Compilation fails on 32 bits on Vhost_xen sample app, due to wrong casting:
examples/vhost_xen/vhost_monitor.c: In function ?new_device?:
examples/vhost_xen/vhost_monitor.c:288:62: error: cast from pointer to integer
of different size [-Werror=pointer-to-int-cast]
gpa = new_ll_dev->dev.mem->regions[i].guest_phys_address =
(uint64_t)guest->mempool[i].gva;
Fixes: 47bd46112b71 ("xen: import xenvirt pmd and vhost_xen")
