Pull parisc fixes and cleanups from Helge Deller:
 "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-4.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
  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
  parisc: Convert printk(KERN_LEVEL) to pr_lvl()
  parisc: Mark 16kB and 64kB page sizes BROKEN
  parisc: Drop struct sigaction from not exported header file
