We should probably take into account what happens with Tamas' "vm_event:
consolidate hvm_event_fill_regs and p2m_vm_event_fill_regs" patch here.
That patch already affects hvm_event_fill_regs().

Well it seems one of us will have to rebase depending which patch gets accepted & merged first. The conflict is minimal so it's not a major issue. If my patch gets merged first then just have to introduce the empty function in the ARM header with the new name.

Tamas

Okay then, for me it's fine either way.

Corneliu.
