Subject: linux-next: manual merge of the nand tree with the asm-generic tree

Hi Boris,

Today's linux-next merge of the nand tree got a conflict in:

  drivers/mtd/nand/Kconfig
  (mostly moved to drivers/mtd/nand/raw/Kconfig)
  drivers/mtd/nand/Makefile
  (mostly moved to drivers/mtd/nand/raw/Makefile)
  drivers/mtd/nand/bf5xx_nand.c
  (renamed to drivers/mtd/nand/raw/bf5xx_nand.c)
  arch/cris/arch-v32/drivers/mach-a3/nandflash.c
  arch/cris/arch-v32/drivers/mach-fs/nandflash.c

between commits:

  2180873c59e1 ("mtd: nand: remove bf5xx_nand driver")
  77b0b77f7812 ("CRIS: Drop support for the CRIS port")

from the asm-generic tree and commits:

  93db446a424c ("mtd: nand: move raw NAND related code to the raw/ subdir")
  187c54488ead ("mtd: nand: State when references to other drivers are no longer valid")

from the nand tree.

I fixed it up:

    I removed:
	drivers/mtd/nand/raw/bf5xx_nand.c
	arch/cris/arch-v32/drivers/mach-a3/nandflash.c
	arch/cris/arch-v32/drivers/mach-fs/nandflash.c
    added the following merge fix patch

and can carry the fix as necessary. This is now fixed as far as linux-next
is concerned, but any non trivial conflicts should be mentioned to your
upstream maintainer when your tree is submitted for merging.  You may
also want to consider cooperating with the maintainer of the conflicting
tree to minimise any particularly complex conflicts.
