Merge tag 'for-linus-3.4' of git://git.infradead.org/mtd-2.6

Pull MTD changes from David Woodhouse:
 - Artem's cleanup of the MTD API continues apace.
 - Fixes and improvements for ST FSMC and SuperH FLCTL NAND, amongst
   others.
 - More work on DiskOnChip G3, new driver for DiskOnChip G4.
 - Clean up debug/warning printks in JFFS2 to use pr_<level>.

Fix up various trivial conflicts, largely due to changes in calling
conventions for things like dmaengine_prep_slave_sg() (new inline
wrapper to hide new parameter, clashing with rewrite of previously last
parameter that used to be an 'append' flag, and is now a bitmap of
'unsigned long flags').

(Also some header file fallout - like so many merges this merge window -
and silly conflicts with sparse fixes)
