There are several functions involved for performing the functionality
of evtchn_do_upcall():
- __xen_evtchn_do_upcall() doing the real work
- xen_hvm_evtchn_do_upcall() just being a wrapper for
__xen_evtchn_do_upcall(), exposed for external callers
- xen_evtchn_do_upcall() calling __xen_evtchn_do_upcall(), too, but
without any user
Simplify this maze by:
- removing the unused xen_evtchn_do_upcall()
- removing xen_hvm_evtchn_do_upcall() as the only left caller of
__xen_evtchn_do_upcall(), while renaming __xen_evtchn_do_upcall() to
xen_evtchn_do_upcall()
