      of: mtd: prepare helper reading NAND ECC algo from DT · dd2dcc00
      Rafał Miłecki authored
      NAND subsystem is being slightly reworked to store ECC details in
      separated fields. In future we'll want to add support for more DT
      properties as specifying every possible setup with a single
      "nand-ecc-mode" is a pretty bad idea.
      To allow this let's add a helper that will support something like
      "nand-ecc-algo" in future. Right now we use it for keeping backward
      compatibility.

      mtd: nand: add new enum for storing ECC algorithm · b0fcd8ab
      Rafał Miłecki authored
      Our nand_ecc_modes_t is already a bit abused by value NAND_ECC_SOFT_BCH.
      This enum should store ECC mode only and putting algorithm details there
      is a bad idea. It would result in too many values impossible to support
      in a sane way.
      
      To solve this problem let's add a new enum. We'll have to modify all
      drivers to set it properly but once it's done it'll be possible to drop
      NAND_ECC_SOFT_BCH. That will result in a cleaner design and more
      possibilities like setting ECC algorithm for hardware ECC mode.

      Pull NAND/GPMC updates from Roger Quadros:
       "We do a couple of things in this series which result in cleaner device
        tree implementation, faster perfomance and multi-platform support. As
        an added bonus we get to use the GPMC_WAIT pins as GPI/Interrupts.
      
        - Establish a custom interface between NAND and GPMC driver. This is
          needed because all of the NAND registers sit in the GPMC register
          space.
      
        - Clean up device tree support so that omap-gpmc IP and the omap2 NAND
          driver can be used on non-OMAP platforms. e.g. Keystone.
      
        - Implement GPIOCHIP for the GPMC WAITPINS. SoCs can contain 2 to 4 of
          these and most of them would be unused otherwise. It also allows a
          cleaner implementation of NAND Ready pin status for the NAND driver.
      
        - Implement GPMC IRQ domain to proivde the 2 NAND events and GPMC
          WAITPIN edge interrupts.
      
        - Implement GPIOlib based NAND ready pin checking for OMAP NAND driver.
          On dra7-evm, Read speed increases from 13768 KiB/ to 17246 KiB/s.
          Write speed was unchanged at 7123 KiB/s."

      Pull orangefs filesystem from Mike Marshall.
      
      This finally merges the long-pending orangefs filesystem, which has been
      much cleaned up with input from Al Viro over the last six months.  From
      the documentation file:
      
       "OrangeFS is an LGPL userspace scale-out parallel storage system.  It
        is ideal for large storage problems faced by HPC, BigData, Streaming
        Video, Genomics, Bioinformatics.
      
        Orangefs, originally called PVFS, was first developed in 1993 by Walt
        Ligon and Eric Blumer as a parallel file system for Parallel Virtual
        Machine (PVM) as part of a NASA grant to study the I/O patterns of
        parallel programs.
      
        Orangefs features include:
      
          - Distributes file data among multiple file servers
          - Supports simultaneous access by multiple clients
          - Stores file data and metadata on servers using local file system
            and access methods
          - Userspace implementation is easy to install and maintain
          - Direct MPI support
          - Stateless"
      
      see Documentation/filesystems/orangefs.txt for more in-depth details.

      f2fs/crypto: fix xts_tweak initialization · 02fc59a0
      Linus Torvalds authored
      Commit 0b81d077 ("fs crypto: move per-file encryption from f2fs
      tree to fs/crypto") moved the f2fs crypto files to fs/crypto/ and
      renamed the symbol prefixes from "f2fs_" to "fscrypt_" (and from "F2FS_"
      to just "FS" for preprocessor symbols).
      
      Because of the symbol renaming, it's a bit hard to see it as a file
      move: use
      
          git show -M30 0b81d077
      
      to lower the rename detection to just 30% similarity and make git show
      the files as renamed (the header file won't be shown as a rename even
      then - since all it contains is symbol definitions, it looks almost
      completely different).
      
      Even with the renames showing as renames, the diffs are not all that
      easy to read, since so much is just the renames.  But Eric Biggers
      noticed that it's not just all renames: the initialization of the
      xts_tweak had been broken too, using the inode number rather than the
      page offset.
      
      That's not right - it makes the xfs_tweak the same for all pages of each
      inode.  It _might_ make sense to make the xfs_tweak contain both the
      offset _and_ the inode number, but not just the inode number.
