I am not sure if the macro exists, but, since the Kernel occupies the first half of the virtual address space, the following macro would work for a Kernel meant for a 32-bit architecture. #define KERNEL_VOK(addr) ((addr) < (0x80000000U)) Assuming that the addr passed is an unsigned quantity. This should be easily extensible for other architectures. -- Vimal -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [email protected] Please read the FAQ at http://kernelnewbies.org/FAQ
