  Pull asm-generic updates from Arnd Bergmann:
  "There are only three patches this time, most other changes to files in
  include/asm-generic tend to go through the tree of whoever depends on
  the change.

  Two patches are cleanups for stuff that is no longer needed, the main
  change is to adapt the generic version of BUG_ON() for CONFIG_BUG=n to
  make it behave consistently with BUG().

  This avoids undefined behavior along with a number of warnings about
  that undefined behavior in randconfig builds when we keep going on
  after hitting a BUG_ON()"

  * tag 'asm-generic-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic:
  asm-generic: remove old nonatomic-io wrapper files
  asm-generic: default BUG_ON(x) to if(x)BUG()
  asm-generic: page.h: Remove useless get_user_page and free_user_page

• a1cbaad75   asm-generic: remove old nonatomic-io wrapper files ... Browse Code »

  The two header files got moved to include/linux, and most
  users were already converted, this changes the remaining drivers
  and removes the files.

  There are already helper functions to do 64-bit I/O on 32-bit machines, thus we
  don't need to reinvent the wheel. In our case we can't use readq() / writeq()
  even on 64-bit kernel since there is a hardware limitation (OCP bus is a 32-bit
  bus).

• 667dfed98   dmaengine: add a driver for Intel integrated DMA 64-bit ... Browse Code »

  Intel integrated DMA (iDMA) 64-bit is a specific IP that is used as a part of
  LPSS devices such as HSUART or SPI. The iDMA IP is attached for private
  usage on each host controller independently.

  While it has similarities with Synopsys DesignWare DMA, the following
  distinctions doesn't allow to use the existing driver:
  - 64-bit mode with corresponding changes in Hardware Linked List data structure
  - many slight differences in the channel registers

  Moreover this driver is based on the DMA virtual channels framework that helps
  to make the driver cleaner and easy to understand.
