A better list, searching for all attributes used anywhere in the kernel:

git grep -E '^\s*#define\s+(address_space|alias|aligned|always_inline|assume_aligned|bitwise|bnd_legacy|cold|common|const|constructor|context|deprecated|designated_init|destructor|error|externally_visible|flatten|force|format|format|gnu_inline|hot|hotpatch|indirect_branch|latent_entropy|long_call|malloc|may_alias|mode|model|naked|nocast|noclone|noderef|noinline|no_instrument_function|nonnull|no_randomize_layout|noreturn|no_sanitize_address|optimize|packed|pure|randomize_layout|regparm|require_context|safe|section|syscall_linkage|target|tls_model|unused|used|user|vector_size|visibility|warning|warn_unused_result|weak)(\(|\s|$)'

arch/mips/sgi-ip27/ip27-reset.c:#define noreturn while(1);
                 /* Silence gcc.  */
arch/parisc/boot/compressed/misc.c:#define malloc       malloc_gzip
arch/powerpc/xmon/ansidecl.h:#define    const
drivers/gpu/drm/nouveau/nvkm/subdev/bios/init.c:#define error(fmt,
args...) bioslog(ERROR, fmt, ##args)
include/linux/compiler_attributes.h:#define   noinline
__attribute__((noinline))
include/linux/decompress/mm.h:#define malloc(a) kmalloc(a, GFP_KERNEL)
include/linux/raid/pq.h:#define noinline __attribute__((noinline))
lib/inflate.c:#define malloc(a) kmalloc(a, GFP_KERNEL)
tools/include/linux/compiler-gcc.h:#define  noinline
__attribute__((noinline))
tools/include/linux/compiler.h:#define noinline
tools/testing/selftests/futex/include/logging.h:#define error(message,
err, args...) \

None of these should make a problem. And it would may avoid people
using such common-name-macros in the future ;-)

Cheers,
Miguel
