      mtd: blktrans: Hotplug fixes · 048d8719
      Maxim Levitsky authored
      * Add locking where it was missing.
      * Don't do a get_mtd_device in blktrans_open because it would lead to a
        deadlock; instead do that in add_mtd_blktrans_dev.
      * Only free the mtd_blktrans_dev structure when the last user exits.
      * Flush request queue on device removal.
      * Track users, and call tr->release in del_mtd_blktrans_dev
        Due to that ->open and release aren't called more that once.
      Now it is safe to call del_mtd_blktrans_dev while the device is still in use.

      mtd: Use BLOCK_NIL consistently in NFTL/INFTL · 70ec3bb8
      Julia Lawall authored
      Use BLOCK_NIL consistently rather than sometimes 0xffff and sometimes
      The semantic patch that finds this issue is below
      (http://www.emn.fr/x-info/coccinelle/).  On the other hand, the changes
      were made by hand, in part because drivers/mtd/inftlcore.c contains dead
      code that causes spatch to ignore a relevant function.  Specifically, the
      function INFTL_findwriteunit contains a do-while loop, but always takes a
      return that leaves the loop on the first iteration.

      [MTD] update internal API to support 64-bit device size · 69423d99
      Adrian Hunter authored
      MTD internal API presently uses 32-bit values to represent
      device size.  This patch updates them to 64-bits but leaves
      the external API unchanged.  Extending the external API
      is a separate issue for several reasons.  First, no one
      needs it at the moment.  Secondly, whether the implementation
      is done with IOCTLs, sysfs or both is still debated.  Thirdly
      external API changes require the internal API to be accepted
      Note that although the MTD API will be able to support 64-bit
      device sizes, existing drivers do not and are not required
      to do so, although NAND base has been updated.
      In general, changing from 32-bit to 64-bit values cause little
      or no changes to the majority of the code with the following
          	- printk message formats
          	- division and modulus of 64-bit values
          	- NAND base support
      	- 32-bit local variables used by mtdpart and mtdconcat
      	- naughtily assuming one structure maps to another
      	in MEMERASE ioctl

      PCI: Cleanup the includes of <linux/pci.h> · 6473d160
      Jean Delvare authored
      I noticed that many source files include <linux/pci.h> while they do
      not appear to need it. Here is an attempt to clean it all up.
      In order to find all possibly affected files, I searched for all
      files including <linux/pci.h> but without any other occurence of "pci"
      or "PCI". I removed the include statement from all of these, then I
      compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
      false positives manually.
      My tests covered 66% of the affected files, so there could be false
      positives remaining. Untested files are:
      I would welcome test reports for these files. I am fine with removing
      the untested files from the patch if the general opinion is that these
      changes aren't safe. The tested part would still be nice to have.
      Note that this patch depends on another header fixup patch I submitted
      to LKML yesterday:
        [PATCH] scatterlist.h needs types.h

      [PATCH] remove many unneeded #includes of sched.h · cd354f1a
      Tim Schmielau authored
      After Al Viro (finally) succeeded in removing the sched.h #include in module.h
      recently, it makes sense again to remove other superfluous sched.h includes.
      There are quite a lot of files which include it but don't actually need
      anything defined in there.  Presumably these includes were once needed for
      macros that used to live in sched.h, but moved to other header files in the
      course of cleaning it up.
      To ease the pain, this time I did not fiddle with any header files and only
      removed #includes from .c-files, which tend to cause less trouble.
      Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
      arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
      allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
      configs in arch/arm/configs on arm.  I also checked that no new warnings were
      introduced by the patch (actually, some warnings are removed that were emitted
      by unnecessarily included header files).

      [MTD] NAND Signal that a bitflip was corrected by ECC · 9a1fcdfd
      Thomas Gleixner authored
      Return -EUCLEAN on read when a bitflip was detected and corrected, so the
      clients can react and eventually copy the affected block to a spare one.
      Make all in kernel users aware of the change.

      [MTD] Rework the out of band handling completely · 8593fbc6
      Thomas Gleixner authored
      Hopefully the last iteration on this!
      The handling of out of band data on NAND was accompanied by tons of fruitless
      discussions and halfarsed patches to make it work for a particular
      problem. Sufficiently annoyed by I all those "I know it better" mails and the
      resonable amount of discarded "it solves my problem" patches, I finally decided
      to go for the big rework. After removing the _ecc variants of mtd read/write
      functions the solution to satisfy the various requirements was to refactor the
      read/write _oob functions in mtd.
      The major change is that read/write_oob now takes a pointer to an operation
      descriptor structure "struct mtd_oob_ops".instead of having a function with at
      least seven arguments.
      read/write_oob which should probably renamed to a more descriptive name, can do
      the following tasks:
      - read/write out of band data
      - read/write data content and out of band data
      - read/write raw data content and out of band data (ecc disabled)
      struct mtd_oob_ops has a mode field, which determines the oob handling mode.
      Aside of the MTD_OOB_RAW mode, which is intended to be especially for
      diagnostic purposes and some internal functions e.g. bad block table creation,
      the other two modes are for mtd clients:
      MTD_OOB_PLACE puts/gets the given oob data exactly to/from the place which is
      described by the ooboffs and ooblen fields of the mtd_oob_ops strcuture. It's
      up to the caller to make sure that the byte positions are not used by the ECC
      placement algorithms.
      MTD_OOB_AUTO puts/gets the given oob data automaticaly to/from the places in
      the out of band area which are described by the oobfree tuples in the ecclayout
      data structre which is associated to the devicee.
      The decision whether data plus oob or oob only handling is done depends on the
      setting of the datbuf member of the data structure. When datbuf == NULL then
      the internal read/write_oob functions are selected, otherwise the read/write
      data routines are invoked.
      Tested on a few platforms with all variants. Please be aware of possible
      regressions for your particular device / application scenario
      Disclaimer: Any whining will be ignored from those who just contributed "hot
      air blurb" and never sat down to tackle the underlying problem of the mess in
      the NAND driver grown over time and the big chunk of work to fix up the
      existing users. The problem was not the holiness of the existing MTD
      interfaces. The problems was the lack of time to go for the big overhaul. It's
      easy to add more mess to the existing one, but it takes alot of effort to go
      for a real solution.
      Improvements and bugfixes are welcome!

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      Let it rip!
