I applied all 14 patches on top of current v3.2-rc4
and regression-tested the whole shebang on RealView PB1176
and U300.

- Mounted /dev/mmcblk0p1
- Copy a kernel-sized uImage file from the card to ramdisk
- Copy the file back to the card from ramdisk
- Unmount
- Mount
- Compare the two files with diff (identical)
- Delete copy
- Unmount
- dd if=/dev/mmcblk0 of=/dev/null

(If any of you wants any more specific tests, tell me.)

Both platforms still work like a charm with these patches.
PB1176 is as slow on MMC as it always has been but dd:ed
the entire card without errors.

I have the branch here:
git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson.git mmci

Ulf you can add my Tested-by: Linus Walleij <linus.walleij at linaro.org>
for these patches.

Russell if you want a pull request for a subset of the patches I can
arrange that, just tell me.
