- Enable modular build of the new device model tests, - Enable modular build of the glob self-test on configs that didn't have it yet (visible since commit b67abaad ("kunit: Allow kunit test modules to use test filtering")), - Replace CONFIG_FB=y by CONFIG_FRAMEBUFFER_CONSOLE=y on the virt platform (the former is no longer needed since commit 55bffc81 ("fbdev: Split frame buffer support in FB and FB_CORE symbols")), the latter is no longer auto-enabled since commit a5ae331e ("drm: Drop select FRAMEBUFFER_CONSOLE for DRM_FBDEV_EMULATION")).

Upstream Linux never had a "README.legal" file, but it was present in early source releases of Linux/m68k. It contained a simple copyright notice and a link to a version of the "COPYING" file that predated the addition of the "only valid GPL version is v2" clause. Get rid of the references to non-existent files by replacing the boilerplate with SPDX license identifiers. Signed-off-by:
