Changes by Devin Heitmueller:
Import the original Abilis Systems as102 driver. The source is unmodified,
with the only changes I've made so far were that I created a Kconfig and
Makefile so that the code builds in a standard v4l-dvb tree.
This driver requires firmware (which Abilis has provided with redistribution
terms which will allow it to be bundled in the Linux distributions). The
firmware can be downloaded from here:
Thanks to Rainer Miethling from PCTV Systems for working to get the driver
released (for use with the PCTV 74e) and Pierrick Hascoet from Abilis for
authoring the driver.
Changes by Piotr Chmura:
- moved the driver from media/dvb to staging/media
- removed Makefile/Kconfig - compilation fails in current tree

Leaving this code enabled breaks the build on some architectures,
and we shouldn't have any floating point math in the kernel, anyway.
These macros need to be re-written, but it's harmless to simply
return zero for now.

In this patch we are actually moving to the ORE.
(Object Raid Engine).
objio_state holds a pointer to an ore_io_state. Once
we have an ore_io_state at hand we can call the ore
for reading/writing. We register on the done path
to kick off the nfs io_done mechanism.
Again for Ease of reviewing the old code is "#if 0"
but is not removed so the diff command works better.
The old code will be removed in the next patch.
fs/exofs/Kconfig::ORE is modified to also be auto-included
if PNFS_OBJLAYOUT is set. Since we now depend on ORE.

For Ease of reviewing I split the move to ore into 3 parts
move to ore 01: ore_layout & ore_components
move to ore 02: move to ORE
move to ore 03: Remove old raid engine
This patch modifies the objio_lseg, layout-segment level
and devices and components arrays to use the ORE types.
Though it will be removed soon, also the raid engine
is modified to actually compile, possibly run, with
the new types. So it is the same old raid engine but
with some new ORE types.
For Ease of reviewing, some of the old code is
"#if 0" but is not removed so the diff command works
better. The old code will be removed in the 3rd patch.

This is part of moving objio_osd to use the ORE.
objlayout_io_state had two functions:
1. It was used in the error reporting mechanism at layout_return.
This function is kept intact.
(Later patch will rename objlayout_io_state => objlayout_io_res)
2. Carrier of rw io members into the objio_read/write_paglist API.
This is removed in this patch.
The {r,w}data received from NFS are passed directly to the
objio_{read,write}_paglist API. The io_engine is now allocating
it's own IO state as part of the read/write. The minimal
functionality that was part of the generic allocation is passed
to the io_engine.
So part of this patch is rename of:
ios->ol_state.foo => ios->foo
At objlayout_{read,write}_done an objlayout_io_state is passed that
denotes the result of the IO. (Hence the later name change).
If the IO is successful objlayout calls an objio_free_result() API
immediately (Which for objio_osd causes the release of the io_state).
If the IO ended in an error it is hanged onto until reported in
layout_return and is released later through the objio_free_result()
API. (All this is not new just renamed and cleaned)

objlayout driver was always returning PNFS_ATTEMPTED from it's
read/write_pagelist operations. Even on error. Fix that.
Start by establishing an error return API from io-engine, by
not returning ssize_t (length-or-error) but returning "int"
0=OK, 0>Error. And clean up all return types in io-engine.
Then if io-engine returned error return PNFS_NOT_ATTEMPTED
to generic layer. (With a dprint)

The EOF calculation was done on .read_pagelist(), cached
in objlayout_io_state->eof, and set in objlayout_read_done()
into nfs_read_data->res.eof.
So set it directly into nfs_read_data->res.eof and avoid
the extra member.

Returning the max traffic classes on get requests simplifies
user space configurations because applications will know
explicitly how many traffic classes can be used.
Typical switch implementations use 2 or 3 traffic classes
so this not seen often today. And user space can learn
the number of traffic classes by return codes but this
allows user space to configure ixgbe correctly at the
start.

Interface fails to obtain link on 82599 SFP in the following scenario:
1. Set advertised speed to GB:
ethtool -s eth0 advertise 0x20
2. Bring interface down
ip link set eth0 down
3. Issue any command that leads to a reset:
ethtool -t eth0
4. Bring link back up:
ip link set eth0 up
Following patch makes sure that the driver flaps the Tx laser every time
ixgbe_start_hw() is called, and not only when the speed is set.

e100 parts don't support vlan offload but they generally do
allow use of vlans in higher software layers via the 8021q module.
That said, there are a couple of really old revisions of e100
hardware that don't even allow the longer frame sizes
required for vlan use with standard MTU.
Use the VLAN_CHALLENGED flag to prevent vlan binding to these
devices.

While back-porting Johannes Weiner's patch "mm: memcg-aware global
reclaim" for an internal effort, we noticed a significant performance
regression during page-reclaim heavy workloads due to high contention of
the ss->id_lock. This lock protects idr map, and serializes calls to
idr_get_next() in css_get_next() (which is used during the memcg hierarchy
walk).
Since idr_get_next() is just doing a look up, we need only serialize it
with respect to idr_remove()/idr_get_new(). By making the ss->id_lock a
rwlock, contention is greatly reduced and performance improves.
Tested: cat a 256m file from a ramdisk in a 128m container 50 times on
each core (one file + container per core) in parallel on a NUMA machine.
Result is the time for the test to complete in 1 of the containers.
Both kernels included Johannes' memcg-aware global reclaim patches.

In testing aio on a fast storage device, I found that the context lock
takes up a fair amount of cpu time in the I/O submission path. The reason
is that we take it for every I/O submitted (see __aio_get_req). Since we
know how many I/Os are passed to io_submit, we can preallocate the kiocbs
in batches, reducing the number of times we take and release the lock.
In my testing, I was able to reduce the amount of time spent in
_raw_spin_lock_irq by .56% (average of 3 runs). The command I used to
test this was:
aio-stress -O -o 2 -o 3 -r 8 -d 128 -b 32 -i 32 -s 16384 <dev>
I also tested the patch with various numbers of events passed to
io_submit, and I ran the xfstests aio group of tests to ensure I didn't
break anything.

This client driver allows you to use a GPIO pin as a source for PPS
signals. Platform data [1] are used to specify the GPIO pin number,
label, assert event edge type, and whether clear events are captured.
This driver is based on the work by Ricardo Martins who submitted an
initial implementation [2] of a PPS IRQ client driver to the linuxpps
mailing-list on Dec 3 2010.
