I am trying to add a hypercall to replace the iret instruction in xenolinux, so that everytime control comes to xen when guest OS executes 'iret'.
I found that there already exists a hypercall HYPERVISOR_iret in xen.
  What is the exact functionality of HYPERVISOR_iret? In which cases is it called by the guest OS?

Please help.
