drm: Fix Linux/DragonFly PAGE_MASK confusion * Both Linux and the DragonFly kernel use a PAGE_MASK constant, which is unfortunately defined differently in each one * Define a LINUX_PAGE_MASK macro and use it when applicable in the drm code to fix this confusion * One or two drm/radeon bugs were possibly caught during the process * This commit based on a patch by tuxillo Spotted-by: tuxillo Fixes: https://bugs.dragonflybsd.org/issues/3171
