| |
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
