> 1) does sparc64 access_ok() need to differ for 32bit and 64bit tasks? sparc64 will just fault no matter what kind of task it is. It is impossible for a user task to generate a reference to a kernel virtual address, as kernel and user accesses each go via a separate address space identifier. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
