d85316ac45 [MTD] fix m25p80 64-bit divisions
MTD has recently been upgraded for 64-bit support, see commit
number 69423d99fc in the
mtd-2.6.git tree (git://git.infradead.org/mtd-2.6.git)
or see this URL:
http://git.infradead.org/mtd-2.6.git?a=commit;h=69423d99fc182a81f3c5db3eb5c140acc6fc64be

Some variables in MTD data structures which were 32-bit
became 64-bit. Namely, the 'size' field in 'struct mtd_info'
and the 'addr'/'len' fields in 'struct erase_info'. This
means we have to use 'do_div' to divide them.

This patch fixes the following linking error:
ERROR: "__umoddi3" [drivers/mtd/devices/m25p80.ko] undefined!

This patch changes divisions of 64-bit variable so that they use
'do_div'. This patch also change some print placeholders to
get rid of gcc warnings.

7854643a91 [MTD] m25p80: chip erase != block erase != sector erase
This fixes broken terminology added in the "m25p80.c erase enhance" patch,
which added a chip erase command but called it "block erase".  There are
already two block erase commands; blocks are 4KiB or 32KiB.  There's also
a sector erase (usually 64 KiB).  Chip erase typically covers Megabytes.

  OPCODE_BE   ==> OPCODE_CHIP_ERASE
  erase_block ==> erase_chip

Commit d0e8c47c58 ("m25p80.c extended jedec
support") added support for extended ids but in the process managed to
break detection of all flashes.

The ext jedec id check was inserted into an if statement that lacked
braces, and it did not add the required braces.  As such, the detection
routine always returns the first entry in the SPI flash list.

8a1a627205 Revert "[MTD] m25p80.c code cleanup"
This reverts commit 75d0ee2202.

Although it seems ObviouslyCorrect™, the spi_write() call uses DMA,
while spi_write_then_read() does not. Since our buffer is on the stack,
we must use the latter even though we don't actually want to read
anything back.

8c64038e4c [MTD] make dataflash write-verify be optional
This adds a WRITE_VERIFY Kconfig option to the DataFlash driver,
closely mirroring the similar NAND and ONENAND options, giving
an option to disable some code that's currently always enabled.

Removing this step probably saves a millisecond or so per page
when writing data, which will add up quickly since these pages
are small (the largest is 1 KiB).  It doesn't seem to add a
lot in terms of reliability, and wouldn't detect errors which
crop up when transferring data to the on-chip SRAM buffer.

771999b65f [MTD] DataFlash: bugfix, binary page sizes now handled
The wrong version of the "teach dataflash about binary density" patch
just got merged (v2 not v3) ... this restores the missing updates:

  * Fix the cmdlinepart *regression* that caused testing failures (!!)
    by restoring the original part labels in relevant cases.

  * Don't reference things that don't exist (!)
	- An opcode that doesn't even exist for DataFlash
	- The part is "at45db642" not "at45db641"
	- ID zero in this JEDEC table

  * Make the JEDEC probe routine report and handle errors better:
	- If the SPI calls fail, return the error codes.
	- Don't depend on ordering of table entries.
	- Unrecognized ids are different from parts that have no ID.
          We won't actually know how to handle them correctly; display
	  the ID and ignore the chip.

  * Move the original block comment about the "legacy" chip ID scheme
    back next to the code to which it applies ... not next to the new
    JEDEC query code, which uses an entirely different strategy.

  * Don't print a guessed erasesize; /proc/mtd has the real value.

And add a few more comments.

0bc88c59cc [MTD] block2mtd: logging typo fixes
Address a number of small issues mainly regarding the output made by this
driver to dmesg:

- Some of the blkmtd's had not been changed to block2mtd which caused
  display problem

- the parse_err() macro was displaying "block2mtd: " twice

2875fb65f8 mtd: memory corruption in block2mtd.c
The block2mtd driver (drivers/mtd/devices/block2mtd.c) will kfree an on-stack
pointer when handling an invalid argument line (e.g.
block2mtd=/dev/loop0,xxx).

The kfree was added some time ago when "name" was dynamically allocated.

2b54aaef7a Claim maintainership for block2mtd and update email addresses
I have been prime author and maintainer of block2mtd from day one, but
neither MAINTAINERS nor the module source makes this fact clear.  And while
I'm at it, update my email addresses tree-wide, as the old address
currently bounces and change my name to "joern" as unicode will likely
continue to cause trouble until the end of this century.
