- * kern_addr_valid(ADDR) tests if ADDR is pointing to valid kernel
- * memory.  For the return value to be meaningful, ADDR must be >=
- * PAGE_OFFSET.  This operation can be relatively expensive (e.g.,
- * require a hash-, or multi-level tree-lookup or something of that
- * sort) but it guarantees to return TRUE only if accessing the page
- * at that address does not cause an error.  Note that there may be
- * addresses for which kern_addr_valid() returns FALSE even though an
- * access would not cause an error (e.g., this is typically true for
- * memory mapped I/O regions.
- *
- * XXX Need to implement this for parisc.
