Re: [Xen-devel] [RFC 0/2] XEN SWIOTLB for ARM dma operations extension

Dear Konrad,

Please see my comments below:

I'm not really sure what do you mean.
The patch I refer was done for LK 3.4 if I remember, it is not 
applicable to 4.6 I'm currently working with.
Moreover xen-swiotlb infrastructure changed significantly so the patch 
is completely reworked. The only
common code is that mmap is defined in ARM specific xen_swiotlb_dma_ops.
I just refer to it and left author and signed-of-s as a respect to the 
work done few years ago.

I've encapsulated all the code changes in an arch/arm/xen/mm.c so I 
don't think your doubts and Stephano's comment
about x86 build impact is relevant here.
