47 | * These macros are copied from sys/cpu/x86_64/include/types.h. | |
48 | * It's okay to copy from arch dependent header because x86_64 is the only | |

50 | * | |
51 | * These are supposed to be able to be included from userspace by defining | |

53 | * causes compile-time conflicts with other headers. Although the current | |
54 | * upstream code no longer requires _KERNEL_STRUCTURES, they should be kept | |
