[GIT PULL] parisc architecture updates for kernel v4.20

[Helge Deller <deller@gmx.de>]

Hi Linus,

please pull the parisc architecture patches and fixes for 4.20-rc1 from:

  git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-4.20-1

Lots of small fixes and enhancements, most noteably:

- Many TLB and cache flush optimizations (Dave)
- Fixed HPMC/crash handler on 64-bit kernel (Dave and myself)
- Added alternative infrastructre. The kernel now live-patches itself
  for various situations, e.g. replace SMP code when running on one CPU
  only or drop cache flushes when system has no cache installed.
- vmlinuz now contains a full copy of the compressed vmlinux file. This
  simplifies debugging the currently booted kernel.
- Unused driver removal (Christoph)
- Reduced warnings of Dino PCI bridge when running in qemu
- Removed gcc version check (Masahiro)

Thanks,
Helge
