Subject[PATCH v3 00/11] fix swiotlb-xen for RPi4
Hi all,

This series is a collection of fixes to get Linux running on the RPi4 as
dom0. Conceptually there are only two significant changes:

- make sure not to call virt_to_page on vmalloc virt addresses (patch
#1)
- use phys_to_dma and dma_to_phys to translate phys to/from dma
addresses (all other patches)


I addressed all comments by Christoph to v2 of the series except from
the one about merging the precursor "add struct device *" patches. I can
always merge them together at any time as needed.


Boris gave his Reviewed-by to the whole series v2. I added his
Reviewed-by to all patches, including the ones with small cosmetic
fixes, except for patch #8 #9 #10 because they are either new or changed
significantly in this version of the series.

I retained Roman and Corey's Tested-by.


Cheers,

Stefano
