I was going to also commit patch #6, but it looks like an ack is missing from Paul. I still haven't reviewed the rest of the patches. Cheers,
From: Oleksandr Andrushchenko <oleksandr_andrushchenko@epam.com> Hi, all! This is an assorted series of patches which aim is to make some further basis for PCI passthrough on Arm support. The series continues the work published earlier by Arm [1] and adds new helpers and clears the way for vPCI changes which will follow. RFC is at [2], [3]. Design presentation can be found at [4]. I have removed patch [PATCH v6 5/7] xen/arm: do not map IRQs and memory for disabled devices as it seems that this needs more time for decision on how to achive that. I have also added a new patch [PATCH v7 4/7] xen/arm: account IO handler for emulated PCI host bridge with a tiny latent bug fix.
