This resolves the conflict in the arch/arm/mach-s3c64xx/s3c6400.c file,
and it fixes the build error in the arch/x86/kernel/microcode_core.c
file, that the merge did not catch.The microcode_core.c patch was provided by Stephen Rothwell
who was invaluable in the merge issues involved
with the large sysdev removal process in the driver-core tree.Signed-off-by: Greg Kroah-Hartman

Move invalidate_bdev, block_sync_page into fs/block_dev.c. Export
kill_bdev as well, so brd doesn't have to open code it. Reduce
buffer_head.h requirement accordingly.Removed a rather large comment from invalidate_bdev, as it looked a bit
obsolete to bother moving. The small comment replacing it says enough.Signed-off-by: Nick Piggin

Depending on whether MTD_DOCPROBE_ADVANCED is set or not,
MTD_DOCPROBE_ADDRESS will default to either 0x0000 or 0. That should
lead to (basically) identical code in docprobe.c. The current two
defaults should be merged.And, while we're at it, if MTD_DOCPROBE is set MTD_DOCPROBE_ADDRESS will
always be set. (MTD_DOCPROBE_ADDRESS depends on MTD_DOCPROBE and it has
a default value.) So the check whether CONFIG_MTD_DOCPROBE_ADDRESS is
defined is unnecessary and should be dropped.Signed-off-by: Paul Bolle

Our `ops' information was converted to a local variable recently, and
apparently, old code relied on the fact that the global version was
often left in a valid mode. We can't make this assumption on local
structs, and we shouldn't be relying on a previous state anyway.Instead, we initialize mode to 0 for don't-care situations (i.e., the
operation does not use OOB anyway) and MTD_OPS_PLACE_OOB when we want to
place OOB data.This fixes a bug with nand_default_block_markbad(), where we catch on
the BUG() call in nand_fill_oob():Kernel bug detected[#1]:

parse_mtd_partitions takes a list of partition types; if the driver
isn't loaded, it attempts to load it, and then it grabs the partition
parser. For redboot, the module name is "redboot.ko", while the parser
name is "RedBoot". Since modprobe is case-sensitive, attempting to
modprobe "RedBoot" will never work. I suspect the embedded systems that
make use of redboot just always manually loaded redboot prior to loading
their specific nand chip drivers (or statically compiled it in).Signed-off-by: Andres Salomon

A portion of the `check_pattern()' function is basically a `memcmp()'.
Since it's possible for `memcmp()' to be optimized for a particular
architecture, we should use it instead.Signed-off-by: Brian Norris
Signed-off-by: Artem Bityutskiy -
In rare cases, we are given an unaligned parameter `from' in
`nand_do_read_ops()'. In such cases, we use the page cache
(chip->buffers->databuf) as an intermediate buffer before dumping to the
client buffer. However, there are also cases where this buffer is not
cleanly reusable. In those cases, we need to make sure that we
explicitly invalidate the cache.This patch prevents accidental reusage of the page cache, and for me,
this solves some problems I come across when reading a corrupted BBT
from flash (NAND_BBT_USE_FLASH and NAND_BBT_NO_OOB).Note: the rare "unaligned" case is a result of the extra BBT pattern +
version located in the data area instead of OOB.Also, this patch disables caching on raw reads, since we are reading
without error correction. This is, obviously, prone to errors and should
not be cached.Signed-off-by: Brian Norris
Signed-off-by: Artem Bityutskiy -
Updates to our default function for creating bad block patterns have
broken the "no OOB" feature. The NAND_BBT_NO_OOB option should not be
set while scanning for bad blocks, but we've been passing all BBT
options from nand_chip.bbt_options to the bad block scan. This causes us
to hit the:BUG_ON(bd->options & NAND_BBT_NO_OOB);
in create_bbt() when we scan the flash for bad blocks.
Thus, while it can be legal to set NAND_BBT_NO_OOB in a custom badblock
pattern descriptor (presumably with NAND_BBT_CREATE disabled?), we
should not pass it through in our default function.Also, to help clarify and emphasize that the function creates bad block
patterns only (not, for example, table descriptors for locating
flash-based BBT), I renamed `nand_create_default_bbt_descr' to
`nand_create_badblock_pattern'.Signed-off-by: Brian Norris
Signed-off-by: Artem Bityutskiy -
Because there are so many cases of checking, writing, and re-writing of
the bad block table(s), we might as well wait until the we've settled on
a valid, clean copy of the table. This also prevents us from falsely
incrementing the table version. For example, we may have the following:Primary table, with version 0x02
Mirror table, with version 0x01
Primary table has uncorrectable ECC errorsIf we don't have this fix applied, then we will:
Choose to read the primary table (higher version)
Set mirror table version to 0x02
Read back primary table
Invalidate table because of ECC errors
Retry readback operation with mirror table, now version 0x02
Mirrored table reads cleanly
Writeback BBT to primary table location (with "version 0x02")However, the mirrored table shouldn't have a new version number.
Instead, we actually want:Choose to read the primary table (higher version)
Read back primary table
Invalidate table because of ECC errors
Retry readback with mirror table (version 0x01)
Mirrored table reads cleanly
Set both tables to version 0x01
Writeback BBT to primary table location (version 0x01)Signed-off-by: Brian Norris
Signed-off-by: Artem Bityutskiy -
Now that `read_bbt()' returns ECC error codes properly, we handle those
codes when checking the integrity of our flash-based BBT.The modifications can be described by this new policy:
*) On any uncorrected ECC error, we invalidate the corresponding table
and retry our version-checking integrity logic.
*) On corrected bitflips, we mark both tables for re-writing to flash
(a.k.a. scrubbing).Current integrity checks (i.e., comparing version numbers, etc.) should
take care of all the cases that result in rescanning the device for bad
blocks or falling back to the BBT as found in the mirror descriptor.Signed-off-by: Brian Norris
