    Merge branch 'parisc-4.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
    
    Pull parisc fixes from Helge Deller:
    
     - a patch to change the ordering of cache and TLB flushes to hopefully
       fix the random segfaults we very rarely face (by Dave Anglin).
    
     - a patch to hide the virtual kernel memory layout due to security
       reasons.
    
     - two small patches to make the kernel run more smoothly under qemu.
