Re: [Xen-devel] [PATCH-4.5 v2 0/10] remove maintenance interrupts

Hi Stefano,

Hi all,
this patch series removes any needs for maintenance interrupts for both
hardware and software interrupts in Xen.
It achieves the goal by using the GICH_LR_HW bit for hardware interrupts
and by checking the status of the GICH_LR registers on return to guest,
clearing the registers that are invalid and handling the lifecycle of
the corresponding interrupts in Xen data structures.

To keep track here, I have tried the patch series on top of the latest Xen. Booting Xen and Dom0 is slower with this patch series.
