Subject: [PATCH 2/2] fbdev: uvesafb: don't build on UML
The uvesafb fbdev driver uses memory management information that is not
available on ARCH=um, so don't allow this driver to be built on UML.
Prevents these build errors:
../drivers/video/fbdev/uvesafb.c: In function ‘uvesafb_vbe_init’:
../drivers/video/fbdev/uvesafb.c:807:21: error: ‘__supported_pte_mask’ undeclared (first use in this function)
807 | if (__supported_pte_mask & _PAGE_NX) {
../drivers/video/fbdev/uvesafb.c:807:44: error: ‘_PAGE_NX’ undeclared (first use in this function)
807 | if (__supported_pte_mask & _PAGE_NX) {
Fixes: 68f5d3f3b654 ("um: add PCI over virtio emulation driver")
