This is a forward port of the SD/MMC driver from the latest LSP,
melded into linux-2.6.23-git. I've tried to keep the style updates
that were merged recently. I've fixed the exit code (in
davinci_mmcsd_exit) to release clocks, and some failure paths in
davinci_mmcsd_init.

The driver as is performs ~6MB/s reads and ~1MB/s writes with a
block size of 512k (i.e. still needs help!). This patch just makes
the driver usable again.

Prevent OTG peripheral trying to change to b_wait_acon if after
file storage CBW stall followed by SUSPEND from host. We switch
back to b_peripheral if RESET in b_wait_acon mode.

Also fix compile warning for missing default case.

And don't try to set b_wait_acon mode unless CONFIG_USB_OTG.

Clean up OMAP2 Kconfig.  Again.

 - 34xx shouldn't go in the middle of the 24xx stuff, it
   goofs the dependency tree displayed by e.g. kconfig.
   In particular, not in the middle of the H4-specific
   options.

 - Make the 2420 boards depend on OMAP2420, and 2430 boards
   on OMAP2430 ... a 2420-only kernel shouldn't show 2430
   boards, and vice versa.

This patch fixes a wrong ifdef in the board setup code, leading to the GPIO
pin not being pulled high, and thus the USB switch not being powered at all.

This finishes the rename of CONFIG_USB_OHCI to CONFIG_USB_OHCI_HCD, which
started in 2005 (before 2.6.12-rc2), then probably because things were
working anyway for most people got forgotten.

[Ralf: Paolo's original patch didn't fix the module case, Florian's patch
only fixed MTX1 etc. so this is a combined patch plus some cleanups.]

When building a custom keymap, after setting GENERATE_KEYMAP := 1 in
drivers/char/Makefile, the kernel build fails like this:

  make[2]: *** No rule to make target `drivers/char/%.map', needed by `drivers/char/defkeymap.c'.  Stop.
  make[1]: *** [drivers/char] Error 2

This was caused by commit af8b1287, which
deleted a necessary colon from the Makefile rule that generates the keymap,
since that rule contains both a target and a target-pattern.  The following

All the current page_mkwrite() implementations also set the page dirty. Which
results in the set_page_dirty_balance() call to _not_ call balance, because the
page is already found dirty.

This allows us to dirty a _lot_ of pages without ever hitting
balance_dirty_pages().  Not good (tm).

Force a balance call if ->page_mkwrite() was successful.
