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).

+ * 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.

1) Intel Local Management Service (Intel LMS)
- Applications running locally on the platform communicate with
- Intel AMT Release 2.0 and later releases in the same way
- that network applications do via SOAP over HTTP (deprecated
- starting with Release 6.0) or with WS-Management over SOAP over
- HTTP. which means that some Intel AMT feature can be access
- from a local application using same Network interface as for
- remote application.
-
- When a local application sends a message addressed to the local
- Intel AMT host name, the Local Manageability Service (LMS),
- which listens for traffic directed to the host name, intercepts
- the message and routes it to the Intel Management Engine Interface.

-IT knows when a platform crashes even when there is a hard failure
-on the host.
-The AMT Watchdog is composed of two parts:
- 1) FW Feature - that receives the heartbeats
- and sends an event when the heartbeats stop.
- 2) MEI driver – connects to the watchdog (WD) feature,
- configures the watchdog and sends the heartbeats.
-
-The MEI driver configures the Watchdog to expire by default
-every 120sec unless set by the user using module parameters.
-The Driver then sends heartbeats every 2sec.
+to any subsciber to this event. This mechanism means that
+IT knows when a platform crashes even when there is a hard failureon the host.
-If WD feature does not exist (i.e. the connection failed),
-the MEI driver will disable the sending of heartbeats.
+The Intel AMT Watchdog is composed of two parts:

-Module Parameters
-=================
-watchdog_timeout - the user can use this module parameter
-to change the watchdog timeout setting.
+The Intel MEI driver uses the kernel watchdog to configure the Intel AMT
+Watchdog and to send heartbeats to it. The default timeout of the
+watchdog is 120 seconds.
-This value sets the Intel AMT watchdog timeout interval in seconds;
-the default value is 120sec.
-in order to disable the watchdog activites set the value to 0.
-Normal values should be between 120 and 65535
+If the Intel AMT Watchdog feature does not exist (i.e. the connection failed),
+the Intel MEI driver will disable the sending of heartbeats.
Supported Chipsets:

+TODO
+. check error handling/cleanup paths
+. add drm_plane / overlay support
+. add video decode/encode support (via syslink3 + codec-engine)
+. still some rough edges with flipping.. event back to userspace should
+ really come after VSYNC interrupt
+. where should we do eviction (detatch_pages())? We aren't necessarily
+ accessing the pages via a GART, so maybe we need some other threshold
+ to put a cap on the # of pages that can be pin'd. (It is mostly only
+ of interest in case you have a swap partition/file.. which a lot of
+ these devices do not.. but it doesn't hurt for the driver to do the
+ right thing anyways.)
+ . Use mm_shrinker to trigger unpinning pages. Need to figure out how
+ to handle next issue first (I think?)
+ . Note TTM already has some mm_shrinker stuff.. maybe an argument to
+ move to TTM? Or maybe something that could be factored out in common?
+. GEM/shmem backed pages can have existing mappings (kernel linear map,
+ etc..), which isn't really ideal.
+. Revisit GEM sync object infrastructure.. TTM has some framework for this
+ already. Possibly this could be refactored out and made more common?
+ There should be some way to do this with less wheel-reinvention.
+. Review DSS vs KMS mismatches. The omap_dss_device is sort of part encoder,
+ part connector. Which results in a bit of duct tape to fwd calls from
+ encoder to connector. Possibly this could be done a bit better.
+. Solve PM sequencing on resume. DMM/TILER must be reloaded before any
+ access is made from any component in the system. Which means on suspend
+ CRTC's should be disabled, and on resume the LUT should be reprogrammed
+ before CRTC's are re-enabled, to prevent DSS from trying to DMA from a
+ buffer mapped in DMM/TILER before LUT is reloaded.
+. Add debugfs information for DMM/TILER
+
+Userspace:

-This is a driver for NAND controller of Intel Moorestown platform.
-
-This driver is a standalone linux block device driver, it acts as if it's a normal hard disk.
-It includes three layer:
- block layer interface - file ffsport.c
- Flash Translation Layer (FTL) - file flash.c (implement the NAND flash Translation Layer, includs address mapping, garbage collection, wear-leveling and so on)
- Low level layer - file lld_nand.c/lld_cdma.c/lld_emu.c (which implements actual controller hardware registers access)
-
-This driver can be build as modules or build-in.
-
-Dependency:
-This driver has dependency on IA Firmware of Intel Moorestown platform.
-It need the IA Firmware to create the block table for the first time.
-And to validate this driver code without IA Firmware, you can change the
-macro AUTO_FORMAT_FLASH from 0 to 1 in file spectraswconfig.h. Thus the
-driver will erase the whole nand flash and create a new block table.
-
-TODO:
- - Enable Command DMA feature support
- - lower the memory footprint
- - Remove most of the unnecessary global variables
- - Change all the upcase variable / functions name to lowercase
- - Some other misc bugs
-
-Please send patches to:
- Greg Kroah-Hartman <gregkh@suse.de>

-And Cc to: Gao Yunpeng <yunpeng.gao@intel.com>

TODO
====
-API
-===
-
-Master window broadcast select mask
------------------------------------
-
-API currently provides no method to set or get Broadcast Select mask. Suggest
-somthing like:
-
- int vme_master_bmsk_set (struct vme_resource *res, int mask);
- int vme_master_bmsk_get (struct vme_resource *res, int *mask);
-
-
-Interrupt Generation
---------------------
-
-Add optional timeout when waiting for an IACK.
-
-
-CR/CSR Buffer
--------------
-
-The VME API provides no functions to access the buffer mapped into the CR/CSR
-space.
-
-
-Mailboxes
----------
-
-Whilst not part of the VME specification, they are provided by a number of
-chips. They are currently not supported at all by the API.
-
-
-Core
-====
-
-- Improve generic sanity checks (Such as does an offset and size fit within a
- window and parameter checking).
-
-Bridge Support
-==============
-
-Tempe (tsi148)
---------------
-
-- 2eSST Broadcast mode.
-- Mailboxes unsupported.
-- Improve error detection.
-- Control of prefetch size, threshold.
-- Arbiter control
-- Requestor control
-
-Universe II (ca91c142)
-----------------------
-
-- Mailboxes unsupported.
-- Error Detection.
-- Control of prefetch size, threshold.
-- Arbiter control
-- Requestor control
-- Slot detection
-
-Universe I (ca91x042)
----------------------
-
-Currently completely unsupported.
+- Add one or more device drivers which use the VME framework.
