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. Signed-off-by: Chris Zankel <chris@zankel.net>
