Most of these have been purged years ago.  This one silently lived
on until commit 69349c2d

    "kconfig: fix IS_ENABLED to not require all options to be defined"

In the above, we use some macro trickery to create a conditional that
is valid in CPP and in C usage.  However that trickery doesn't sit
well if you have the legacy "-traditional" flag enabled.  You'll get:

  AS      arch/cris/arch-v10/lib/checksum.o
In file included from <command-line>:4:0:
include/linux/kconfig.h:23:0: error: syntax error in macro parameter list
make[2]: *** [arch/cris/arch-v10/lib/checksum.o] Error 1

Everything builds fine w/o "-traditional" so simply drop it from this
location as well.

Pull dma-buf prime support from Dave Airlie:
 "This isn't a majorly urgent thing to have, but we'd like to set the
  stage for working on dma-buf support in the drm drivers for the next
  merge window, so I'd like to push in the initial submission now so
  people have something that we can build on top of.  The code just
  introduces the user interface and internal helper functions for
  drivers to use.

  We have driver support under development for i915, nouveau, udl on x86
  and exynos, omapdrm on arm, which we would be aiming for the next
  merge window."

Commit bf4289cb ("ATMEL: fix nand ecc support") indicated that it
wanted to "Move platform data to a common header

re-include protectors with:

    #ifndef __ATMEL_NAND_H__

However, the file that was added was simply called atmel.h

Builds of the MIPS platform ip32_defconfig fails as of commit
0195c002 ("Merge tag 'split-asm_system_h ...") because MIPS xchg()
macro uses BUILD_BUG_ON and it was moved in commit b81947c6
("Disintegrate asm/system.h for MIPS").

The root cause is that the system.h split wasn't tested on a baseline
with commit 6c03438e ("kernel.h: doesn't explicitly use bug.h, so
don't include it.")

Since this file uses BUG code in several other places besides the xchg
call, simply make the inclusion explicit.
