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

51 | * | |
52 | * These are supposed to be able to be included from userspace by defining | |
53 | * _KERNEL_STRUCTURES, however this scheme is badly broken that enabling it | |
54 | * causes compile-time conflicts with other headers. Although the current | |
55 | * upstream code no longer requires _KERNEL_STRUCTURES, they should be kept | |
