Linus Torvalds 46f7b63556 Staging drivers patches for 3.20-rc1
Here's the big staging driver tree update for 3.20-rc1.  Lots of little
 things in here, adding up to lots of overall cleanups.  The IIO driver
 updates are also in here as they cross the staging tree boundry a lot.
 I2O has moved into staging as well, as a plan to drop it from the tree
 eventually as that's a dead subsystem.
 
 All of this has been in linux-next with no reported issues for a while.

Alan Cox 2cbf7fe2d5 i2o: move to staging
The I2O layer deals with a technology that to say the least didn't catch on
in the market.

The only relevant products are some of the AMI MegaRAID - which supported I2O
and its native mode (The native mode is faster and runs on Linux), an
obscure crypto ethernet card that's now so many years out of date nobody
would use it, the old DPT controllers, which speak their own dialect and
have their own driver - and ermm.. thats about it.

We also know the code isn't in good shape as recently a patch was proposed
and queried as buggy, which in turn showed the existing code was broken
already by prior "clean up" and nobody had noticed that either.

It's coding style robot code nothing more. Like some forgotten corridor
cleaned relentlessly by a lost Roomba but where no user has trodden in years.

Move it to staging and then to /dev/null.

The headers remain as they are shared with dpt_i2o.

Linus Torvalds dab363f938 Staging patches for 3.19-rc1
Here's the big staging tree pull request for 3.19-rc1.
 
 We continued to delete more lines than were added, always a good thing,
 but not at a huge rate this release, only about 70k lines removed
 overall mostly from removing the horrid bcm driver.
 
 Lots of normal staging driver cleanups and fixes all over the place,
 well over a thousand of them, the shortlog shows all the horrid details.
 
 The "contentious" thing here is the movement of the Android binder code
 out of staging into the "real" part of the kernel.  This is code that
 has been stable for a few years now and is working as-is in the tens of
 millions of devices with no issues.  Yes, the code is horrid, and the
 userspace api leaves a lot to be desired, but it's not going to change
 due to legacy issues that we have no control over.  Because so many
 devices and companies rely on this, and the code is stable, might as
 well promote it out of staging.
 
 This was all discussed at the Linux Plumbers conference, and everyone
 participating agreed that this was the best way forward.
 
 There is work happening to replace the binder code with something new
 that is happening right now, but I don't expect to see the results of
 that work for another year at the earliest.  If that ever happens, and
 Android switches over to it, I'll gladly remove this version.
 
 As for maintainers, I'll be glad to maintain this code, I've been doing
 it for the past few years with no problems.  I'll send a MAINTAINERS
 entry for it before 3.19-final is out, still need to talk to the Google
 developers about if they are willing to help with it or not, last I
 checked they were, which was good.
 
 All of these patches have been in linux-next for a while with no
 reported issues.

Philipp Zabel 6556f7f82b drm: imx: Move imx-drm driver out of staging
The imx-drm driver was put into staging mostly for the following reasons,
all of which have been addressed or superseded:
 - convert the irq driver to use linear irq domains
 - work out the device tree bindings, this lead to the common of_graph
   bindings being used
 - factor out common helper functions, this mostly resulted in the
   component framework and drm of_graph helpers.

Before adding new fixes, and certainly before adding new features,
move it into its proper place below drivers/gpu/drm.

Magnus Damm 382063d91e staging: board: Initial board staging support
Add staging board base support to allow continuous upstream
in-tree development and integration of platform devices.

Helps developers integrate devices as platform devices for
device drivers that only provide platform device bindings.
This in turn allows for incremental development of both
hardware feature support and DT binding work in parallel.

Two separate pieces of board staging functionality is
provided to ease per-board staging board support:
 - The board_staging() macro allows easy per-board callbacks
 - The board_staging_dt_node_available() provides DT node checking

Tested on the KZM9D board with the emxx_udc staging driver.

It never really got cleaned up properly, and no one is working on it, so
remove it.  If someone wants to pick it up, this can be easily reverted.

Minchan Kim 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.

Minchan Kim 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

Greg Kroah-Hartman 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.
