  [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.
