Merge git://git.infradead.org/mtd-2.6
* git://git.infradead.org/mtd-2.6:
[MTD][NOR] Add physical address to point() method
[JFFS2] Track parent inode for directories (for NFS export)
[JFFS2] Invert last argument of jffs2_gc_fetch_inode(), make it boolean.
[JFFS2] Quiet lockdep false positive.
[JFFS2] Clean up jffs2_alloc_inode() and jffs2_i_init_once()
[MTD] Delete long-unused jedec.h header file.
[MTD] [NAND] at91_nand: use at91_nand_{en,dis}able consistently.
