The Silicom Bypass Network Interface Cards (NICs) are network cards with
paired ports (2 or 4). The pairs either act as a "wire" allowing the
network packets to pass or insert the device in between the two ports.
When paired with the on-board hardware watchdog or other failsafe, they
provide high availability for the network in the face of software
outages or maintenance.

[V2: rebased to apply to 20120905 staging-next, no other changes]
The original zcache in staging is a "demo" version, and this is a massive
rewrite. This was intended to result in a merged zcache and ramster, but
that option has been blocked so, to continue forward progress on ramster
and future related projects, only ramster moves to the new codebase.
To differentiate between the old demo zcache and the rewrite, we refer
to the latter as zcache2, config'd as CONFIG_ZCACHE2. Zcache and zcache2
cannot be built in the same kernel, so CONFIG_ZCACHE2 implies !CONFIG_ZCACHE.
This developer still has hope that zcache and zcache2 will be merged
into one codebase. Until then, zcache2 can be considered a one-node
version of ramster.
No history of changes was recorded during the zcache2 rewrite and recreating
a sane one would be a Sisyphean task but, since ramster is still in
staging and has been unchanged since it was merged, presumably this
is acceptable.
This commit also provides the hooks in zcache2 for ramster, but all
ramster-specific code is provided in a separate commit.
Some of the highlights of this rewritten codebase for zcache2:
(Note: If you are not familiar with the tmem terminology, you can review
it here: http://lwn.net/Articles/454795/ )
1. Merge of "demo" zcache and the v1.1 version of zcache in ramster. Zcache
and ramster had a great deal of duplicate code which is now merged.
In essence, zcache2 *is* ramster but with no remote machine available,
but !CONFIG_RAMSTER will avoid compiling lots of ramster-specific code.
2. Allocator. Previously, persistent pools used zsmalloc and ephemeral pools
used zbud. Now a completely rewritten zbud is used for both. Notably
this zbud maintains all persistent (frontswap) and ephemeral (cleancache)
pageframes in separate queues in LRU order.
3. Interaction with page allocator. Zbud does no page allocation/freeing,
it is done entirely in zcache2 where it can be tracked more effectively.
4. Better pre-allocation. Previously, on put, if a new pageframe could not be
pre-allocated, the put would fail, even if the allocator had plenty of
partial pages where the data could be stored; this is now fixed.
5. Ouroboros ("eating its own tail") allocation. If no pageframe can be
allocated AND no partial pages are available, the least-recently-used
ephemeral pageframe is reclaimed immediately (including flushing tmem
pointers to it) and re-used. This ensures that most-recently-used
cleancache pages are more likely to be retained than LRU pages and also
that, as in the core mm subsystem, anonymous pages have a higher priority
than clean page cache pages.
6. Zcache and zbud now use debugfs instead of sysfs. Ramster uses debugfs
where possible and sysfs where necessary. (Some ramster configuration
is done from userspace so some sysfs is necessary.)
7. Modularization. As some have observed, the monolithic zcache-main.c code
included zbud code, which has now been separated into its own code module.
Much ramster-specific code in the old ramster zcache-main.c has also been
moved into ramster.c so that it does not get compiled with !CONFIG_RAMSTER.
8. Rebased to 3.5.
This new codebase also provides hooks for several future new features:
A. WasActive patch, requires some mm/frontswap changes previously posted.
A new version of this patch will be provided separately.
See ifdef __PG_WAS_ACTIVE
B. Exclusive gets. It seems tmem _can_ support exclusive gets with a
minor change to both zcache2 and a small backwards-compatible change
to frontswap.c. Explanation and frontswap patch will be provided
separately. See ifdef FRONTSWAP_HAS_EXCLUSIVE_GETS
C. Ouroboros writeback. Since persistent (frontswap) pages may now also be
reclaimed in LRU order, the foundation is in place to properly writeback
these pages back into the swap cache and then the swap disk. This is still
under development and requires some other mm changes which are prototyped.
See ifdef FRONTSWAP_HAS_UNUSE.
A new feature that desperately needs attention (if someone is looking for
a way to contribute) is kernel module support. A preliminary version of
a patch was posted by Erlangen University and needs to be integrated and
tested for zcache2 and brought up to kernel standards.
If anybody is interested on helping out with any of these, let me know!

gap voltage and temperature sensor (VBGAPTS) module. The band
gap provides current and voltage reference for its internal
circuits and other analog IP blocks. The analog-to-digital

to the silicon temperature.
This patch provides a platform driver which expose this feature.

The Configurable Gadget driver is a composite driver that allows
userspace to change at runtime the list of functions enabled in
its configuration and to configure these functions. It supports
multiple functions: acm, rndis, and mass storage.
It is usually controlled by a daemon that changes the configuration
based on user settings. For example, rndis is enabled when the user
enables sharing the phone data connection.
As an example on how to use it, the following shell commands will
make the gadget disconnect from the host and make it be re-enumerated
as a composite with 1 rndis and 2 acm interfaces, and a different
product id:
echo 0 > /sys/class/ccg_usb/ccg0/enable
echo rndis,acm > /sys/class/ccg_usb/ccg0/functions
echo 2 > /sys/class/ccg_usb/ccg0/f_acm/instances
echo -n 0x2d01 > /sys/module/g_ccg/parameters/idProduct
echo 1 > /sys/class/ccg_usb/ccg0/enable
The driver requires a gadget controller that supports software
control of the D+ pullup and the controller driver must support
disabling the pullup during composite_bind.

Pull nouveau destaging + Kelper modesetting support from Dave Airlie:
"This pull request is unexpected and not something I had mentioned

So NVIDIA announced new Kepler GPUs this morning, and Ben has killed
himself getting modesetting support for them together to have on

gone in, however this pull contains a few more pieces along with the
final enables so the driver binds to the new Kepler cards. Its quite
amazing that nouveau can support a GPU on its launch day even if its
just unaccelerated modesetting, and I'd like to have support in the
next kernel.
In order to sweeten the deal, Ben has also requested nouveau destage
and become ABI stable, the only change is the version number bump
which he prepared userspace for quite a long time ago. The driver
hasn't broken ABI since that one big break that caused a lot of fuss.
It's also quite a small set of code, and not likely to break anything."

A DRM display driver for TI OMAP platform. Similar to omapfb (fbdev)
and omap_vout (v4l2 display) drivers in the past, this driver uses the
DSS2 driver to access the display hardware, including support for
HDMI, DVI, and various types of LCD panels. And it implements GEM
support for buffer allocation (for KMS as well as offscreen buffers
used by the xf86-video-omap userspace xorg driver).
The driver maps CRTCs to overlays, encoders to overlay-managers, and
connectors to dssdev's. Note that this arrangement might change slightly
when support for drm_plane overlays is added.
For GEM support, non-scanout buffers are using the shmem backed pages
provided by GEM core (In drm_gem_object_init()). In the case of scanout
buffers, which need to be physically contiguous, those are allocated
with CMA and use drm_gem_private_object_init().
See userspace xorg driver:
git://github.com/robclark/xf86-video-omap.git

v2: http://patches.linaro.org/4156/
v3: http://patches.linaro.org/4688/
v4: http://patches.linaro.org/4791/
History:
v5: move headers from include/drm at Greg KH's request, minor rebasing
on 3.2-rc1, pull in private copies of drm_gem_{get,put}_pages()
because "drm/gem: add functions to get/put pages" patch is not
merged yet
v4: bit of rework of encoder/connector _dpms() code, modeset_init()
rework to not use nested functions, update TODO.txt
v3: minor cleanups, improved error handling for dev_load(), some minor
API changes that will be needed later for tiled buffer support
v2: replace omap_vram with CMA for scanout buffer allocation, remove
unneeded functions, use dma_addr_t for physical addresses, error
handling cleanup, refactor attach/detach pages into common drm
functions, split non-userspace-facing API into omap_priv.h, remove
plugin API

To quote Alan:
Moorestown/Oaktrail has appeared only in the PC like form so the
following bits of staging can be binned:
drivers/staging/spectra
so let's delete it.

In practice, it is being hard to distinguish when a patch
should go to staging tree or to the media tree. Better
to distinguish it, by putting the media drivers at a
separate staging directory. Newer staging drivers that include
anything with "dvb*.h", "v4l2*.h" or "videodev2.h" should
go to the drivers/staging/media tree.

Fix compilation errors in the USB driver by replacing usb_buffer_free(),
usb_buffer_alloc() with usb_free_coherent() and usb_alloc_coherent().
Add entries for the driver in parent Makefile and Kconfig.
