Applied, thank you both!  These both are ready for the upcoming merge
window.

While I am at it, here is the current scorecard:

e9ff68680cd4 tools/memory-model: Add litmus test for full multicopy atomicity
c21fcc6594f1 tools/memory-model: Fix ISA2+pooncelock+pooncelock+pombonce name
aa838e0b70e1 MAINTAINERS: Add Daniel Lustig as an LKMM reviewer
3cb0d7701c4c locking/memory-barriers.txt/kokr: Update Korean translation to fix broken DMA vs. MMIO ordering example
0bde941f3629 tools/memory-model: Remove ACCESS_ONCE() from recipes
80b7b05c3aa0 tools/memory-model: Remove ACCESS_ONCE() from model

	The above patches are ready for the upcoming merge window because
	each has at least one Acked-by or Reviewed-by.

6098ce88bc4d tools/memory-model: Make scripts executable
5bb22d0126f9 tools/memory-model: Rename litmus tests to comply to norm7
1bc179880fba docs: atomic_ops: Describe atomic_set as a write operation

	The above patches need at least one additional Acked-by
	or Reviewed-by.  If any of you gets a chance, please do
	look them over.

51b0a8985c5a EXP tools/memory-model: Add litmus-test naming scheme

	This patch needs me to get Will Deacon's feedback applied.  :-/

06e99a0d9662 EXP tools/memory-model: Add .cfg and .cat files for s390

	This is a placeholder, and probably won't ever go upstream
	into the Linux kernel.  (Maybe someday into herd where the
	other architecture-specific .cat files live.)

							Thanx, Paul
