Merge branch 'staging-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging 

* 'staging-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (466 commits)
  net/hyperv: Add support for jumbo frame up to 64KB
  net/hyperv: Add NETVSP protocol version negotiation
  net/hyperv: Remove unnecessary kmap_atomic in netvsc driver
  staging/rtl8192e: Register against lib80211
  staging/rtl8192e: Convert to lib80211_crypt_info
  staging/rtl8192e: Convert to lib80211_crypt_data and lib80211_crypt_ops
  staging/rtl8192e: Add lib80211.h to rtllib.h
  staging/mei: add watchdog device registration wrappers
  drm/omap: GEM, deal with cache
  staging: vt6656: int.c, int.h: Change return of function to void
  staging: usbip: removed unused definitions from header
  staging: usbip: removed dead code from receive function
  staging:iio: Drop {mark,unmark}_in_use callbacks
  staging:iio: Drop buffer mark_param_change callback
  staging:iio: Drop the unused buffer enable() and is_enabled() callbacks
  staging:iio: Drop buffer busy flag
  staging:iio: Make sure a device is only opened once at a time
  staging:iio: Disallow modifying buffer size when buffer is enabled
  staging:iio: Disallow changing scan elements in all buffered modes
  staging:iio: Use iio_buffer_enabled instead of open coding it
  ...

Fix up conflict in drivers/staging/iio/adc/ad799x_core.c (removal of
module_init due to using module_i2c_driver() helper, next to removal of
MODULE_ALIAS due to using MODULE_DEVICE_TABLE instead).

NVIDIA compliant embedded controller
Required properties:
- compatible : should be "nvidia,nvec".
- reg : the iomem of the i2c slave controller
- interrupts : the interrupt line of the i2c slave controller
- clock-frequency : the frequency of the i2c bus
- gpios : the gpio used for ec request
- slave-addr: the i2c address of the slave controller

* The lowmemorykiller driver lets user-space specify a set of memory thresholds
* where processes with a range of oom_adj values will get killed. Specify the
* minimum oom_adj values in /sys/module/lowmemorykiller/parameters/adj and the
* number of free pages in /sys/module/lowmemorykiller/parameters/minfree. Both
* files take a comma separated list of numbers in ascending order.
*
* For example, write "0,8" to /sys/module/lowmemorykiller/parameters/adj and
* "1024,4096" to /sys/module/lowmemorykiller/parameters/minfree to kill
* processes with a oom_adj value of 8 or higher when the free memory drops
* below 4096 pages and kill processes with a oom_adj value of 0 or higher
* when the free memory drops below 1024 pages.
*
* The driver considers memory used for caches to be free, but if a large
* percentage of the cached memory is locked this can be very inaccurate
* and processes may not get killed until the normal oom killer is triggered.
