Merge tag 'xtensa-for-next-20140221-1' into for_next

Xtensa fixes for 3.14:
- allow booting xtfpga on boards with new uBoot and >128MBytes memory;
- drop nonexistent GPIO32 support from fsf variant;
- don't select USE_GENERIC_SMP_HELPERS;
- enable common clock framework support, set up ethoc clock on xtfpga;
- wire up sched_setattr and sched_getattr syscalls.

+
+                The timeout depends on the max number of available cards
+                in the system and the maximum allowed queue size.
+
+                The driver ensures that the settings are done just before
+                the VFs get enabled. Changing the timeouts in flight is not
+                possible.
