NOTE!
This merge commit was created to fix compilation error. The block
tree was merged upstream and removed the 'elv_queue_empty()'
function which the new 'mtdswap' driver is using. So a simple
merge of the mtd tree with upstream does not compile. And the
mtd tree has already be published, so re-basing it is not an option.
To fix this unfortunate situation, I had to merge upstream into the
mtd-2.6.git tree without committing, put the fixup patch on top of
this, and then commit this. The result is that we do not have commits
which do not compile.
In other words, this merge commit "merges" 3 things: the MTD tree, the
upstream tree, and the fixup patch.
Fix the following compilation warning:
drivers/mtd/mtdswap.c: In function ‘mtdswap_pick_gc_eblk’:
drivers/mtd/mtdswap.c:859: warning: ‘idx’ may be used uninitialized in this function

As Artem Bityutskiy suggested: this option is controversial, as we
do not really have any prove it is useful. And it is too much to have
it as a config parameter. So, better kill it and let the real mtdswap

SDIO IRQs got unmasked on sh-mobile while writing to the

is not implemented on those SoCs and writes to it overwrite the

eliminated access to register above 0xff on sh-mobile, so that this

On sh-mobile platforms the SDHI driver was using the tmio_mmc SD/SDIO
MFD cell driver. Now that the tmio_mmc driver has been split into a
core and a separate MFD glue, we can support SDHI natively without the
need to emulate an MFD controller. This also allows to support systems
with an on-SoC SDHI controller and a separate MFD with a TMIO core.

TMIO MMC chips contain an SD / SDIO IP core from Panasonic, similar to
the one, used in MN5774 and other MN57xx controllers. These IP cores are
included in many multifunction devices, in sh-mobile chips from Renesas,
in the latter case they can also use DMA. Some sh-mobile implementations
also have some other specialities, that MFD-based solutions don't have.
This makes supporting all these features in a monolithic driver inconveniet
and error-prone. This patch splits the driver into 3 parts: the core,
the MFD glue and the DMA support. In case of a modular build, two modules
will be built: mmc_tmio_core and mmc_tmio.

This patch allows transferring of some requests in PIO and some in DMA
mode and defaults to using DMA only for transfers longer than 8 bytes.
This is especially useful with SDIO, which can have lots of 2- and 4-byte

The driver may invalidate the mmc_card->csd when host driver uses dma.

Fix the NO INT in the Multi-BLK IO in SD/MMC, and Multi-BLK read in
SDIO on imx53.
The CMDTYPE of the CMD register (offset 0xE) should be set to "11"
when the STOP CMD12 is issued on imx53 to abort one open ended
multi-blk IO. Otherwise the TC INT wouldn't be generated.
In exact block transfer, the controller doesn't complete the
operations automatically as required at the end of the transfer
and remains on hold if the abort command is not sent on imx53.
As a result, the TC flag is not asserted and SW receives timeout
exception. Set bit1 of Vendor Spec register to fix it.

Commit ddd588b5dd ("oom: suppress nodes that are not allowed from
meminfo on oom kill") moved lib/show_mem.o out of lib/lib.a, which
resulted in build warnings on all architectures that implement their own
versions of show_mem():
lib/lib.a(show_mem.o): In function `show_mem':
show_mem.c:(.text+0x1f4): multiple definition of `show_mem'
arch/sparc/mm/built-in.o:(.text+0xd70): first defined here
The fix is to remove __show_mem() and add its argument to show_mem() in
all implementations to prevent this breakage.
Architectures that implement their own show_mem() actually don't do
anything with the argument yet, but they could be made to filter nodes
that aren't allowed in the current context in the future just like the
generic implementation.

In the event of an unsuccessful query, we should then always report

later generations leaked the return value from the panel probe instead.
