With data-integrity digest enabled, double-check on the sending side
for modifications by upper layers of buffers under write back,
so we can tell it appart from corruption on the "wire".

When converting bits (4k resolution, still) to kB, we shift left. If it
was a large number of bits on a 32bit box (>= 4 TiB storage), we may
wrap the 32bit unsigned long base type, resulting in incorrect display.

For a partial (resumed) online-verify, initialize rs_total not to total
bits, but to number of bits to check in this run, to match the meaning
rs_total has for actual resync.

For network hickups during online-verify, on the next verify
triggered, we by default want to resume where it left off.
After any replication link interruption, there will be a (possibly
empty) resync. Do not reset online-verify start sector if some resync
completed, that would defeats the purpose.
Only reset the start sector once a verify run is completed.

Use tables to list the count of fan and temperature inputs for all
supported chips, almost similar to (but more simple than) what is
already done for voltage inputs. This avoids repeating the same tests
in different functions, and will make it easier to add support for
chips with a different count of fan or temperature inputs.

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.

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
users decide whether it is needed or not.

This patch adds software BCH ECC support to mtd, in order to handle recent
NAND device ecc requirements (4 bits or more).
It does so by adding a new ecc mode (NAND_ECC_SOFT_BCH) for use by board
drivers, and a new Kconfig option to enable BCH support. It relies on the
generic BCH library introduced in a previous patch.
When a board driver uses mode NAND_ECC_SOFT_BCH, it should also set fields
chip->ecc.size and chip->ecc.bytes to select BCH ecc data size and required
error correction capability. See nand_bch_init() documentation for details.
It has been tested on the following platforms using mtd-utils, UBI and
UBIFS: x86 (with nandsim), arm926ejs.

Because malloc/kzalloc may fail, we should check kmalloc/kzalloc return value
in sm_create_sysfs_attributes(), mtd/sm_rtl.c and do error handling.
Meanwhile, we should check sm_create_sysfs_attributes return value.

When page size is 4KiB, ecc.total is set to 8*9, and this causes
nand_write_page_hwecc() to read past the initialized part of the eccpos array,
which corrupts chip->oob_poi with bogus values from ecc_calc.
Fix this by creating a proper nand_ecclayout for 4KiB flashes.

The DaVinci NAND driver was including the mach-types.h header
file.
This prevented the DaVinci NAND driver from getting used
in a DSP only device. The linux port on c6x devices can make
use of the same driver and does not define a corresponding
header file.
This header file was required in the driver because earlier there was code
dependent on a machine_* check. This piece of code has now been factored out
and is in arch/arm/mach-davinci/aemif.c
Thus removing the header file is harmless

OMAP-L137/AM17x has limited number of dedicated EMIFA
address pins, enough to interface directly to an SDRAM.
If a device such as an asynchronous flash needs to be
attached to the EMIFA, then either GPIO pins or a chip
select may be used to control the flash device's upper
address lines.
This patch adds support for the NOR flash on the OMAP-L137/
AM17x user interface daughter board using the latch-addr-flash
MTD mapping driver which allows flashes to be partially
physically addressed. The upper address lines are set by
a board specific code which is a separate patch.

By default mtd_speedtest uses all the eraseblocks of the
MTD partition being tested. For large partitions a
smaller number is sufficient and makes running the test
quicker. For that reason, add a parameter 'count' to
specify the maximum number of eraseblocks to use for
testing.

In onenand_verify function the address can be writepage non-aligned.
When a page is read for comparing the right offset should be used
for "this->verify_buf" to get the right matching with compared
"buf" buffer.
