* git://git.infradead.org/mtd-2.6: (199 commits) [MTD] NAND: Fix breakage all over the place [PATCH] NAND: fix remaining OOB length calculation [MTD] NAND Fixup NDFC merge brokeness [MTD NAND] S3C2410 driver cleanup [MTD NAND] s3c24x0 board: Fix clock handling, ensure proper initialisation. [JFFS2] Check CRC32 on dirent and data nodes each time they're read [JFFS2] When retiring nextblock, allocate a node_ref for the wasted space [JFFS2] Mark XATTR support as experimental, for now [JFFS2] Don't trust node headers before the CRC is checked. [MTD] Restore MTD_ROM and MTD_RAM types [MTD] assume mtd->writesize is 1 for NOR flashes [MTD NAND] Fix s3c2410 NAND driver so it at least _looks_ like it compiles [MTD] Prepare physmap for 64-bit-resources [JFFS2] Fix more breakage caused by janitorial meddling. [JFFS2] Remove stray __exit from jffs2_compressors_exit() [MTD] Allow alternate JFFS2 mount variant for root filesystem. [MTD] Disconnect struct mtd_info from ABI [MTD] replace MTD_RAM with MTD_GENERIC_TYPE [MTD] replace MTD_ROM with MTD_GENERIC_TYPE [MTD] remove a forgotten MTD_XIP ...
