workqueue: skip the node_nr_active update for non-unbound workqueuesgrafted
apply_wqattrs_commit() updates node_nr_active->max unconditionally. wq->node_nr_active[] is only allocated for unbound workqueues, so guard the call before per-cpu workqueues start using this path. No functional change: only unbound workqueues reach apply_wqattrs_*() today. Signed-off-by: Breno Leitao <leitao@debian.org> Signed-off-by: Tejun Heo <tj@kernel.org>

+=================================
+Linux on the Nios II architecture
+=================================
+
+This is a port of Linux to Nios II (nios2) processor.
+
+In order to compile for Nios II, you need a version of GCC with support for the generic
+system call ABI. Please see this link for more information on how compiling and booting
+software for the Nios II platform:
+http://www.rocketboards.org/foswiki/Documentation/NiosIILinuxUserManual
+
+For reference, please see the following link:

+
+What is Nios II?
+================
+Nios II is a 32-bit embedded-processor architecture designed specifically for the
+Altera family of FPGAs. In order to support Linux, Nios II needs to be configured
+with MMU and hardware multiplier enabled.
+
+Nios II ABI
+===========
+Please refer to chapter "Application Binary Interface" in Nios II Processor Reference
+Handbook.
