[dpdk-dev] [PATCH 2/2] vhost_xen: fix compilation on 32 bits

[Pablo de Lara <pablo.de.lara.guarch@intel.com>]

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")                                                              ^
