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.

2/* JEDEC Flash Interface.
3 * This is an older type of interface for self programming flash. It is
4 * commonly use in older AMD chips and is obsolete compared with CFI.
5 * It is called JEDEC because the JEDEC association distributes the ID codes
6 * for the chips.
7 *
8 * See the AMD flash databook for information on how to operate the interface.
