Subject: [GIT PULL] parisc architecture fixes for 4.16-rc4

Hi Linus,

please pull a few small updates and fixes for the parisc architecture from:

  git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-4.16-1

Changes:
- 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.

Thanks,
Helge
