  mtd: don't WARN about overloaded users of mtd->reboot_notifier.notifier_call (2015-11-06 09:33:15 -0800)

----------------------------------------------------------------
MTD updates for 4.4-rc1:

 Core

  * WARN (in some cases) when a struct mtd_info is registered multiple times;
    in the past this was "supported", but it's still error prone for future
    development. There's only one ugly case of this left in the tree (that
    we're aware of) and the owners are aware of the problems there.

  * fix potential deadlock in the blkdev removal path
    NOTE: the (potential) deadlock was introduced in a for-stable patch. This
    one is also marked for -stable.

  * ioctl(BLKPG) compat_ioctl support; resolves issues with 32-bit user space
    vs. 64-bit kernel space

  * Set MTD parent device correctly throughout the tree, so the tree structure
    appears correctly in sysfs; many drivers were missing this (soft)
    requirement

  * Move device tree partitions (ofpart) into a dedicated 'partitions' subnode;
    this helps to disambiguate whether a node is a partition or some other
    auxiliary data

  * Improve error handling for partitioning failures

 NAND

  * General: Increase timeout period, for corner-case systems with
    less-than-accurate jiffies

  * Fix OF-based autoloading of several NAND drivers when built as modules

  * pxa3xx_nand:
    - Rework timing configuration to be more dynamic
    - Refactor PM support

  * brcmnand: prepare for NorthStar 2 support (ARM64, 16-bit NAND chips)

  * sunxi_nand: refactoring and a few bug fixes

  * vf610: new NAND driver

  * FSMC: add SW BCH support; support common NAND DT bindings

  * lpc32xx_slc: refactor and improve timing calculations logic

  * denali: support for rev 5.1

 SPI NOR

  * Layering improvements

  * Added Winbond lock/unlock support

  * Added mtd_is_locked() (i.e., ioctl(MEMISLOCKED)) support

  * Increase full-chip-erase timeout linearly with flash size

  * fsl-quadspi: fix compile for non-ARM architectures

  * New flash support
