[GIT PULL] (swiotlb) stable/for-linus-4.9 for 4.10 merge window

[Konrad Rzeszutek Wilk]

Hey Linus!

Please git pull the following branch:

 git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb.git stable/for-linus-4.9

which has:
 - Minor fixes (rate limiting), remove certain functions.
 - Support for DMA_ATTR_SKIP_CPU_SYNC which is an optimization in the
   DMA API

That is it!

Regarding the name of the branch - I was initially thinking to send it
to you for rc4 (in 4.9 time frame) but figured it may be just simpler
to do it during merge window.
