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.

f63af11ddb [MTD] [NAND] remove __PPC__ hardcoded address from DiskOnChip drivers
Such a hardcoded address can cause a checkstop or machine check if
the driver is in the kernel but the address is not acknowledged.

Both drivers allow an address to be specified as either a module
parameter or config option.   Any future powerpc board should either
use one of these methods or find the address in the device tree.

fa0a8c71f3 [MTD] m25p80 handles more chips, uses JEDEC ids and small eraseblocks
Update chip ID tables in m25p80 to handle more SPI flash chips, matching
datasheets.  All of these can use the same core operations and are newer
chips that support the JEDEC "read id" instruction:

 - Atmel AT25 and AT26 (seven chips)
 - Spansion S25SL (five chips)
 - SST 25VF (four chips)
 - ST M25, M45 (five more chips)
 - Winbond W25X series (seven chips)

That JEDEC instruction is now used, either to support a sanity check on the
platform data holding board configuration data, or to determine chip type
when it's not included in platform data.  In fact, boards that don't need a
standard partition table may not need that platform data any more.

For chips that support 4KiB erase units, use that smaller block size instead
of the larger size (usually 64KiB); it's less wasteful.  (Tested on W25X80.)

632155e659 potential parse error in ifdef
I have made a tool to parse the kernel that does not pre-process the
source.  That means that my parser tries to parse all the code, including
code in the #else branch or code that is not often compiled because the
driver is not very used (or not used at all).  So, my parser sometimes
reports parse error not originally detected by gcc.  Here is my (first)

6fe6900e1e mm: make read_cache_page synchronous
Ensure pages are uptodate after returning from read_cache_page, which allows
us to cut out most of the filesystem-internal PageUptodate calls.

I didn't have a great look down the call chains, but this appears to fixes 7
possible use-before uptodate in hfs, 2 in hfsplus, 1 in jfs, a few in
ecryptfs, 1 in jffs2, and a possible cleared data overwritten with readpage in
block2mtd.  All depending on whether the filler is async and/or can return
with a !uptodate page.

6473d160b4 PCI: Cleanup the includes of <linux/pci.h>
I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.

In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.

My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.

Note that this patch depends on another header fixup patch I submitted
to LKML yesterday:
  [PATCH] scatterlist.h needs types.h

340ea370c2 [MTD] Driver for AT26Fxxx dataflash devices
Add support for AT26Fxxx dataflash devices. These devices have a quite different
commandset than the AT45xxx chips, which are handled by at91_dataflash.c, so a
combined driver turned out to be more ugly than useful.

Tested only on AT26F004.

21d31f1f7c [PATCH] [MTD] block2mtd: remove readahead code
Over the years there was a slow trickle of complaints against the readahead
code.  Most of them concerned performance, Peter Zijlstra stumbled over it
when working unrelated changes and I believe there was an actual bug report.
Oh, Andrew Morton also complained about duplicating code from mm/readahead.c.

It is just not worth it.  On flash media like usb sticks, readahead will
make things go slow - very slow.  On spinning disks, readahead may be a
win, but this is definitely not the place to add it.

cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).
