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