Hi Wei Liu, Julien,

Hi Stefano,


this series is a bug fix. I think it should go in Xen 4.7, do you agree?

Some changes in this series impact the emulation of PSCI for guest (see target_affinity_mask in vpsci.c). Looking at the code again, they should be low risk as Xen only supports AFF0 and AFF1 for the vmpidr.

I think it should be fine to go in Xen 4.7, however osstest will not be able to catch any possible regression due to lack of ARM64 hardware in the colo.

I just tested on Juno and I did not find any regression. I think Wei tested on Overdrive (?). Edgar, can you give it a go on the xilinx board?

Regards,
