On i386, when builtin (not a loadable module), the winbond-840 driver inspects boot_cpu_data to see what CPU family it is running on, and then acts on that data. The "family" struct member (x86) does not exist when running on UML, so prevent that test and do the default action. Prevents this build error on UML + i386: ../drivers/net/ethernet/dec/tulip/winbond-840.c: In function ‘init_registers’: ../drivers/net/ethernet/dec/tulip/winbond-840.c:882:19: error: ‘struct cpuinfo_um’ has no member named ‘x86’ if (boot_cpu_data.x86 <= 4) { Fixes: 68f5d3f3b654 ("um: add PCI over virtio emulation driver") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: linux-um@lists.infradead.org Cc: Jeff Dike <jdike@addtoit.com> Cc: Richard Weinberger <richard@nod.at> Cc: Anton Ivanov <anton.ivanov@cambridgegreys.com> Cc: "David S.
