43 | * These macros are copied from sys/cpu/x86_64/include/types.h. | |
44 | * It's okay to copy from arch dependent header because x86_64 is the only | |
45 | * supported arch, and no other arch is going to be supported any time soon. | |
46 | * | |
47 | * These are supposed to be able to be included from userspace by defining | |
48 | * _KERNEL_STRUCTURES, however this scheme is badly broken that enabling it | |
49 | * causes compile-time conflicts with other headers. Although the current | |
50 | * upstream code no longer requires _KERNEL_STRUCTURES, they should be kept | |
51 | * here for compatibility with older versions. | |
