Copy these macros from ia64/include/asm/agp.h to avoid the "empty-body" in 'if' statment warning.
drivers/char/agp/generic.c: In function 'agp_generic_destroy_page': ../drivers/char/agp/generic.c:1265:42: warning: suggest braces around empty body in an 'if' statement [-Wempty-body] 1265 | unmap_page_from_agp(page);
