acc8dadc0b [PATCH] Remove blkmtd
Remove the blkmtd driver.

- An alternative exists (block2mtd) that hasn't had  bug report for > 1 year.

- Most embedded people tend to use ancient kernels with custom patches from
  mtd cvs and elsewhere, so the 1 year warning period neither helps nor hurts
  them too much.

- It's in the way of klibc.  The problems caused by pulling blkmtd support
  are fairly low, while the problems caused by delaying klibc can be fairly
  substantial.  At best, this would be a severe burden on hpa's time.

4d55146598 [PATCH] mtd: fix broken name_to_dev_t() declaration
drivers/mtd/devices/blkmtd.c uses a local declaration of name_to_dev_t()
which is inconsistant with the real one.  the following patch fixes this by
removing the local declaration and including mount.h instead

this patch was originally done by Micah Anderson.

3cb4f09fc2 [PATCH] mtd_dataflash, fix block vs page erase
Fix a bug in the block-erase optimization for Dataflash; it was using block
erase even for smaller segments that need page erase.

That wouldn't matter for JFFS2, which never erases less than one block
(sometimes several blocks), but for other callers it might.

8275c642cc [PATCH] spi: use linked lists rather than an array
This makes the SPI core and its users access transfers in the SPI message
structure as linked list not as an array, as discussed on LKML.

From: David Brownell <dbrownell@users.sourceforge.net>

  Updates including doc, bugfixes to the list code, add
  spi_message_add_tail().  Plus, initialize things _before_ grabbing the
  locks in some cases (in case it grows more expensive).  This also merges
  some bitbang updates of mine that didn't yet make it into the mm tree.

2f9f762879 [PATCH] spi: M25 series SPI flash
This was originally a driver for the ST M25P80 SPI flash.  It's been
updated slightly to handle other M25P series chips.

For many of these chips, the specific type could be probed, but for now
this just requires static setup with flash_platform_data that lists the
chip type (size, format) and any default partitioning to use.

1d6432fe10 [PATCH] spi: mtd dataflash driver
This is a conversion of the AT91rm9200 DataFlash MTD driver to use the
lightweight SPI framework, and no longer be AT91-specific.  It compiles
down to less than 3KBytes on ARM.

The driver allows board-specific init code to provide platform_data with
the relevant MTD partitioning information, and hotplugs.

This version has been lightly tested.  Its parent at91_dataflash driver has
been pretty well banged on, although kernel.org JFFS2 dataflash support was
acting broken the last time I tried it.

733482e445 [PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reason
This patch removes almost all inclusions of linux/version.h.  The 3
#defines are unused in most of the touched files.

A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
unfortunatly in linux/version.h.

There are also lots of #ifdef for long obsolete kernels, this was not
touched.  In a few places, the linux/version.h include was move to where
the LINUX_VERSION_CODE was used.

quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'`

search pattern:
/UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h

4e57b68178 [PATCH] fix missing includes
I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.

cleanup of calls to kfree for all of drivers/ - the kfree bit is partial in
that I only did the files that also had vfree calls in them.  The patch

[vk]free, and a some tiny whitespace corrections also crept in.

3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
