Merge branch 'parisc-4.3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

Browse Source 
Pull parisc updates from Helge Deller:
 "The most important change is that we reduce L1_CACHE_BYTES to 16
  bytes, for which a trivial patch for XPS in the network layer was
  needed.  Then we wire up the sys_membarrier and userfaultfd syscalls
  and added two other small cleanups"

* 'parisc-4.3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
  parisc: Change L1_CACHE_BYTES to 16
  net/xps: Fix calculation of initial number of xps queues
  parisc: reduce syslog debug output
  parisc: serial/mux: Convert to uart_console_device instead of open-coded
  parisc: Wire up userfaultfd syscall
  parisc: allocate sys_membarrier system call number
