ia64: Don't use create_proc_read_entry()
Don't use create_proc_read_entry() as that is deprecated, but rather use proc_create_data() and seq_file instead. Signed-off-by: David Howells <dhowells@redhat.com> cc: Tony Luck <tony.luck@intel.com> cc: Fenghua Yu <fenghua.yu@intel.com> cc: linux-ia64@vger.kernel.org Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
