The MPT - Memory Protection Table - is used by both memory windows and
memory regions. Hence, all MPT references are relevant for both types
of memory objects. Rename the relevant functions to start with mpt_
instead of the current mr_ prefix.

Pull sound updates from Takashi Iwai:
"The biggest change in this update is the unification of HD-audio codec
parsers. Now the HD-audio codec is parsed in a generic parser code
which is invoked by each HD-audio codec driver.
Some background information is found in David Henningsson's blog
entry:
http://voices.canonical.com/david.henningsson/2013/01/18/upcoming-changes-to-the-intel-hda-drivers/
Other than that, some random updates/fixes like USB-audio and a bunch
of small AoC updates as usual.
Highlights:
- Unification of HD-audio parser code (aka generic parser)
- Support of new Intel HD-audio controller, new IDT codecs
- Fixes for HD-audio HDMI audio hotplug
- Haswell HDMI audio fixup
- Support of Creative CA0132 DSP code
- A few fixes of HDSP driver
- USB-audio fix for Roland A-PRO, M-Audio FT C600
- Support PM for aloop driver (and fixes Oops)
- Compress API updates for gapless playback support
For ASoC part:
- Support for a wider range of hardware in the compressed stream code
- The ability to mute capture streams as well as playback streams
while inactive
- DT support for AK4642, FSI, Samsung I2S and WM8962
- AC'97 support for Tegra
- New driver for max98090, replacing the stub which was there
- A new driver from Dialog
Note that due to dependencies, DTification of DMA support for Samsung
platforms (used only by the and I2S driver and SPI) is merged here as
well."
Fix up trivial conflict in drivers/spi/spi-s3c64xx.c due to removed code
being changed.

APEI GHES and i7core_edac/sb_edac currently can be loaded at
the same time, but those are Highlander modules:
"There can be only one".
There are two reasons for that:
1) Each driver assumes that it is the only one registering at
the EDAC core, as it is driver's responsibility to number
the memory controllers, and all of them start from 0;
2) If BIOS is handling the memory errors, the OS can't also be
doing it, as one will mangle with the other.
So, we need to add an module owner's lock at the EDAC core,
in order to avoid having two different modules handling memory
errors at the same time. The best way for doing this lock seems
to use the driver's name, as this is unique, and won't require
changes on every driver.

be initialized earlier, otherwise the ghes_edac driver initializes

Create a debugfs direcotry i5100_edac/mcX for each memory controller and
add nodes to control how fault injection is preformed.
After configuring an injection using inject_channel, inject_deviceptr1,
inject_deviceptr2, inject_eccmask1, inject_eccmask2 and inject_hlinesel
trigger the injection by writing anything to inject_enable.
Example of a CE injection:
echo 0 > /sys/kernel/debug/i5100_edac/mc0/inject_channel
echo 1 > /sys/kernel/debug/i5100_edac/mc0/inject_hlinesel
echo 61440 > /sys/kernel/debug/i5100_edac/mc0/inject_eccmask1
echo 1 > /sys/kernel/debug/i5100_edac/mc0/inject_enable
Example of UE injection:
echo 0 > /sys/kernel/debug/i5100_edac/mc0/inject_channel
echo 2 > /sys/kernel/debug/i5100_edac/mc0/inject_hlinesel
echo 65535 > /sys/kernel/debug/i5100_edac/mc0/inject_eccmask1
echo 65535 > /sys/kernel/debug/i5100_edac/mc0/inject_eccmask2
echo 17 > /sys/kernel/debug/i5100_edac/mc0/inject_deviceptr1
echo 0 > /sys/kernel/debug/i5100_edac/mc0/inject_deviceptr2
echo 1 > /sys/kernel/debug/i5100_edac/mc0/inject_enable
Sometimes it is needed to enable the injection more then once (echo to
the inject_enable node) for the injection to happen, I am not sure why.

After running a series of tests on an HP DL320, filled with different
memory sizes, it was noticed that, when filled with just one DIMM
on such hardware, the driver wrongly detects twice the memory, and
thinks that both channels 0 and 1 are filled.
It seems to be partially caused by the BIOS and partially by the driver.
The i3200_edac current logic would be working fine if the BIOS were
disabling the unused second channel when just one DIMM is connected,
in order to do power-saving, as recommended on this chipset's datasheet.
However, the BIOS on this particular machine doesn't do it:
[ 16.741421] EDAC DEBUG: how_many_channels: In dual channel mode
[ 16.741424] EDAC DEBUG: how_many_channels: 2 DIMMS per channel enabled
So, the driver were assuming that 2 channels are enabled (well, they are,
but the second is unused).
Combined with that, I found two issues at the logic that creates the
EDAC data, that were failing when the two channels are not equally
filled (AFAICT, that happens only when just 1 DIMM is plugged).
The first one is that a 0 at DRB means that nothing is filled. The
driver's logic, however, do some calculation with that.
The second one is that the logic that fills the DIMM data currently
assumes that both channels are equally filled.
I tested the system already with the current configuration and my
patch and it is now working fine. So, for a 2R single DIMM 2Gb memory
at dimm slot 01 (channel 0), it is now displaying:
[ 16.741406] EDAC DEBUG: i3200_get_drbs: drb[0][0] = 16, drb[1][0] = 0
[ 16.741410] EDAC DEBUG: i3200_get_drbs: drb[0][1] = 32, drb[1][1] = 0
[ 16.741413] EDAC DEBUG: i3200_get_drbs: drb[0][2] = 32, drb[1][2] = 0
[ 16.741416] EDAC DEBUG: i3200_get_drbs: drb[0][3] = 32, drb[1][3] = 0
...
[ 16.741896] EDAC DEBUG: i3200_probe1: csrow 0, channel 0, size = 1024 Mb
[ 16.741899] EDAC DEBUG: i3200_probe1: csrow 1, channel 0, size = 1024 Mb
and the corresponding sysfs nodes are now properly filled.

Currently, it is not possible to know, when debug is enabled,
if the driver is using 2 DIMMS per channel mode or not. It is
not possible to know the values of the drbs registers, used
to identify the memory rank sizes.

If an fsync occurs on a read-only array, we need to send a
completion for the IO and may not increment the active IO count.
Otherwise, we hit a bug trace and can't stop the MD array anymore.
By advice of Christoph Hellwig we return success upon a flush
request but we return -EROFS for other writes.
We detect flush requests by checking if the bio has zero sectors.
This patch is suitable to any -stable kernel to which it applies.

Fix a smatch warning caused by an useless pointer check.
The context parameter (aka. ata_dev) will never be NULL until we remove
the acpi notification handler, so it is pointless to check it for NULL.

When the user application sends a ATA_12 or ATA_16 PASSTHROUGH
scsi command, put the task file register in the sense data with the
proper Sense Key. Instead of NO SENSE, set RECOVERED, as
specified in [SAT2]12.2.5 Table 92.
Tested:
Using udev ata_id to generate a passthrough command, IDENTIFY:
before:
sd 0:0:0:0: [sda] CDB: ATA command pass through(12)/Blank: \
a1 08 2e 00 01 00 00 00 00 ec 00 00
sd 0:0:0:0: [sda] Sense Key : No Sense [current] [descriptor]
Descriptor sense data with sense descriptors (in hex):

People are playing odd games with IRQF_DISABLED, remove it.
Its not reliable, since shared interrupt lines could disable it for you,
and its possible and allowed for archs to disable IRQs to limit IRQ nesting.
Therefore, simply mandate that _ALL_ IRQ handlers are run with IRQs disabled.
[ This _should_ not break anything, since we've mandated that IRQ handlers
_must_ be able to deal with this for a _long_ time ]
IRQ handlers should be fast, no if buts and any other exceptions. We also have
plenty instrumentation to find any offending IRQ latency sources.
