From: Arnd Bergmann In a few rare configurations with extra warnings eanbled, the new drm_pagemap_migrate_populate_ram_pfn() calls vma_alloc_folio_noprof() but that does not use all the arguments, leading to a harmless warning: drivers/gpu/drm/drm_pagemap.c: In function 'drm_pagemap_migrate_populate_ram_pfn': drivers/gpu/drm/drm_pagemap.c:701:63: error: parameter 'addr' set but not used [-Werror=unused-but-set-parameter=] 701 | unsigned long addr) | ~~~~~~~~~~~~~~^~~~ Replace the macro with an inline function so the compiler can see how the argument would be used, but is still able to optimize out the assignments.
