
a couple of false concerns were raised about how the drm_vblank_get
and drm_vblank_put are used in this function; it turned out that the
code is correct and that it cannot be simplified
add a few comments to explain non-obvious flows in the code,
to prevent "false alarms" in the future

drm: do not sleep on vblank while holding a mutex
drm_wait_vblank must be DRM_UNLOCKED because otherwise it
will grab the drm_global_mutex and then go to sleep until the vblank
event it is waiting for. That can wreck havoc in the windowing system
because if one process issues this ioctl, it will block all other
processes for the duration of all vblanks between the current and the
one it is waiting for. In some cases it can block the entire windowing
system.
v2: incorporate comments received from Daniel Vetter and
Michel Daenzer.
v3/v4: after a lengty discussion with Daniel Vetter, it was concluded
that the only thing not yet protected with locks and atomic
ops is the write to dev->last_vblank_wait. It's only used in a
debug file in proc, and the current code already employs no
correct locking: the proc file only takes dev->struct_mutex,
whereas drm_wait_vblank implicitly took the drm_global_mutex.
Given all this, it's not worth bothering to try to fix
the locks at this time.

We restore the CRTC, encoder, and connector configurations, but if the
mode set failed, the attached display may have been turned off, so we
need to try set_config again to restore things to the way they were.

drm: serialize access to list of debugfs files
Nouveau, when configured with debugfs, creates debugfs files for every
channel, so structure holding list of files needs to be protected from
simultaneous changes by multiple threads.
Without this patch it's possible to hit kernel oops in
drm_debugfs_remove_files just by running a couple of xterms with
looped glxinfo.

drm/radeon: Make sure CS mutex is held across GPU reset.
This was only the case if the GPU reset was triggered from the CS ioctl,
otherwise other processes could happily enter the CS ioctl and wreak havoc
during the GPU reset.
This is a little complicated because the GPU reset can be triggered from the
CS ioctl, in which case we're already holding the mutex, or from other call
paths, in which case we need to lock the mutex. AFAICT the mutex API doesn't
allow recursive locking or finding out the mutex owner, so we need to handle
this with helper functions which allow recursive locking from the same
process.

ARM: mach-shmobile: cpuidle single/global and last_state fixes
The following commits break cpuidle on SH-Mobile ARM:
46bcfad cpuidle: Single/Global registration of idle states e978aa7 cpuidle: Move dev->last_residency update to driver enter routine; remove dev->last_state
This patch remedies these issues by up-porting the SH-Mobile
code to fit with the above introduced framework changes.
It is worth noting that the new code becomes significantly cleaner,
so these framework changes are very welcome. At the same time this
breakage could probably have been avoided by grepping for "last_state"
and "cpuidle_register_driver".
