However PV on HVM guests might have an unitialized xen_start_info, so

A pgoff_t is defined (by default) to have type (unsigned long). On
architectures such as i686 that's a 32-bit type. The ceph address
space code was attempting to produce 64 bit offsets by shifting a
page's index by PAGE_CACHE_SHIFT, but the result was not what was
desired because the shift occurred before the result got promoted
to 64 bits.
Fix this by converting all uses of page->index used in this way to
use the page_offset() macro, which ensures the 64-bit result has the
intended value.
This fixes http://tracker.newdream.net/issues/3112

Upon completion of a MMC_WRITE_MULTIPLE_BLOCK command MMCIF issues an IRQ
with the DTRANE bit set and often with one or several of CMD12 bits set.
If those interrupts are not acknowledged, an additional interrupt can be
produced and will be delivered later, possibly, when the transaction has
already been completed. To prevent this from happening, CMD12 completion
interrupt sources have to be cleared too upon reception of an DTRANE IRQ.

This reverts commit 94c6cee91 (Add check for IDMAC configuration).
Synopsys says that only if internal dmac is not present, optional
external dma interface is present. When internal dmac is present,
'0' value in DMA_INTERFACE of HCON is reasonable. DMA_INTERFACE
indicates external dma interface. And idmac initialization is
prohibited now.
The commit should be reverted since: the check for IDMAC is not
reliable; falling back to PIO would provide awful performance; we
wouldn't expect to see instances of this block without DMA support.

The problem can be easily reproduced using a script that loops
copying a file in an SD card to another place in the same SD card
and its related to read transfers. This only happens with DMA enabled.
This is related to the fact that, when reading, an MMC irq signals
the fact that all data from the SD card has been copied to the
internal buffers. However, it doesn't signal whether the DMA transfer
that is in charge of moving data from these internal buffers to RAM
has finished or not. Thus, calling dmaengine_terminate_all() in the
MMC irq routine can cancel an ongoing DMA transfer leaving some data
in the internal buffers that produces an accumulative effect which,
in the end, blocks a read data transfer forever.
The following patch watches DMA irq for reading and MMC irqs for
writing transfers. The 'dangerous' usage of dmaengine_terminate_all()
is removed and a timeout of 10 seconds is added so that the MMC won't
block forever anymore.

In some cases mmc_suspend_host() is not able to claim the
host and proceed with the suspend process. The core returns
-EBUSY to the host controller driver. Unfortunately, the
host controller driver does not pass on this information
to the PM core and hence the system suspend process continues.
ret = mmc_suspend_host(host->mmc);
if (ret) {
host->suspended = 0;
if (host->pdata->resume) {
ret = host->pdata->resume(dev, host->slot_id);
The return status from mmc_suspend_host() is overwritten by return
status from host->pdata->resume. So the original return status is lost.
In these cases the MMC core gets to an unexpected state
during resume and multiple issues related to MMC crop up.
1. Host controller driver starts accessing the device registers
before the clocks are enabled which leads to a prefetch abort.
2. A file copy thread which was launched before suspend gets
stuck due to the host not being reclaimed during resume.
To avoid such problems pass on the -EBUSY status to the PM core
from the host controller driver. With this change, MMC core
suspend might still fail but it does not end up making the
system unusable. Suspend gets aborted and the user can try
suspending the system again.

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

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.

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.
