[Xen-devel] [PATCH-4.5 0/4] remove maintenance interrupts

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

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.

Please test!!


Stefano Stabellini (4):
      xen/arm: remove unused virtual parameter from vgic_vcpu_inject_irq
      xen/arm: support HW interrupts in gic_set_lr
      xen/arm: do not request maintenance_interrupts
      xen/arm: set GICH_HCR_NPIE if all the LRs are in use
