[PATCH 6.0 0735/1073] fbdev: uvesafb: dont build on UML

STALE1373d

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Date: 2022-12-28 16:27:48
Also in: dri-devel, linux-patches, linux-um, stable
Subsystem: framebuffer layer, the rest · Maintainers: Helge Deller, Linus Torvalds

From: Randy Dunlap <rdunlap@infradead.org>

[ Upstream commit 35b4f4d4a725cf8f8c10649163cd12aed509b953 ]

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) {
