This reverts commit 144060fee0.
It causes a resume regression for Andi on his Acer Aspire 1830T post
3.1. The screen just stays black after wakeup.
Also, it really looks like the wrong way to suspend and resume perf
events: I think they should be done as part of the CPU suspend and
resume, rather than as a notifier that does smp_call_function().

In the old --stdio interface the annotation is done just after one
selects a symbol, while in --tui, now the default when the required libs
are installed, we annotate all symbols with samples so that when
annotation is asked we see what happened recently on that symbol.
To achieve that the --stdio variant checks if the hist_entry being
processed is the one selected by the user via the 's' hotkey. What
happens now that we share the hist_entry abstractions with 'perf report'
is that for minimizing locking contention multiple rb_trees are used,
one for collecting the samples and other to browse/show them after
resorting it by number of samples and decay them, which is done
periodically.
So the simple test in record_precise_ip doesn't work as we move
hist_entries between those rb_trees. To fix it just check that the
underlying struct symbol associated with those hist_entries is the same.

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.

Add support for the Elgato EyeTV DTT Deluxe. Note that the product name
field has not yet been abstracted out, so it will still identify itself
as a PCTV 74e. The driver was originally built by the chipset manufacturer
so that the product vendor can specify the device name via a #define, but
wasn't setup to support multiple products from the same build of the driver.

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

6561 6471 98% 2.30K 243 27 15552K kmalloc-2048
Over 15MB. slub debug shows that cfq is responsible for almost
all of it:

In scsi_alloc_sdev we do scsi_alloc_queue but if slave_alloc
fails we don't free it with scsi_free_queue.

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)

Returning the max traffic classes on get requests simplifies
