aa98b772b7 staging: sb105x: delete the driver
It's been marked BROKEN for over a year, and no one has stepped up to do
anything with the code, and no one has complained.  So just delete it.
If someone wants to fix it up and merge it "properly", they can revert
this commit.

dc93c85235 staging: sm7xxfb: remove driver
It hasn't been worked on in a very long time, and the original author
has moved on to a different product as this one is no longer being made.
So remove the driver.  If someone wants to resurect it, and clean it up
and get it merged to the "proper" part of the kernel, this commit can be
reverted.

fea8893da7 Staging wireless driver for 3.14-rc1
Here's a single staging driver for a wireless chipset that has shown up
 in the SteamBox hardware.  It is merged separately from the "main"
 staging pull request to sync up with the wireless api changes that came
 in from the networking tree.
 
 It's self-contained and works for me and others.  Larry will be
 replacing it with a "real" driver for 3.15, but for now this one is
 needed.

cd67e10ac6 zram: promote zram from staging
Zram has lived in staging for a LONG LONG time and have been
fixed/improved by many contributors so code is clean and stable now.  Of
course, there are lots of product using zram in real practice.

The major TV companys have used zram as swap since two years ago and
recently our production team released android smart phone with zram
which is used as swap, too and recently Android Kitkat start to use zram
for small memory smart phone.  And there was a report Google released
their ChromeOS with zram, too and cyanogenmod have been used zram long
time ago.  And I heard some disto have used zram block device for tmpfs.
In addition, I saw many report from many other peoples.  For example,
Lubuntu start to use it.

The benefit of zram is very clear.  With my experience, one of the
benefit was to remove jitter of video application with backgroud memory
pressure.  It would be effect of efficient memory usage by compression
but more issue is whether swap is there or not in the system.  Recent
mobile platforms have used JAVA so there are many anonymous pages.  But
embedded system normally are reluctant to use eMMC or SDCard as swap
because there is wear-leveling and latency issues so if we do not use
swap, it means we can't reclaim anoymous pages and at last, we could
encounter OOM kill.  :(

Although we have real storage as swap, it was a problem, too.  Because
it sometime ends up making system very unresponsible caused by slow swap
storage performance.

Quote from Luigi on Google
 "Since Chrome OS was mentioned: the main reason why we don't use swap
  to a disk (rotating or SSD) is because it doesn't degrade gracefully
  and leads to a bad interactive experience.  Generally we prefer to
  manage RAM at a higher level, by transparently killing and restarting
  processes.  But we noticed that zram is fast enough to be competitive
  with the latter, and it lets us make more efficient use of the
  available RAM.  " and he announced.
http://www.spinics.net/lists/linux-mm/msg57717.html

Other uses case is to use zram for block device.  Zram is block device
so anyone can format the block device and mount on it so some guys on
the internet start zram as /var/tmp.
http://forums.gentoo.org/viewtopic-t-838198-start-0.html

Let's promote zram and enhance/maintain it instead of removing.

bcf1647d08 zsmalloc: move it under mm
This patch moves zsmalloc under mm directory.

Before that, description will explain why we have needed custom
allocator.

Zsmalloc is a new slab-based memory allocator for storing compressed
pages.  It is designed for low fragmentation and high allocation success
rate on large object, but <= PAGE_SIZE allocations.

zsmalloc differs from the kernel slab allocator in two primary ways to
achieve these design goals.

zsmalloc never requires high order page allocations to back slabs, or
"size classes" in zsmalloc terms.  Instead it allows multiple
single-order pages to be stitched together into a "zspage" which backs
the slab.  This allows for higher allocation success rate under memory
pressure.

Also, zsmalloc allows objects to span page boundaries within the zspage.
This allows for lower fragmentation than could be had with the kernel
slab allocator for objects between PAGE_SIZE/2 and PAGE_SIZE.  With the
kernel slab allocator, if a page compresses to 60% of it original size,
the memory savings gained through compression is lost in fragmentation
because another object of the same size can't be stored in the leftover
space.

This ability to span pages results in zsmalloc allocations not being
directly addressable by the user.  The user is given an
non-dereferencable handle in response to an allocation request.  That
handle must be mapped, using zs_map_object(), which returns a pointer to
the mapped region that can be used.  The mapping is necessary since the
object data may reside in two different noncontigious pages.

The zsmalloc fulfills the allocation needs for zram perfectly

3c05bedb5f Staging: rtl8812ae: Add Realtek 8821 PCI WIFI driver
This comes directly from the Realtek tarball, filename:
	wifi_driver_8821ae_0018.1129.2013.tar.gz

I mushed the three modules (btcoexist, rtlwifi and rtl8821ae) together
into one, in order to make it all build as one stand-alone module.
After the btcoexist driver gets merged upstream, I'll pull it out of
here, and will continue to work on removing this version of rtlwifi in
order to use the in-kernel one.

There are still many rts5208/5288 card readers being used, but no
drivers are supported them in kernel now. This driver can make a

Many other rts-series card reader are supported by mfd driver, but due
to much difference with others, rts5208/5288 can not add into mfd driver
pretty now, so we provide a separated driver here to support the device.

c63a164271 staging: ktap: add to the kernel tree
This patch introduces ktap to staging tree.

ktap is a new script-based dynamic tracing tool for Linux,
it uses a scripting language and lets users trace the
Linux kernel dynamically. ktap is designed to give
operational insights with interoperability that allow
users to tune, troubleshoot and extend kernel and application.
It's similar with Linux Systemtap and Solaris Dtrace.

ktap have different design principles from Linux mainstream
dynamic tracing language in that it's based on bytecode,
so it doesn't depend upon GCC, doesn't require compiling
kernel module for each script, safe to use in production
environment, fulfilling the embedded ecosystem's tracing needs.

See ktap tutorial for more information:
    http://www.ktap.org/doc/tutorial.html

The merit of putting this software in staging tree is
to make it more possible to get feedback from users
and thus polish the code.

d7e09d0397 staging: add Lustre file system client support
Lustre is the most deployed distributed file system
in the HPC (High Performance Computing) world. The patch
adds its client side support.

The code is not very clean and needs to live in drivers/staging
for some time for continuing cleanup work. See
drivers/staging/lustre/TODO for details.

The code is based on Lustre master commit faefbfc04

f33cb17d1d staging: net: remove pc300 driver
To quote the TODO from staging/net/:

  PC300:

  The driver is very broken and cannot work with the current TTY
  layer. It is inevitable to convert it to the new TTY API. If no
  one steps in to adopt the driver, it will be removed in the 3.7
  release.

Nothing has changed since more than _one_ year on this driver, thus
just remove it since we already moved past 3.7. If somebody steps
up and does a whole rework, he/she, of course, is free to resubmit
it. Since this is the only one in the net directory, we can remove
it as well.

8bb0daffb0 drm/omap: move out of staging
Now that the omapdss interface has been reworked so that omapdrm can use
dispc directly, we have been able to fix the remaining functional kms
issues with omapdrm.  And in the mean time the PM sequencing and many
other of that open issues have been solved.  So I think it makes sense
to finally move omapdrm out of staging.
