 "Nothing exiting in this patchset, just

   - small cleanups of header files

   - default to 4 CPUs when building a SMP kernel

   - mark 16kB and 64kB page sizes broken

   - addition of the new io_pgetevents syscall"

  parisc: Build kernel without -ffunction-sections
  parisc: Reduce debug output in unwind code
  parisc: Wire up io_pgetevents syscall
  parisc: Default to 4 SMP CPUs
