Earlier, atmel-mci was adapted to make use of the peripheral DMA
controller (PDC), in case normal DMA wouldn't work.
( http://comments.gmane.org/gmane.linux.kernel.mmc/9403 )
This works OK on ARM platforms (AT91), but it broke the driver
for AVR32, the AP700x. Although the MCI has PDC support, the
connection is not done for AVR chips.
This patch makes the use of PDC depend on !CONFIG_AVR32.

After the latest changes to atmel-mci, it could not be used with
DMA on the AVR32 platform. This patch will allow to use DMA again
and it will avoid access to MCI register ATMCI_DMA.
Even if the IP version is lower than v3xx and doesn't have the DMA
configuration register, DMA transfers can be used with a different
controller than the Atmel AHB DMA one. For instance, some AVR chips
use the Synopsys DesignWare AHB DMA controller.

Platform implementations of dw-mshc controller may choose to extend the
features of the standard dw-mshc controller such as adding additional
clocking options or modifying the bus interface. Support for such
implementation specific extensions can be incorporated into dw_mmc-pltfm,
but including multiple such platform specific implementations would
convolute the existing dw_mmc-pltfm code.
Instead, it would be better to create implementation specific platform
drivers to support implementation specific features. Such platforms
drivers can reuse the existing infrastructure in dw_mmc-pltfm for
resource identification and controller registration and provide support
for implementation specific features. So, allow the infrastructure in
dw_mmc-pltfm to be reused by other implementation specific platform
drivers.

If the write protect pad of the controller is not connected to the write

so that incorrect check for write protection by reading the WRTORT

Enable eMMC background operations (BKOPS) feature.
If URGENT_BKOPS is set after a response, note that BKOPS are required.
Immediately run BKOPS if required. Read/write operations should be
requested during BKOPS(LEVEL-1), then issue HPI to interrupt the
ongoing BKOPS and service the foreground operation.
(This patch only controls the LEVEL2/3.)
When repeating the writing 1GB data, at a certain time, performance is
decreased. At that time, card triggers the Level-3 or Level-2. After
running bkops, performance is recovered.
Future considerations:
* Check BKOPS_LEVEL=1 and start BKOPS in a preventive manner.
* Interrupt ongoing BKOPS before powering off the card.
* How do we get BKOPS_STATUS value (periodically send ext_csd command)?
* If using periodic bkops, also consider runtime_pm control.

The correct syntax for gcc -x is "gcc -x assembler", not
"gcc -xassembler". Even though the latter happens to work, the former
is what is documented in the manual page and thus what gcc wrappers
such as icecream do expect.
This isn't a cosmetic change. The missing space prevents icecream from
recognizing compilation tasks it can't handle, leading to silent kernel
miscompilations.
Besides me, credits go to Michael Matz and Dirk Mueller for
investigating the miscompilation issue and tracking it down to this
incorrect -x parameter syntax.

This is a major rework of the nouveau driver core, to reflect more closely
how the hw is used and to make it easier to implement newer features now
that the GPUs are more clearly understood than when nouveau started.
It also contains a few other bits:
thermal patches
nv41/44 pcie gart fixes
i2c unregistering fixes.

Pull vfs update from Al Viro:
- big one - consolidation of descriptor-related logics; almost all of
that is moved to fs/file.c
(BTW, I'm seriously tempted to rename the result to fd.c. As it is,
we have a situation when file_table.c is about handling of struct
file and file.c is about handling of descriptor tables; the reasons
are historical - file_table.c used to be about a static array of
struct file we used to have way back).
A lot of stray ends got cleaned up and converted to saner primitives,
disgusting mess in android/binder.c is still disgusting, but at least
doesn't poke so much in descriptor table guts anymore. A bunch of
relatively minor races got fixed in process, plus an ext4 struct file
leak.
- related thing - fget_light() partially unuglified; see fdget() in
there (and yes, it generates the code as good as we used to have).
- also related - bits of Cyrill's procfs stuff that got entangled into
that work; _not_ all of it, just the initial move to fs/proc/fd.c and
switch of fdinfo to seq_file.
- Alex's fs/coredump.c spiltoff - the same story, had been easier to
take that commit than mess with conflicts. The rest is a separate
pile, this was just a mechanical code movement.
- a few misc patches all over the place. Not all for this cycle,
there'll be more (and quite a few currently sit in akpm's tree)."
Fix up trivial conflicts in the android binder driver, and some fairly
simple conflicts due to two different changes to the sock_alloc_file()
interface ("take descriptor handling from sock_alloc_file() to callers"
vs "net: Providing protocol type via system.sockprotoname xattr of
/proc/PID/fd entries" adding a dentry name to the socket)

prom_printf() takes printf style arguments. Specifing GCC's format
attribute reveals that there are several wrong usages of prom_printf().
This fixes those wrong format strings and arguments, and also leaves
format attributes in order to detect similar mistakes at compile time.

Hopefully fixed the tlb flush timeout issue. Was able to observe this
condition occur occasionally, and it appears the binary driver doesn't
wait on the old condition either..
Should give 39-bit DMA addressing on the relevant chipsets.

Something seems to be missing in regards to flushing specific ranges of
the TLB. For the moment, flushing the entire thing seems to make it
work alright.
Should give 39-bit DMA addressing on the relevant chipsets.
