Pull tensa fixes from Chris Zankel:
 "This series includes fixes for potentially serious bugs in the
  routines spilling processor registers to stack, as well as other
  issues and compiler errors and warnings.

   - 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.
   - fix system call to spill the processor registers to stack.
   - improve kernel macro to spill the processor registers
   - export ccount_freq symbol
   - fix undefined symbol warning"
