[PATCH 1/2] xen/events: Fix xen_set_upcall_vector stub
Jason Andryuk <[email protected]>
| Newsgroups | org.xenproject.lists.xen-devel,org.kernel.vger.linux-kernel |
|---|---|
| Message-ID | <[email protected]> |
Building the xen_set_upcall_vector stub fails with
error: control reaches end of non-void function.
Return -EINVAL, which matches the hypercall's return for a non-HVM
domain.
This is needed to allow disabling CONFIG_XEN_PVHVM.
Fixes: b1c3497e604d ("x86/xen: Add support for HVMOP_set_evtchn_upcall_vector")
